'Usage
Dim instance As LevelHierarchyDataSource
[AspNetHostingPermissionAttribute(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)]
[SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel = true)]
[AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]
[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel = true)]
public class LevelHierarchyDataSource : HierarchicalDataSourceControl,
IDataSource
Remarks
This is the data source that the LevelHierarchyWebPart uses to gather data. It is the intermediary between the consuming LevelHierarchyWebPart and the LevelHierarchyDataSourceView property, which is the object that actually gathers the data. LevelHierarchyDataSource contains similar properties to the LevelHierarchyWebPart and passes these configuration values to the LevelHierarchyDataSourceView.
