Dear all
I use a inherit controls to inherit a mustinherited control, however it can not be showed in ide with the error:
An error occurred while loading the document, Fix the error, and then try loading the document again. The error message follows: The designer must create an instance of type , but it can't because the type is declared as abstract.
