I am hoping somebody from this group can help me out here...
I have been trying to add an array of ImageButtons to my WebForm however I
keep getting an exception that I can't seem to find an answer for any where
on the net.
Any help in the right direction would be greatly appreciated. If more
code/source is need please let me know and I will post more.

CJ

<end code --Hi CJ,
If you add ImageButton to form rather than page, the
ImageButton will be placed inside form tag:
HtmlForm form = (HtmlForm)this.FindControl("Form1");
//...
form.Controls.Add(ImageArray[i]);
//...
Hope it's helpful to you.

Hi,
You need to give some part of the source code and the error description.
Then only we can figure out.
