hi i want Set usercontrol size According to the Controls inside it how i can do this? long time ago I used the propretis SizeToContent , but I can not find it right now
@zahra_rajabi, Generally setting width and height properties to "Auto" will automatically sets width and height of a container according to its contents.
Set your main container (width, height) in Usercontrol to Auto to achieve SizeToContent.
* **Remember: DesignWidth and DesignHeight are usefull only on design time
