I have a GridView(GV) and inside the GV I have a databound column. The column has a Checkbox in it and I have tried to wire up the OnCheckedChanged event to a code block in the code behind file. The event signature is correct I just can't get it to fire. The GV is inside of a Update panel. Any ideas?

Class _Default : Inherits Page

  Protected Sub cb_cc(sender As Object, e As EventArgs)
   'do stuff
  End sub
... 

<asp:CheckBox ID="cb" runat="server" Checked="false" OnCheckedChanged="cb_cc" />

I don't use ASP so I'm just guessing that your sub should be Public(?).

I have tried that. Most events are done with Protected Sub, so I was following a pattern. Thanks for the thought.

I believe you need AutoPostBack=true but it is a little more involved when the checkbox is in a GridView, as the GV handles the assignment of IDs. SO discussion.

I have tried the AutoPostback as well. I have done some serious searching and did not find that post - thanks for that. It will lead me into some more research.

Let me now add more complexity - I am using the footer template of a column. All columns are in templates.

I think I will redesign what I am doing and remove that from the GV. It just looked very nice there in the footer.

Turns out I was wrong about the event signature (e As EventArgs) is correct and it works now!

He,he, I did spot that at one point! I don't know why I didn't mention it. Andy.

Well not all event signatures are the same - the DropDownList onselectedIndexChanged is as above on my first post - inconsistant as best!

That's interesting (I've never used VB with ASP.NET). I'm surprised that the event handlers' signatures would take a different number of arguments.
