Form Validate method not calls usercontrol (inside textbox) validating event regularly

Hi I am having a form with lot of usercontrols,textboxes,etc when i call activemdichild.validate method it seems that some of the validating event of usercontrols not fired but someof them fired? where I am missing is there different between two usercontrols or is there a bug in usercontrol validating event firing Note: all usercontrols have a textbox/maskeditbox inside it Thanks Rajaraman.
