Hi,
How can I sort the root nodes of a treeview according to a integer
stored in their tag property? I want to do that at run time on a
button's click event.

Thank you

AFAIK, the Sorted property of the Treeview only sorts alphabetically, so you
will have to set it to false and sort the treenodes in an array (Array.Sort)
before adding them to the treeview, providing an IComparer that uses the Tag
property of the treenodes.

Thanks for your answer Carlos.

A quick and dirty way, to avoid reload, could also be to use the sort
feature and to make the labels start with *formatted* numbers (if
acceptable) ...

I've used the following to do it: ;-)

Public Class NodesList
        Inherits List(Of TreeNode)

        Public Overloads Sub Sort()
            MyBase.Sort(New NodeTagComparer())
        End Sub
    End Class

    Public Class NodeTagComparer
        Implements IComparer(Of TreeNode)

        Public Function Compare(ByVal node1 As TreeNode, ByVal node2 As
TreeNode) As Integer Implements IComparer(Of TreeNode).Compare
            Return (DirectCast(node1.Tag,
Query).SortOrder.CompareTo(DirectCast(node2.Tag, Query).SortOrder))
        End Function
    End Class

  Dim lstNodes As New AdminSystemLib.NodesList
        For Each n As TreeNode In Me.Nodes
            lstNodes.Add(n)
        Next
        lstNodes.Sort()
