Treeview Sort and Group Nodes

Hello All,

I have Extended treeview, in order to have Multiselect.
I also have Extended three different types of nodes Group, Project and ProjectDirectory from Treenode.

The Hirarchy is like Bellow

+Group1
+ ProjectNodeA
-ProjectDirectory Node 1
Group2
+ ProjectNodeB
-ProjectDirectory Node 1


I want to Sort the Group and ProjectNodes and then Display the GroupNodes first and then Project Nodes

Current solution i have is

Code:

---

Private Sub SortNodes()
        Dim pnodes As New List(Of KurmaahTreeNode)
        Dim gnodes As New List(Of KurmaahTreeNode)

        For Each nnode As KurmaahTreeNode In Me.TreeView.Nodes
            If nnode.NodeType = TypeOfNode.GroupNode Then
                gnodes.Add(nnode.Clone())
            ElseIf nnode.NodeType = TypeOfNode.ProjectNode Then
                pnodes.Add(nnode.Clone())
            End If
        Next

        Dim tempparray() As KurmaahTreeNode = Nothing
        Dim tempgarray() As KurmaahTreeNode = Nothing

        Array.Resize(tempparray, pnodes.Count)
        Array.Resize(tempgarray, gnodes.Count)

        tempparray = pnodes.ToArray()
        tempgarray = gnodes.ToArray()

        Try
            Array.Sort(tempparray, New TreeNodeComparer)
            Array.Sort(tempgarray, New TreeNodeComparer)
        Catch ex As Exception
            Console.WriteLine(ex.Message)
        End Try
       

        Me.TreeView.Nodes.Clear()

        Me.TreeView.Nodes.AddRange(tempgarray)
        Me.TreeView.Nodes.AddRange(tempparray)
    End Sub

---

But the problem is that when i try to Call the function from AfterLabelEdit, weird behavior is observed

Is there a better way to do this ??
Can anyone guide me on this thanks

what exactly is happening?

The Sort method runs infinitly and then ERROR pops up

Context 0x4aa77a0' is disconnected. Releasing the interfaces from the current context (context 0x4aa7630).This may cause corruption or data loss. To avoid this problem, please ensure that all contexts/apartments stay alive until the applicationis completely done with the RuntimeCallableWrappers that represent COM components that liveinside them.
