Steve,
I saw your sample and also I created my control based on your combobox
sample.
But my page is not even showing up the control.
Can you please let me know what I am missing?
Thanks

news:ux**************@TK2MSFTNGP09.phx.gbl... Hello All,
I am trying to write Web Controls and in most of the samples I came
across, I am seeing the following function where a HTML string is written
to create HTML Controls.
/// <summary>
/// Render this control to the output parameter specified.
/// </summary>
/// <param name="output"> The HTML writer to write out to </param>
protected override void Render(HtmlTextWriter output)
{
string TheHTMLString = FrameHTMLString() ;
output.Write(TheHTMLString) ;
}
Is it possible for me to use the asp:button or asp:panel in this
webcontrol. Also how will I setup events for such button click or panel
mouse down event?
Any suggestions please?
Thanks
Aand Ganesh
