The following code example shows how to override the GetEmptyDesignTimeHtml method in a class that is inherited from the MenuDesigner class. The overridden method changes the appearance of a control that is derived from the Menu class at design time. The example generates the markup for a placeholder that includes a message indicating that no menu items are defined for the associated control.
// Generate the design-time markup for the control // when the template is empty.protectedoverridestring GetEmptyDesignTimeHtml()
string noElements = "Contains no menu items.";
} // GetEmptyDesignTimeHtml
