Hi. My situation is:
in a gridview's each row, I have a button which by click will popup a form in which is a fileupload control and a validation control to check file extention.
when I first time click a button, everything will work fine, then after I upload a file, the popup form will disappear. it just what I want.
then, when I click another button, it popup again and the validation is fired. I thought that it is the viewstate cause the validation, and I disabled viewstate of the fileupload control and it's container ( a panel control) but the problem still the same
My question is what can I do to don't fire the validation when the popup alive again?
Thanks
