.NET Forum / Windows Forms / WinForm General / June 2007PropertyDescriptor SetValue not called
I am attempting to create a specialized PropertyDescriptor for the Location property on one of my custom controls. When I attempt to debug it, my breakpoint in GetValue gets hit when I expand the Location property in the property grid to reveal the child properties (X and Y). However, it appears SetValue never gets called. Whether I change the value of the Location property itself, or either of the X or Y child properties; it never hits SetValue. Anyone have any idea why SetValue would never be called? Thanks. Are you using the TypeDescriptionProvider system? I do this all the time and it works just fine for me.

My breakpoint gets hit from the PropertyGrid for GetValue, just never SetValue. I can certainly try the TypeDescriptionProvider and see what happens if you think that'll provide some info. > Are you using the TypeDescriptionProvider system? > [quoted text clipped - 10 lines] >> >> Thanks.
