Sort the rows of a datagridview but not the last two

Question

Hi,
with this code, the last row isn't sorted:
Protected Overrides Sub OnSortCompare(ByVal e As System.Windows.Forms.DataGridViewSortCompareEventArgs)
MyBase.OnSortCompare(e)
If e.RowIndex1 = Me.RowCount - 1 Then e.Handled = True
If e.RowIndex2 = Me.RowCount - 1 Then e.Handled = True
End Sub
How can I expand this code to do not sort the second last row too?
This doesn't work:
Protected Overrides Sub OnSortCompare(ByVal e As System.Windows.Forms.DataGridViewSortCompareEventArgs)
MyBase.OnSortCompare(e)
If e.RowIndex1 = Me.RowCount - 1 Then e.Handled = True
If e.RowIndex2 = Me.RowCount - 1 Then e.Handled = True
If e.RowIndex1 = Me.RowCount - 2 Then e.Handled = True
If e.RowIndex2 = Me.RowCount - 2 Then e.Handled = True
End Sub

Hi DerStauner,
I have no idea about what do you mean “But I would like to fix the last two row”.
 My code seems sort correct all of the data in the datagridview. Would you like to share a sample about this?
Please pay attention that the sort method of ID is according to the string, so”10” will be before than “2”. If you want to compare the ID as integer, you need to change to your code to compare with integer instead of string.
Here is a sample (change the OnSortCompare method with following code):
Protected Overrides Sub OnSortCompare(ByVal e As System.Windows.Forms.DataGridViewSortCompareEventArgs)
MyBase.OnSortCompare(e)
'If e.RowIndex1 = Me.RowCount - 1 Then e.Handled = True
Dim a As Integer = CInt(e.CellValue1.ToString())
Dim b As Integer = CInt(e.CellValue2.ToString())
e.SortResult = a.CompareTo(b)
e.Handled = True
If e.RowIndex2 = Me.RowCount - 1 Then e.Handled = True
End Sub
Hope this helps.
