Examples
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.
protected override string GetEmptyDesignTimeHtml()
{
string noElements = "Contains no menu items.";
return CreatePlaceHolderDesignTimeHtml(noElements);
} // GetEmptyDesignTimeHtml
' Generate the design-time markup for the control
' when the template is empty.
Protected Overrides Function GetEmptyDesignTimeHtml() As String
Dim noElements As String = "Contains no menu items."
Return CreatePlaceHolderDesignTimeHtml(noElements)
End Function ' GetEmptyDesignTimeHtml
Remarks
The GetEmptyDesignTimeHtml method generates the markup for a placeholder that specifies the Menu control name and a message instructing you to use the collection editor to add items.
