[2003] Datagrid row coloring

Hi,
This is my first post in here, I will describe my situation. I would like to change the color of a row based on a boolean value. So what I did was, I used a class called DataGridColoredTextBoxColumn which extends DataGridTextBoxColumn. I have a paint method there which is overriden.

In my code, when the control is being loaded:

VB Code:

Try
            If designmode Then
                Return
            End If
            AddHandler MainForm.Data.Items.RowChanged, AddressOf ItemRowChanged
            AddHandler MainForm.Data.Items.RowChanging, AddressOf RowChanging
            AddHandler MainForm.Data.Items.RowDeleted, AddressOf RowDeleted
            AddHandler MainForm.Data.Items.RowDeleting, AddressOf RowDeleting
            AddHandler MainForm.Data.Items.ColumnChanged, AddressOf ColumnChanged
            Dim i As Integer = 0
            For Each c As DataColumn In MainForm.Data.Items.Columns
                ct = New DataGridColoredTextBoxColumn
                ct.MappingName = c.ColumnName
                ct.HeaderText = c.ColumnName
                ct.NullText = ""
                Select Case c.ColumnName.Trim
 
                    Case "PO No."
                        ct.HeaderText = "PO#"
                        ct.Width = 30
                    Case "Description"
                        ct.HeaderText = "Item Code - Description"
                       ct.Width = 280
'               ... for all columns
                End Select
                Try
                    dg.TableStyles(0).GridColumnStyles.Add(ct)
                    If ct.MappingName = "Description" Then
                        ct = New DataGridTextBoxColumn
                        ct.MappingName = "Item Code"
                        ct.HeaderText = "Alpha Code"
                        ct.NullText = ""
                        ct.Width = 100
                        dg.TableStyles(0).GridColumnStyles.Add(ct)
                    End If
                Catch ex As Exception
                End Try
                i += 1
DoNext:
            Next
            dg.DataSource = MainForm.Data
            dg.DataMember = "Items"
         Catch ex As Exception
            PromptMessage(ex.Message, "Error", FrmMessage.ButtonModes.OK, FrmMessage.MessageTypes.ErrorType, ex)
        End Try

I use a listbox which is added to a column of a textbox to add a new row...
The problem with this code is that paint method is called when I add a new row, but I would really like to call it after the row is added. Currently the paint method is being called as soon as I click on the list box which will add a a new row. untill a row is added I cannot retrieve the boolean value which will set the row's color.
Hope that makes sense.
thanks...
