HierarchicalDataSourceView::Select Method
Gets a list of all the data items in the view.
Assembly: System.Web (in System.Web.dll)
Return Value
Type: System.Web.UI::IHierarchicalEnumerableAn IHierarchicalEnumerable collection of data items.
The Select method returns an IHierarchicalEnumerable collection of data items in the current view. You can call the GetEnumerator method to get an IEnumerator object and iterate through the collection of data items.
The following code example demonstrates how to override the Select method in a class that derives from the HierarchicalDataSourceView class to retrieve hierarchical FileSystemInfo data from a file system. For security purposes, file system information is displayed only if the data source control is being used in a localhost, authenticated scenario, and only starts with the virtual directory that the Web Forms page using the data source control resides in. Otherwise, the viewPath parameter passed to the constructor of the view object might be used to create a view based on the current file system path. This code example is part of a larger example provided for the HierarchicalDataSourceControl class.
