In fact this is not supported and it will be never supported, no one need such a feature except you? — King King, Sep 15 '13 at 18:00

for that you need to understand what are you putting in the condition. read here on Control.DesignMode Property:

Gets a value indicating whether a control is being used on a design surface.

The DesignMode property will be set to True when you are editing your winform page in Visual Studio. For example if you create a user control you could show a user control based on dummy data during design-time and at run-time generate a user control based on the provided data

i don't think you can push a button in designer time so this code does nothing i'm afraid
