Using the DataGridViewProgressColumn class

I am trying referencing the thread "social.msdn.microsoft.com/Forums/en-US/winformsdatacontrols/thread/769ca9d6-1e9d-4d76-8c23-db535b2f19c2" (add your own http://)

I am trying to implement the code, but I cannot seem to assign a value to the progresscolumn cell.

I have tried 2 different ways to add the column to my datagridview object.

The datagridview is populated by a database query, so I have this property:

DataGridView1.AutoGenerateColumns = True

Here is one way that I have added the column: 

               Dim ProgressColumn As New DataGridViewProgressColumn
                ProgressColumn.HeaderText = "Progress"
                ProgressColumn.Name = "Progress"
                ProgressColumn.Visible = True
                DataGridView1.Columns.Add(ProgressColumn)

Now to assign the values after populating the datagridview, I do this:

                For Each dRow As DataGridViewRow In DataGridView1.Rows
                    If dRow.Cells(struct_RM_SelectedColumns.QUANTITY).Value > 0 Then
                        dRow.Cells("Progress").Value = Convert.ToInt32((dRow.Cells(struct_RM_SelectedColumns.PRODUCED).Value / dRow.Cells(struct_RM_SelectedColumns.QUANTITY).Value) * 100)
                    Else
                        dRow.Cells("Progress").Value = 0
                    End If
                Next dRow

In every case, the display shows a label "0%" in the cell.

Can someone show me how to utilize this class properly?

Thanks.
