Imports Infragistics.Win.UltraWinTree
This topic will show you how to use the Reposition method to move a node in a WinTree™ from one parent to another.
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;
Place an UltraTree control on a form.
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");
Place a Button on the form.
Go to the Click event of the Button
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); }
Run the program.
You will see two parent nodes. Parent B has a child node.
Click the button
Child Node 2 will change parents, moving from Parent B to Parent A.
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.
