Use the TreeNodeBindingCollection.RemoveAt(int) method to remove the System.Web.UI.WebControls.TreeNodeBinding object located at index from a System.Web.UI.WebControls.TreeNodeBindingCollection object. All items that follow that node are then moved up to fill the vacant position. The indexes of the moved items are also updated.

As an alternative, you can remove a specific System.Web.UI.WebControls.TreeNodeBinding object by using the TreeNodeBindingCollection.Remove(TreeNodeBinding) method. You can also remove every node in the collection by using the System.Web.UI.StateManagedCollection.Clear method.
