Disable button after submit in Asp.net

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;
}

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

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.

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

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">

Download Ajax Loading Image

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:

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

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

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" />

Call a C# Method from aspx Page

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

Here is a simple example:

In your aspx page

2. protected void Page_Load(object sender, EventArgs e)


3. {


4. lbllable.DataBind();


5. }


6. public string GetCustomerID


7. {


8. get { return this._CustomerID; }


9. }

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;

Validating Checkboxlist using CustomValidator

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 %>');

{
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)

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

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

Integrating FCKeditor in Asp.net Websites

FCK Editor With Custom Validation in Asp.net

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
