function OpenWindow(url)

{
   newwindow = window.open(url, 'mywindow', 'width=500,height=400'); 

}

Now In .aspx.cs page or server side to use the javascript window open you have to use the following code

StringBuilder popupScript = new StringBuilder();
popupScript.Append("");
// if you are using script manager - update panel then this

Using String.Format("{0}", "formatting string"}; in Asp.net

2009-09-09T23:21:00.000+05:30

Many times we want to define formats for date, currency, number etc

For example if we want date in

" 09 September 2009" - String.Format{0:D}

" 09 September 2009 12:30" - String.Format{0:f}

Like this various formats for date, month, year, time, currency number etc can be seen at :

Inserting Data Into Table Using Select Query

2009-09-01T18:03:00.001+05:30

In SQL, sometimes we need to select some data from one table and insert data into another table, this can be done as follows with a simple sql query:

Insert into Table1 (c1, c2, c3, c4, c5)
(Select c1, c2, c3, c4, c5 from Table2)
But make sure that both the tables have same fields, data type..

Textbox Watermark using Ajaxtoolkit or By Javascript

2009-08-31T16:24:00.001+05:30

Adding Watermark to textbox can be done in two ways:

1) Using Ajax Toolkit:

<asp:TextBox runat="server" id="txtname"/>

<ajaxToolkit:TextBoxWatermarkExtender ID="TBWE2" runat="server"
   TargetControlID="TextBox1"
   WatermarkText="Type First Name Here"
   WatermarkCssClass="watermarked" />

For more information on Ajax Toolkit please visit:
http://www.asp.net/ajax/

2) Using Javascript:

<asp:TextBox ID=”txtname” runat=”server” Text = “Please Enter your Name here”
onblur = “TextboxWaterMark(this, event);”
onfocus = “TextboxWaterMark(this, event);”>
</asp:TextBox>

<script type = “text/javascript”>
var Text = “Please Enter your text here”;//black

function TextboxWaterMark(txtid, evnt)
{
if(txtid.value.length == 0 && evnt.type == “blur”)
{
txtid.style.color = “set the color you want”;//red
txtid.value = Text;
}
if(txtid.value == Text && evnt.type == “focus”)
{
txtid.style.color = “set the color you want”;
txtid.value=”";
}
}
</script>

To use in code behind :

txtname.Attributes.Add(”onblur”, “TextboxWaterMark(this, event);”);

txtname.Attributes.Add(”onfocus”, “TextboxWaterMark(this, event);”);

Disable button after submit in Asp.net

2009-08-28T19:54:00.001+05:30

Once the user has filled the form details, or did any kind of changes and clicked on submit button, if we want to prevent the duplicate data entry and show other message like "please wait.."'then we can do this as below:

<asp:Button  runat="server" ID="btnsubmit" Text="Submit"
OnClick="btnsubmit_Click" UseSubmitBehavior="false"
OnClientClick="this.disabled=true;this.value='Please wait..';"   />

For <asp:imagebutton> usesubmitbehavior will not work hence for this:

<asp:ImageButton runat=”server” ID=”btImageButton”
ImageUrl=”/images/submit.jpeg” OnClick=”btImageButton_Click”
OnClientClick=”javascript: Submit(this);” />

<script type=”text/javascript” language=”javascript”>

function Submit(c){
Page_ClientValidate();
if (Page_IsValid){
c.disabled = true
__doPostBack(c.name, ”);
}
return Page_IsValid;
}

</script>

Preview/Show Uploaded Image in Asp.net

2009-08-26T18:14:00.000+05:30

Sometimes, we want to give the preview of the image uploaded through file upload control in asp.net, at the same time.

There is a very nice article on this.. using server side.

http://dotnetspider.com/resources/31341-Show-Uploaded-Image-Image-Control-Asp-net.aspx

In this article, we have one image control, one file upload control and one button control

We upload image using file upload control, and then click on upload button, at the same time the image uploaded will be shown in the image control..

Getting Last Modified/Created Table, Stored Procedure, Function.. in Sql Server

2009-08-25T16:39:00.001+05:30

Sometimes, we want to know how many tables, stored procedures or functions we have created on a particular day, or on which tables, sps or functions, modifications have occured. All this can be known through a very simple sql query, which is as below:

select name,type,type_desc, create_date, modify_date from sys.objects

where convert(varchar,modify_date,101) = convert(varchar,getdate(),101)

order by modify_date desc

Here

name : - "Its the table or sp or function name"

type: - "To identify a table or sp or function etc.. P, S, U"

type_desc: -"Description whether it is table, sp etc.."

- S = System Table, PK = Primary Key,U = User Table,

- P= Stored Procedure, TF = Table Value Function,

- FN = Scalar Function, D= Default Constraint

create_date: - "Date when it is created"

modify_date: - "Last modified datetime of table, sp,.. etc"

In above query, in place of getdate(), you can pass the date you want, also you can get complete list after removing where condition, just giving order by modified date from sys objects..

Very important when we want to generate scripts for particular tables, sps or function for a particular date.

Changing Css Class or Style At Run time dynamically in Asp

2009-08-22T10:37:00.000+05:30

You can add/change css style or add new attributes to current style at runtime, in asp.net code behind.

Lets say you have:

Download

Now if we want to change its class dynamically then in code behind we have to do:

linktemp.Attributes.Add(”class”, “verdana13greynormalitalic”);

if we want to change its text-decoration under style then,

linktemp.Style.Add(”text-decoration”, “none”);

in the similar you can add new styles, change visible option to true/false,

linktemp.Style.Add(”display”, “block”);

Limiting the number of records to be displayed in Crystal Report

2009-08-20T19:09:00.000+05:30

You might be working with crystal reports, and so must have a noticed that number of records displayed in crystal report are variable, sometimes, it displays 8, sometimes 10.. and so on according to the data, it sets it accordingly.

But we can handle this scenario i.e we can specify how many records we want the crystal report to display. For this you need to follow the below instructions:

To make it show 10 records per page do the following

1. Open the report in Design View

2. Right click on the Details section and select Section Expert

3. Make sure the Details section is selected in the Section Expert dialog box. Check the box that says “New Page After”

4. Click the formula editor button to the right of the checkbox.

5. Enter the following formula

if Remainder (RecordNumber, 10) = 0 then true else false

6. Click Save and Close and then click OK.

If you run the report it should break after each 10 rows.

Get Only Date from Datetime in Sql

2009-06-02T23:34:00.000+05:30

Sometimes we need to have only date from datetime field in sql.

There are number of ways to accomplish that:

Suppose we take current date

select getdate()

now to take only date from current date excluding time, we do as follows in various ways:

select DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))
select convert(varchar,getdate(),101)
select convert(char(8),getdate(),1)
select cast(cast(getdate() as int) as datetime)
select cast(convert(varchar,getdate(),110) as datetime)

Adding eWorld.UI (Excentrics World) Calendar Popup, TimePicker.. etc in Asp.net

2009-06-01T23:24:00.000+05:30

You might be in need of Calendar popup or Time Picker in asp.net. I have being using eworld's calendar popup and time picker control since many years.. and all i can say that they are fantastic fully loaded with various features... No Need of taking a textbox and a calendar control for binding date.. and adding different validations for valid date, past and future date validation... now all that comes in one place just drag and drop one calendar popup control and it will give you access to multiple features..

Also there is no time picker control available in our asp.net toolbox.. i searched a lot over the internet and i found this one..

You can download the eworld ui toolkit from :

http://www.eworldui.net/Download.aspx

Toolkit is available for various .net versions whether it is 1.0, 2.0 or 3.5

Once Downloaded, unzip the rar file and install the given exe..

Also, Once done copy the eWorld.UI.dll and paste it in the bin folder of your web application and then right click the web site and add reference of that dll.

Then In the Visual Studio ->View ->Tool box -> Right Click ->Add Tab -> give Eworld Toolkit (as name) - > Right click ->choose items and browse to the eworld ui dll and once done you will see many contorls under that tab in the tool box..

I have been using

CalendarPopup

Time Picker

RangeValidator

CustomValidator

MaskedTextbox...

there are lots of other controls too which you can try at your lease..

Once done.. you can drag and drop the calendar popup on to the aspx page and you will see:

<ew:CalendarPopup ID="tb_startupdate"
runat="server" ControlDisplay="TextBoxImage" ImageUrl="~/Images/dtpicker.jpeg">
</ew:CalendarPopup>

SQL SERVER – Fix : Management Studio Error : Saving Changes in not permitted. The changes you have made require the following tables to be dropped and

2009-05-31T00:35:00.000+05:30

I encountered problem when modifying table in SQL Server 2008, Once the table is created open the table in SSMS by clicking on the table name and selecting “Design.” Try to include another column to the existing table and click on save (CTRL+S). It will prevent it from saving and will emit the following error in popup.
Saving Changes in not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that can’t be re-created or enabled the option Prevent saving changes that require the table to be re-created

Download Ajax Loading Image

2009-05-31T00:34:00.001+05:30

Since all the Ajax interactions happen behind the scenes asynchronously, the user doesn't understand what's going on: sometimes the user doesn't need to know what's going on (like when you are just reloading some data), but when he presses a button he needs to know that he did the right thing and that something is happening.

So we can show an "ajax loading image" when ajax process is going on..

You can generate these images from:

http://www.ajaxload.info/

You can also download from:

http://mentalized.net/activity-indicators/

Also you can search the google for ajax loading image and you will be able to see lots of images..

Validating Extension(eg. (.aspx/.html/.jpeg....) in asp.net using Regular Expression

2009-05-31T00:33:00.001+05:30

When you want to validate that the text entered must have particular extension that you have decided.

for example if you have a textbox to enter page name. You want the user to enter page name with ".aspx" extension. Then you have to use the following regular expression validator.
<asp:RegularExpressionValidator ErrorMessage=" Please Enter page name with .aspx extension"
ID="RegularExpressionValidator1" runat="server"
ValidationExpression="^.*\.(aspx)$" ControlToValidate="txturl" Display="Dynamic" ></asp:RegularExpressionValidator >

so now if the user enters "hello.abc" then validation will fire with message "Please enter page name with .aspx extension"

Thus with this ValidationExpression="^.*\.(aspx)$"

you can specify any extension like gif, jpeg or whatever you want..

^.*\.(exe|bat|etc)$

Set meta tag in asp.net programmaticaly for seo friendly websites

2009-05-31T00:32:00.001+05:30

When you are developing SEO friendly websites, the first basic thing for seo is meta tags, as all search engines are looking for these meta tags while querying the database. Here we will allow the user to set the "keywords" and "description" (the two parts of meta tag)and then set the meta tag programmatically.

This is how meta tags are set dynamically:

HtmlMeta mKey = new HtmlMeta();
mKey.Name = "keywords";
mKey.Content = "home, blog";
this.Page.Header.Controls.Add(mKey);

HtmlMeta mdesc = new HtmlMeta();
mdesc.Name = "description";
mdesc.Content ="home page";
this.Page.Header.Controls.Add(mdesc);

after doing that you can view in the "View Source" of the page you have set meta tags under the head section.
<meta name="keywords" content="home,blog" />
<meta name="description" content="home page" />

Read/Acess globalization section of system.web from web.config

2009-05-31T00:31:00.001+05:30

To read web.config, and find any section there are number of solutions available, one such method to access globalization section which is under system.web of web.config is as follows:

In web.config i have

<globalization uiCulture="nl-NL" />

Now to read the uiculture in codebehind file in asp.net

string uicul = ((System.Web.Configuration.GlobalizationSection)(System.Configuration.ConfigurationSettings.GetConfig("system.web/globalization"))).UICulture;

Lets say for example i have to display date according to culture set in web.confg so:

public object GetDateCulture(object date)
{
string uicul = ((System.Web.Configuration.GlobalizationSection)(System.Configuration.ConfigurationSettings.GetConfig("system.web/globalization"))).UICulture;
System.IFormatProvider format = new System.Globalization.CultureInfo(uicul, true);
date = Convert.ToDateTime(date).ToString("dd MMM yyyy", format);
return date;
}

Ouput will be:

if culture is english : 22 May 2009

if culture is dutch : 22 Mai 2009

Call a C# Method from aspx Page

2009-05-31T00:30:00.000+05:30

Sometimes you need to call a method written in codebehind(.aspx.cs) from .aspx page.

Here is a simple example:

In your aspx page

<asp:Label ID="lbllable" runat="server" text='<%# GetCustomerID() %>' />

In your codebehind(.aspx.cs) page

private string _CustomerID = "8888";

protected void Page_Load(object sender, EventArgs e)

{

lbllable.DataBind();

}

public string GetCustomerID

{

get { return this._CustomerID; }

}

When you are using in gridview or any other data bound control then

in your aspx page

<%# GetEmployee(Eval("EmpId"))%>

in your codebehind

public object GetEmployee(object EmpId)

{

EmpId = 1234;

return EmpId;

}

Validating Checkboxlist using CustomValidator

2009-05-29T23:09:00.000+05:30

You might be knowing that required field validator doesn't works with required field validator... so to accomplish that purpose we can use custom validator to validate checkbox list.

<asp:CheckBoxList ID="chkModuleList"runat="server" >
</asp:CheckBoxList>

1) Using ClientValidationFunction

<asp:CustomValidator runat="server" ID="cvmodulelist" ClientValidationFunction="ValidateModuleList" ErrorMessage="Please Select Atleast one Module" ></asp:CustomValidator>

function ValidateModuleList(source, args)
{
var chkListModules= document.getElementById ('<%= chkModuleList.ClientID %>');
var chkListinputs = chkListModules.getElementsByTagName("input");
for(var i=0;i<chkListinputs .length;i++)
{
if(chkListinputs [i].checked)
{
args.IsValid = true;
return;
}
}
args.IsValid = false;
}

2) Using OnServerValidate

<asp:CustomValidator runat="server" ID="cvmodulelist" OnServerValidate="ValidateModuleList" ErrorMessage="Please Select Atleast one Module" ></asp:CustomValidator>

private void ValidateModuleList(object sender, ServerValidateEventArgs e)
{
int cnt= 0;

for(int i=0;i<chkModuleList.Items.Count;i++)
{
if(chkModuleList.Items[i].Selected)
{
cnt++;
}

e.IsValid = (cnt== 0) ? false : true;
}
}

Reset/Clear all fields - Textbox/Dropdown/Radionbuttonlist/Listbox etc of a web form in Asp.net

2009-05-27T23:52:00.001+05:30

In most of the case after inserting data into database or carrying out any other transactions. in which we have one form that contains bunch of textbox's, radiobuttonlist, checkboxlist, dropdownlist, checkbox, listbox etc or any other controls in asp.net .now after inserting data, on submit/save click we want to empty/reset/clear all controls in the web form, we actually do like this:

txtid.text ="";
ddid.SelectedIndex = -1;

and so on... and that for each textbox, dropdowns... etc it becomes very tedious and long.. so to make it short we should create a common function to reset all controls in web form...

Here is the ready made function :

Step 1:

///
/// Pankaj lalwani
/// Reset all textbox/radiobutton/dropdowns/listbox
///
///
public static void ClearFields(ControlCollection pageControls)
{
foreach (Control contl in pageControls)
{
string strCntName = (contl.GetType()).Name;
switch (strCntName)
{
case "TextBox":
TextBox tbSource = (TextBox)contl;
tbSource.Text = "";
break;
case "RadioButtonList":
RadioButtonList rblSource = (RadioButtonList)contl;
rblSource.SelectedIndex = -1;
break;
case "DropDownList":
DropDownList ddlSource = (DropDownList)contl;
ddlSource.SelectedIndex = -1;
break;
case "ListBox":
ListBox lbsource = (ListBox)contl;
lbsource.SelectedIndex = -1;
break;
}
ClearFields(contl.Controls);
}
}

Step 2:
Call this method on submit/save click after your code ends or sometimes when you provide clear/reset button to empty all fields

ClearFields(Form.Controls);

Data Navigation with the ListView & GridView, DataPager and SliderExtender Controls

2009-05-27T00:01:00.001+05:30

Listview - Its a new control in asp.net 3.5, similar to gridview but much more capabilities than gridview..
Also Datapager - a new control in asp.net 3.5 used for data paging.
SliderExtender - a control of ajax toolkit

Combining all these three you can do wonders...

Below is an example of listview with datapager and slider extender

http://mattberseth.com/blog/2007/12/data_navigation_with_the_listv.html

Another example is of gridview with dataper and slider extender

Disable Copy/Paste in asp.net textbox

2009-05-23T23:48:00.000+05:30

Sometimes you don't want to allow user to copy/paste or (Ctrl + C)/(Ctrl + V) in asp.net textbox.

You have to use onCopy="return false" onPaste="return false"

Here is an example of that:

<asp:TextBox ID="tb_Email" runat="server"
onCopy="return false" onPaste="return false" ></asp:TextBox>

This will restrict user from directly copy/paste into textbox, they have to type manually.

Set Language in Sql Server

2009-05-23T00:46:00.000+05:30

When you are working with multi lingual web applications, you may need to retrieve data like month name, day name etc to be displayed in different languages. For example month "June" is in English, its dutch translation would be "Juni" .This is possible with "Set Language languagname" feature of sql server. where language name is the name of language you want to set.. you can complete list of languages that sql support using

"select * from sys.syslanguages"

Below is one example using set language, retrieving day and month name in different languages:
DECLARE @Today DATETIME

Integrating FCKeditor in Asp.net Websites

2009-05-21T23:30:00.000+05:30

You might be using textarea, to input large text, but formatting is not possible with that, for that you needed WYSIWYG editor. There are plenty of rich text editors available in the market, but i would recommend you to use FCK Editor which is opensource freely available. I have to implement FCKEditor with my Asp.net Website, the following link explains in detail how to integrate with your asp.net websites.

Part I:

FCK Editor With Custom Validation in Asp.net

2009-05-15T00:22:00.001+05:30

I have to keep validation for fckeditor in my application, but then i came to know that Requiredfield Validator control of asp.net does not work with fckeditor. So I used CustomValidator control of asp.net and it worked perfectly.

You might be aware that customvalidator works in both ways. either clientsidevalidation function using javascript and servervalidate. Difference between them is servervalidate method takes server trip while in clientsidevalidation all validations fire at once without server trip.

I will be showing you both ways:

1) Using ClientValidationFunction

<script language="javascript" type="text/javascript">
function ValidateFCK(source, args) {

var fckBody = FCKeditorAPI.GetInstance('<%=FCKeditor1.ClientID %>');
args.IsValid = fckBody.GetXHTML(true) != "";
}
</script>

<FCKeditorV2:FCKeditor ID="FCKeditor1" BasePath="../fckeditor/" runat="server">
</FCKeditorV2:FCKeditor>

<asp:CustomValidator runat="server" ErrorMessage="Please Enter Description" ID="CustValDesc" ControlToValidate="FCKeditor1"
ClientValidationFunction="ValidateFCK" ValidateEmptyText="True"></asp:CustomValidator>

Note: Sometimes this method does not works with multiple browsers.

2) Using OnServerValidate

<FCKeditorV2:FCKeditor ID="FCKeditor1" BasePath="../fckeditor/" runat="server">
</FCKeditorV2:FCKeditor>

<asp:CustomValidator runat="server" ErrorMessage="Please Enter Description" ID="CustValDesc" ControlToValidate="FCKeditor1"
ValidateEmptyText="True" onservervalidate="CustValDesc_ServerValidate"></asp:CustomValidator>

protected void CustValDesc_ServerValidate(object source, ServerValidateEventArgs args)
{
if (FCKeditor1.Value == string.Empty )
{
args.IsValid = false;
}
else
{
args.IsValid = true;
}
}

Note:

Whenever you are submitting form and you have kept validations, always check whether the page is valid or not by:

if (Page.IsValid)
{

//your code

}

I also found some other method which works for Requiredfield validator with fckeditor is
EnableClientScript="false" and

InitialValue="<br/>"

<asp:RequiredFieldValidator ID="req_Description" runat="server" ControlToValidate="FCKeditor1"
Display="Dynamic" InitialValue="<br/>" Text="Please Enter Description"
EnableClientScript="false"></asp:RequiredFieldValidator>

Working with view states in flex

2009-05-06T00:00:00.000+05:30

View state as name suggests while working in flex when you want to switch from one state to another state <mx:state> are used.

For example if you want to create login and register modules. so your first state is register and second state is login. so you can keep the register code in one state and set it as start state and keep the login code in another state. and after sucessful registration you want the login state to be enabled.. so you can achieve that using actionscript.. for all above you need to make use of <mx:state> below is the example i referred while accomplishing that...
