Get Child Items of a Parent

[Sharada]

Hi ,

How I can get the all Child Items of a Parent.

we are able to find the parent RadTreeListViewRow but could not find child row.

we tried below code but it is not working for us. 
  <>var Child = ((currentControl as Telerik.Windows.Controls.TreeListView.TreeListViewRow).ParentRow as Telerik.Windows.Controls.TreeListView.TreeListViewRow).ChildrenOfType<TreeListViewRow>();

Please suggest how to find all child row given a parent.
