    For example, we have TreeView with 2 nodes: 1st node is root, 2nd node is child of 1st.
    Every node that is contained in TreeView.Items collection can be easily deleted by:
    1st node can be easily deleted by that code. But 2nd node cannot, because it is not contained in TreeView.Items collection.
    How to delete any subitem of TreeView without going to recursion whole tree?

    Hello M Stolyar,

     You can delete the First_Item's first child by the following code:
    (treeview.Items[0] as RadTreeViewItem).Items.RemoveAt(0);
    This will work when your RadTreeView is not bound. Please let us know if this fits in your scenario.

    Best wishes,
