Detecting RadioButton being checked

[RebLazer]

When I try this:

Sub Page_Load(Sender As Object, E As EventArgs)

If (Object.ReferenceEquals(Sender, geog_all)) Then
trace.warn("USER CLICKED geog_all BUTTON - don't hide DataGrid1&quot
end if

...


The compiler complains:
Compiler Error Message: BC32022: 'Public Event CheckedChanged(sender As Object, e As System.EventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.


What I am trying to do is execute that IF block whenever radiobutton "geog_all" is checked and, thereby, does an autopostback which fires page_load.

What's the right way to do this, please?

Please help!
Thanks,
RebLazer

OOPS - that code was supposed to read:

Sub Page_Load(Sender As Object, E As EventArgs)

If (Object.ReferenceEquals(Sender, geog_all.checkedChanged)) Then
trace.warn("USER CLICKED geog_all BUTTON - don't hide DataGrid1&quot
end if

...

Thanks!

I'm not doing very well here... That code in the previous post is what is not correct. It (i.e. with the red text) is what is causing that compiler error (in the first post of this thread).

Sorry for the confusion - PLEASE HELP!!!

Thanks!

I may be missing your point here, but a radio button has a .checked property, which is what it sounds like you are after:

if geog_all.checked then
'the radio button was checked
else
'it wasn't checked
end if

Link9,

Thanks for your reply.

Let me clarify.

My page looks like this: I've got three radiobuttons (all in the same group) that are autopostback=true. I have other things on the page that *also* cause a postback. I am trying to distinguish which one caused the postback. It is possible to have "geog_all" checked, without it being the cause of the post back - something else on the page may be the cause. So ".checked=true/false" won't do it. I need to be able to tell what triggered page_load to be called.

Thanks again!
