Example
The following sample code illustrates how to change the position of nodes within a tree.

Imports Infragistics.Win.UltraWinTree

Private Sub button17_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button17.Click

    Dim node As UltraTreeNode

    node = Me.ultraTree1.ActiveNode

    If node Is Nothing Then Return

    ' Check if the active node is a root node.
    If node.IsRootLevelNode Then
        ' If the node is the first root level node
        ' make it the last. Otherwise make it the first.
        If node.Index = 0 Then
            node.Reposition(node, NodePosition.Last)
        Else
            node.Reposition(node, NodePosition.First)
        End If
    Else
        ' Reposition the node by appending it to
        ' the root nodes collection
        node.Reposition(Me.ultraTree1.Nodes)

        ' If the root nodes collection is sorted then
        ' re-sort it so that the repositioned node 
        ' is slotted appropriately.
        If Not Me.ultraTree1.Nodes.SortResolved = SortType.None Then
            Me.ultraTree1.RefreshSort(Me.ultraTree1.Nodes, False)
        End If
    End If

End Sub
using Infragistics.Win.UltraWinTree;

private void button17_Click(object sender, System.EventArgs e)
{

	UltraTreeNode node = this.ultraTree1.ActiveNode;

	if ( node == null )
		return;

	// Check if the active node is a root node.
	if ( node.IsRootLevelNode )
	{
		// If the node is the first root level node
		// make it the last. Otherwise make it the first.
		if ( node.Index == 0 )
			node.Reposition( node, NodePosition.Last );
		else
			node.Reposition( node, NodePosition.First );
	}
	else
	{
		// Reposition the node by appending it to
		// the root nodes collection
		node.Reposition( this.ultraTree1.Nodes );

		// If the root nodes collection is sorted then
		// re-sort it so that the repositioned node 
		// is slotted appropriately.
		if ( this.ultraTree1.Nodes.SortResolved != SortType.None )
			this.ultraTree1.RefreshSort(this.ultraTree1.Nodes, false );
