Undo/ Redo functionality in TreeViewAdv using HistoryManager property

Platform: WinForms |
Control: TreeViewAdv |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014

 

The user should get the HistoryManager to use and then the HistoryEnabled property should be set to true.The HistoryManager plays the role in the Undo/Redo actions .

The Undo and Redo functionality of a TreeViewAdv does the following actions:

1. Deleting a node

2. Adding a node

3. Editing node's Text

4. Drag/drop of a node

C#

private void barItem1_Click(object sender, System.EventArgs e)

{

if(this.treeViewAdv1.HistoryManager.CanUndo==true)

{

this.treeViewAdv1.HistoryManager.Undo();

}

}

private void barItem2_Click(object sender, System.EventArgs e)

{

if(this.treeViewAdv1.HistoryManager.CanRedo==true)

{

this.treeViewAdv1.HistoryManager.Redo();

}

}

VB

Private Sub barItem1_Click(ByVal sender As Object, ByVal e As System.EventArgs)

If Me.treeViewAdv1.HistoryManager.CanUndo=True Then

Me.treeViewAdv1.HistoryManager.Undo()

End If

End Sub

Private Sub barItem2_Click(ByVal sender As Object, ByVal e As System.EventArgs)

If Me.treeViewAdv1.HistoryManager.CanRedo=True Then

Me.treeViewAdv1.HistoryManager.Redo()

End If

End Sub
