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 StringAs 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 StringAs 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
