Hi Richard,

What do you mean by 'folder names'? Could you elaborate more on the issue?

Hi,

Heres some code that may help you in the right direction.
 

        Private Function CreateNewFolder() As RadTreeNode

            Dim newname As String = "Folder"

            newname = CreateFolderName(treeview.Nodes, newname)

            Dim node As New RadTreeNode(newname)

            Return node

        End Function

        Private Function CreateFolderName(ByVal nodes As RadTreeNodeCollection, ByVal baseName As String) As String

            Dim newname As String = baseName

            If Not CheckNameExists(nodes, newname) Then
                Return newname
            End If

            Dim i As Integer = 2
            newname = String.Concat(baseName, " ({0})")
            While (CheckNameExists(nodes, String.Format(newname, i)))
                i += 1
            End While

            Return String.Format(newname, i)

        End Function

        Private Function CheckNameExists(ByVal nodes As RadTreeNodeCollection, ByVal name As String) As Boolean

            For Each node As RadTreeNode In nodes
                If node.Text.ToLower() = name.ToLower() Then
                    Return True
                End If
                If node.Nodes.Count > 0 Then
                    If CheckNameExists(node.Nodes, name) Then
                        Return True
                    End If
                End If
            Next

            Return False

        End Function
