Hi Ernesto,

I took a look through your sample, but I don't see what is doing the AutoLoad? or what is triggering the PostBack?

Does the issue still occur if you replace the GridPanel with a Panel?

More information required.

[SOLVED] Double Postback issue

Hello,

I have a simple ASPX page called using "Autoload" into a Panel control. This parent page passes a Querystring value to it. But for some reason it does a double Postback (not all the time). Is there something I need to do to prevent this.
Please see HTML and code-behind bellow.

Any ideas will be appreciated.
