Hi

I am adding LinkButton to my panel in the same way as you suggested. But I 
am adding this Link button in one of my Sub ROUTINEs instead of SUB 
Page_Load()

I am not able to set AddHandler for this Link Button.

Also If i create LinkButton in the form iteself ratehr than 
programatically, it does access the btnLink_Click SUB.

The code looks as follows

Function AddLinkButton()

 Dim lnkButton as New LinkButton()
 lnkButton.Text= "Click Here"
 AddHandler lnkButton.Click, AddressOf btnLink_Click
 panel1.Controls.Add(lnkButton)

end function

Sub btnLink_Click(obj as object, e as EventArgs)
 Response.Write("Clicked Link Button")
End Sub


Any Suggestion are greatly appreciated. 

Thanks In Advance

I ran into this same issue a while back when I was trying to dynamically
generate a whole form based on the database layout from a tabstrip control.
The answer given to me was you were unable to add event handlers after the
page_load due to the page execution model.  It was described as a
bug/limitation of the framework.  If anyone has a better explanation I'd
love to hear it because I refuse to believe .net can't do this (or anything
for that matter).
