HierarchicalDataSourceControl::GetHierarchicalView Method

Gets the view helper object for the IHierarchicalDataSource interface for the specified path.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

protected:
virtual HierarchicalDataSourceView^ GetHierarchicalView(
	String^ viewPath
) abstract

Parameters

viewPath
Type: System::String

The hierarchical path of the view to retrieve.

Return Value

Type: System.Web.UI::HierarchicalDataSourceView
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 nullptr. 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.

No code example is currently available or this language may not be supported.
