Gets the view helper object for the System.Web.UI.IHierarchicalDataSource interface for the specified path.
A System.Web.UI.HierarchicalDataSourceView that represents a single view of the data at the hierarchical level identified by the viewPath parameter.
This HierarchicalDataSourceControl.GetHierarchicalView(string) method provides the default implementation for the System.Web.UI.HierarchicalDataSourceControl class, which simply returns null. Classes that derive from the System.Web.UI.HierarchicalDataSourceControl class override this method and provide an implementation to return a strongly typed view that derives from System.Web.UI.HierarchicalDataSourceView.
