IsDesignMode Property (DrawDesignerObjectEventArgs)

In This Topic

Returns 'true' if the view in the Designer is 'Layout' or 'Layout Preview'. You can control if only the first page of the Designer object has to be drawn in design mode. If 'false' is returned, it means that you are in print mode and drawing has to be made for the complete Designer object.
