Assembly: System.Design (in system.design.dll)
The HierarchicalDataBoundControl to bind to the design-time data source.
The DataBind method first sets the DataSource property of the HierarchicalDataBoundControl control to reference the design-time data source and sets the DataSourceID property to a null reference (Nothing in Visual Basic). The DataBind calls back to the DataBind method of the control that is derived from the HierarchicalDataBoundControl class to bind to the design-time data source. Finally, it restores the original values of the DataSource and DataSourceID properties.
The dataBoundControl parameter is the control that is derived from the HierarchicalDataBoundControl class that is associated with this designer, or a copy of that control.
