    Hi,

    I have designed custom control, which is inherited from 'System.Windows.Controls.Control'. I have defined the theme for it to change its appearance. in the static constuctor I have added following code.

    Static  MyCustomControl (){
                 DefaultStyleKeyProperty.OverrideMetadata(typeof(MyCustomControl),  
                                      new FrameworkPropertyMetadata(typeof(MyCustomControl)));
    }

    When I drag and drop the control, It does not appear in the designer.
    Can any one tell me, What could be the reason for such behavior?


    Regards,
    Bharath

    Hi BGan

    The best way to debug in this situation is to attach a second instance of Visual Studio to the one in which you are attempting to run your Control on the designer. You will then be able to see whether any debug information is shown when you drag-drop your control.

    The most common sources of issue here are that your control's constructor is failing to run; the method above will assist in identifying why.
