Problem sorting list view [UnResolved]

My sorting function for my list view will sort a column. There is no problem with that. The problem comes up when I clear out all the list view items and start adding new items.

As soon as I add an item I get this error

"An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in system.windows.forms.dll

Additional information: Specified argument was out of the range of valid values."

which happens in this line

VB Code:

returnVal = [String].Compare(CType(x, _
                        ListViewItem).SubItems(col).Text, _
                        CType(y, ListViewItem).SubItems(col).Text)

my class for the listview item comparer is this

VB Code:

Class ListViewItemComparer
    Implements IComparer
    Private col As Integer
    Private order As SortOrder
 
    Public Sub New()
        col = 0
        order = SortOrder.Ascending
    End Sub
 
    Public Sub New(ByVal column As Integer, ByVal order As SortOrder)
        col = column
        Me.order = order
    End Sub
 
    Public Function Compare(ByVal x As Object, ByVal y As Object) As Integer _
                        Implements System.Collections.IComparer.Compare
 
        'Try
        Dim returnVal As Integer = -1
        returnVal = [String].Compare(CType(x, _
                        ListViewItem).SubItems(col).Text, _
                        CType(y, ListViewItem).SubItems(col).Text)
        ' Determine whether the sort order is descending.
        If order = SortOrder.Descending Then
            ' Invert the value returned by String.Compare.
            returnVal *= -1
        End If
 
 
 
        Return returnVal
        'Catch
        'End Try
    End Function
End Class

Here is the code inside my Listviews Column Click Event

VB Code:

' Determine whether the column is the same as the last column clicked.
        If e.Column <> sortColumn Then
            ' Set the sort column to the new column.
            sortColumn = e.Column
            ' Set the sort order to ascending by default.
            lvResults.Sorting = SortOrder.Ascending
        Else
            ' Determine what the last sort order was and change it.
            If lvResults.Sorting = SortOrder.Ascending Then
                lvResults.Sorting = SortOrder.Descending
            Else
                lvResults.Sorting = SortOrder.Ascending
            End If
        End If
        ' Call the sort method to manually sort.
        lvResults.Sort()
        ' Set the ListViewItemSorter property to a new ListViewItemComparer
        ' object.
        lvResults.ListViewItemSorter = New ListViewItemComparer(e.Column, lvResults.Sorting)
        If lvResults.Items.Count > 1 Then
            'some varibles that are created from the drawing.color class
            Dim white As System.Drawing.Color
            Dim grey As System.Drawing.Color
            white = Color.White
            grey = Color.LightGray
            'paint the rows Hurray took awhile to figure that one out
 
            PaintAlternatingBackColor(lvResults, white, grey)
        End If

What I'd like to do is every time I add an item to the list view (which is when you run a search) is make it so the program will no attempt to sort the column until the user clicks on the column.

For some reason it tries to sort anything that is added to the list view automaticly. How can I prevent it from doing this to me ?

I fixed it , changing the sorting propertty to none before new search is run solved the problem.

DUUUUH

I'm still having this problem. How can I change that function thats crashing on my to include a if statement to check to make sure there is at least 2 items in the list view before it attempts to sort?
