There is no developer advantage to creating your own designer derived from UserControlDesigner. To enhance the design-time experience for a custom control, derive your control from CompositeControl and your designer from CompositeControlDesigner. In that case, you would not use an .ascx file for your ASP.NET markup.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
