Question for TreeViewAdv

Hi, I Wrote a very simple program to use TreeViewAdv. If you right click on the Top Level Tree, It will pop up context menu which allow you add child. My issues is after I successfully add child to top level, I can''t select any tree items. Attached is my sample program, please take a look at it. Thanks a lot. --Shuyang He test_6980.zip

Hi Shuyang, After having further investigated this code, it appears to be a shortcoming in our TreeViewAdv control. I have notified the development team in this regard, and will update you as soon as I have more information available. For now, you could use the PopupMenu control instead of the .Net ContextMenu as a workaround. '' set the TreeViewAdv as the target control of the PopupMenu Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.PopupMenusManager1.SetXPContextMenu(Me.TreeViewAdv1, Me.PopupMenu1) End Sub '' Before displaying the menu, check if its the first node Private Sub PopupMenu1_BeforePopup(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.CancelMouseEventArgs) Handles PopupMenu1.BeforePopup Dim root As TreeNodeAdv = Me.TreeViewAdv1.Root.Nodes(0) Dim clickPoint As Point = Me.TreeViewAdv1.PointToClient(Control.MousePosition) Dim clickNode As TreeNodeAdv = Me.TreeViewAdv1.PointToNode(clickPoint) If (root Is clickNode) Then '' display popupmenu Else e.Cancel = True End If End Sub '' Insert a new node on the first BarItem being clicked Private Sub BarItem1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BarItem1.Click Dim root As TreeNodeAdv = Me.TreeViewAdv1.Root.Nodes.Item(0) Dim newNode As TreeNodeAdv = New TreeNodeAdv("TestCat") root.Nodes.Insert(0, newNode) End Sub I have modified your earlier sample accordingly and have attached it here. Let me know if this works for you. We appreciate your feedback, and thanks for choosing Syncfusion products. Regards, Guru Patwal Syncfusion, Inc.
