Move a Node to a Another Parent

This topic will show you how to use the Reposition method to move a node in a WinTree™ from one parent to another.

  1. Before you start writing any code, you should place using/imports directives in your code-behind so you don’t need to always type out a member’s fully qualified name.

In Visual Basic:

Imports Infragistics.Win.UltraWinTree

In C#:

using Infragistics.Win.UltraWinTree;

  1. Place an UltraTree control on a form.

  2. Add the following code to the Load event of the Form in order to populate the tree. This will create two parent nodes (Parent A and Parent B). Parent A will have one child node (Child 1). Parent B will also have one child node (Child 2).

In Visual Basic:

Dim aNode As UltraTreeNode
aNode = Me.UltraTree1.Nodes.Add("Parent A")
aNode.Expanded = True
aNode.Nodes.Add("Child Node 1")
aNode = Me.UltraTree1.Nodes.Add("Parent B")
aNode.Expanded = True
aNode.Nodes.Add("Child Node 2")

In C#:

UltraTreeNode aNode;
aNode = this.ultraTree1.Nodes.Add("Parent A");
aNode.Expanded = true;
aNode.Nodes.Add("Child Node 1");
aNode = this.ultraTree1.Nodes.Add("Parent B");
aNode.Expanded = true;
aNode.Nodes.Add("Child Node 2");

  1. Place a Button on the form.

  2. Go to the Click event of the Button

  3. Add the following code to move Child Node 2 from Parent B to Parent A

In Visual Basic:

Private Sub btnMoveChildNode_Click(ByVal sender As System.Object, _
  ByVal e As System.EventArgs) Handles btnMoveChildNode.Click
	Dim ParentNodeA As UltraTreeNode
	Dim ChildNode As UltraTreeNode
	ChildNode = Me.UltraTree1.GetNodeByKey("Child Node 2")
	ParentNodeA = Me.UltraTree1.GetNodeByKey("Parent A")
	ChildNode.Reposition(ParentNodeA.Nodes)
End Sub

In C#:

private void btnMoveChildNode_Click(object sender, EventArgs e)
{
	UltraTreeNode ParentNodeA;
	UltraTreeNode ChildNode;
	ChildNode = this.ultraTree1.GetNodeByKey("Child Node 2");
	ParentNodeA = this.ultraTree1.GetNodeByKey("Parent A");
	ChildNode.Reposition(ParentNodeA.Nodes);
}

  1. Run the program.

You will see two parent nodes. Parent B has a child node.

  1. Click the button

Child Node 2 will change parents, moving from Parent B to Parent A.

  1. You can also pass in an integer as the a second parameter into the Reposition method to specify a specific index to move the node too.
