datagridview.SelectedRows returns last row first?

I'm trying to figure out the datagridview, but I'm having trouble
stepping through the selectedrows because the first row I get is the
last row selected (with the heighest index).

For instance if I select 3 rows
jan
feb
mar

Dim TmpRow As DataGridViewRow
For Each TmpRow In dgReports.SelectedRows
msgbox tmprow.index
next tmprow

I'll get 3,2,1 instead of 1,2,3

I don't know if this is by design but it gives me a hard time doing my
stuff right...

Thanks in advance,

Mike

Apparently LIFO (last in, first out) by design.

You can do this:
Dim SelectedRowCount As Integer = _
Me.DataGridView1.Rows.GetRowCount(DataGridViewElementStates.Selected)
If SelectedRowCount > 0 Then
    For i As Integer = SelectedRowCount - 1 To 0 Step -1
    MsgBox(DataGridView1.SelectedRows(i).Cells(1).Value.ToString)

   Next
End If
