Datagrid SelectedIndexChanged

[BasicBoy]

I have a datagrid bound to data - but when I click on it, it does not fire the datagrid.selectedindexchanged event.
What can the problem be ?

Thanks

have you wired the handler to the event? this can be done in markup, or code behind.

No I have not specifically - I thought it is automatically wired up if you double click the control and write the event code.
Can you tell me how to wire up

Thanks

either

<asp:gridview onselectedindexchanged="do_something" >

or

protected override OnInit(EventArgs e)
{
   base.OnInit(e);
   my_grid_view.SelectedIndexChanged += do_something; 
}

then you will have the handler

protected void do_something(object sender, GridViewSelectedIndexChangedEventArgs e)
{
   // your code here.
}

Thanks jmeckley
1. Slower please - I have not done this before. I am working in vb.net and not C# - your code looks like C#.
2. Where do I put protected override - is it in the #Region
3. Where will I see the protected void - do something.
4. Is do something a routine in code behind ?

Here is a routine in another web program which works and it triggers the event but I do not know why here and why not in my new program

Public Sub dgCats_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dgCats.SelectedIndexChanged

Dim IDNo As Integer, ThisCatname As String
IDNo = dgCats.SelectedItem.Cells(0).Text
ThisCatname = dgCats.SelectedItem.Cells(1).Text
Response.Redirect("listings.aspx?Type=Cat&ID=" & IDNo)
End Sub

Post your HTML source code and any code-behind code that you have.

1. C#, there are translators on the web.
2. in the code behind. #regions are for people, not the compiler. I don't use them as it makes it easy to have member explosion within a class.
3. in code behind
4. yes
