I have an ASP.NET custom control, which contains a DataGrid with
checkboxes. I am trying to figure out how to retrieve the selected
records, based on the checkbox's checked state. I want to send the
results to a list control on the containing .ASPX page.

Here is what I have in my code behind (C#):

<%@ Page language="c#" Codebehind="WebForm1.aspx.cs"
AutoEventWireup="false" Inherits="WebApplication5.WebForm1" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<title>WebForm1</title>
<meta content="Microsoft Visual Studio .NET 7.1"
name="GENERATOR">
<meta content="C#" name="CODE_LANGUAGE">
<meta content="JavaScript" name="vs_defaultClientScript">
<meta content="http://schemas.microsoft.com/intellisense/ie5"
name="vs_targetSchema">
</HEAD>
<body MS_POSITIONING="GridLayout">
    <form id="Form1" method="post" runat="server">
    <div style="OVERFLOW: auto; WIDTH: 100%; HEIGHT: 200px">
    <asp:DataGrid id="DataGrid1" runat="server" style="Z-INDEX: 102;
LEFT: 24px; POSITION: absolute; TOP: 32px" Height="120px">
<Columns>
<asp:TemplateColumn>
    <ItemTemplate>
    <INPUT type="checkbox">
    </ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:DataGrid></div>
</form>
</body>
</HTML>

I looked for examples via Google, Yahoo, etc. but couldn't find much in
the way of C#. Any help would be appreciated.

sianan,

I have example code for doing exactly this on my website.
http://www.aboutfortunate.com?page=codelibrary

Use the textbox there to search for "checkbox in datagrid" and you'll have
the example code.

Thank you for the response!

I did indeed find the code, the problem is that it is in VB.NET. For
some reason, I wasn't able to convert it into C#. Still trying.....

Sianan,

I'd be happy to help you convert it. Send me what you have so far if you'd
like (less typing for me that way) or tell me where you're hung up.

You'll have to loop through the grid rows, using a FindControl() to grab the
checkbox, (you'll have to give the checkbox and id). At that point you can
check the true/false of the checked property.
