Dynamic ImageButton EventHandler in ASP.Net

   End Sub

 

Doesn't work

 

It creates the table, the row, the cell and the button, but clicking on the button does nothing.

 

I am about to use an image instead and wrap it with <a href=></a>, but wanted to see if I left something out first

[PlausiblyDamp]

Not sure what is happening with

but = New System.Web.UI.WebControls.ImageButton
but = BuildButton(sImageUrl & "N-Home.gif", "btnHome", glob.butHome.sReDirect)

but the first of those two lines is redundant as you never use the instance of ImageButton that it creates.

 

If you put a breakpoint on the event handler is it ever reached?

Yes, I have been messing around with it and just copied it

 

When it invokes the handler, it creates a button that does nothing when you click on it
