The hierarchical path of the view to retrieve.
Return Value
A HierarchicalDataSourceView that represents a single view of the data at the hierarchical level identified by the viewPath parameter.This GetHierarchicalView method provides the default implementation for the HierarchicalDataSourceControl class, which simply returns a null reference (Nothing in Visual Basic). Classes that derive from the HierarchicalDataSourceControl class override this method and provide an implementation to return a strongly typed view that derives from HierarchicalDataSourceView.
The following code example demonstrates how to override the GetHierarchicalView method in a class that extends the HierarchicalDataSourceControl class to return a strongly typed HierarchicalDataSourceView object. This code example is part of a larger example provided for the HierarchicalDataSourceControl class.
