IHierarchicalEnumerable.GetHierarchyData Method (Object)

 

Returns a hierarchical data item for the specified enumerated item.

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

abstract GetHierarchyData : 
        enumeratedItem:Object -> IHierarchyData

Parameters

enumeratedItem
Type: System.Object

The Object for which to return an IHierarchyData.

Return Value

Type: System.Web.UI.IHierarchyData

An IHierarchyData instance that represents the Object passed to the GetHierarchyData method.

Typically, clients that use IHierarchicalEnumerable collections retrieve an IEnumerator object by calling the GetEnumerator method, then iterate through the enumeration and call the GetHierarchyData method on each enumerated item to retrieve an IHierarchyData object.

The following code example demonstrates how an ASP.NET hierarchical data-bound control uses an IHierarchyData object in a recursive data-binding method. The items in an IHierarchicalEnumerable object are enumerated, and for each an IHierarchyData object is retrieved using the GetHierarchyData method. Finally, the HasChildren property is checked to determine whether recursion is necessary. This code example is part of a larger example provided for the HierarchicalDataBoundControl class.
