My problem is that the required field validators in the edit form of the grid are not being fired or at least the validation do not stop the postback of the command, because I can see that Page.IsValid property is false when debugging myGrid_ItemCommand. Do you have an idea of what could be happening. my understanding is that there should not be a postback when the form is empty. I have tried using validation groups, removing the radPanel and the RadInputManager but still no luck. I know that I could stop the execution of the command using something like this:
if(!Page.IsValid)
{
e.Cencled = true;
return;
}
but I want to avoid the post back.
I'm using RadControls for ASPNET AJAX Q1 2009 (2009.1.527.35)
Thank you for your help!!!
