Provides the markup that is used to render the control at design time if the control is empty or if the data source cannot be retrieved.
![]()
The markup used to render the control at design time with an empty data source.
The System.Web.UI.Design.WebControls.BaseDataBoundControlDesigner class retrieves sample data that is used for binding purposes at design time before rendering the control. The empty design-time control renders as a placeholder that contains the type name and control name.
