How to set a TreeNodeAdv as non-editable and non-selectable?

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


To set the TreeNodeAdv as non-editable, handle the TreeViewAdv’s BeforeEdit & BeforeSelect events and set the Cancel property to True:


// Suppose the target node is the first node


private void treeViewAdv1_BeforeEdit(object sender, Syncfusion.Windows.Forms.Tools.TreeNodeAdvBeforeEditEventArgs e)


if (e.Node == this.treeViewAdv1.Nodes[0])

e.Cancel = true;


//Non selectable

private void treeViewAdv1_BeforeSelect(object sender, Syncfusion.Windows.Forms.Tools.TreeViewAdvCancelableSelectionEventArgs args)


if (args.SelectedNodes[0] == this.treeViewAdv1.Nodes[0])

args.Cancel = true;



' Suppose the target node is the first node

' NonEditable

Private Sub treeViewAdv1_BeforeEdit(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Tools.TreeNodeAdvBeforeEditEventArgs)

If e.Node = Me.treeViewAdv1.Nodes(0) Then

e.Cancel = True

End If

End Sub

'Non selectable

Private Sub treeViewAdv1_BeforeSelect(ByVal sender As Object, ByVal args As Syncfusion.Windows.Forms.Tools.TreeViewAdvCancelableSelectionEventArgs)

If args.SelectedNodes(0) = Me.treeViewAdv1.Nodes(0) Then

args.Cancel = True

End If

End Sub
