Hi,
I am trying to get the HTML of a button and display it in the textbox
in this case. But I always get this error at runtime :
"Control 'Button1' of type 'Button' must be placed inside a form tag
with runat=server."
As you see, the controls HAVE been placed inside the <form
runat="server"> tags. Please help me with this.
Pls give some code snippets if there some other way of getting HTML of
a control.
Thanks !!
