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:
  1. Try

  2.             If designmode Then

  3.                 Return

  4.             End If

  5.             AddHandler MainForm.Data.Items.RowChanged, AddressOf ItemRowChanged

  6.             AddHandler MainForm.Data.Items.RowChanging, AddressOf RowChanging

  7.             AddHandler MainForm.Data.Items.RowDeleted, AddressOf RowDeleted

  8.             AddHandler MainForm.Data.Items.RowDeleting, AddressOf RowDeleting

  9.             AddHandler MainForm.Data.Items.ColumnChanged, AddressOf ColumnChanged

  10.             Dim i As Integer = 0

  11.             For Each c As DataColumn In MainForm.Data.Items.Columns

  12.                 ct = New DataGridColoredTextBoxColumn

  13.                 ct.MappingName = c.ColumnName

  14.                 ct.HeaderText = c.ColumnName

  15.                 ct.NullText = ""

  16.                 Select Case c.ColumnName.Trim

  17.  
  18.                     Case "PO No."

  19.                         ct.HeaderText = "PO#"

  20.                         ct.Width = 30

  21.                     Case "Description"

  22.                         ct.HeaderText = "Item Code - Description"

  23.                        ct.Width = 280

  24. '               ... for all columns

  25.                 End Select

  26.                 Try

  27.                     dg.TableStyles(0).GridColumnStyles.Add(ct)

  28.                     If ct.MappingName = "Description" Then

  29.                         ct = New DataGridTextBoxColumn

  30.                         ct.MappingName = "Item Code"

  31.                         ct.HeaderText = "Alpha Code"

  32.                         ct.NullText = ""

  33.                         ct.Width = 100

  34.                         dg.TableStyles(0).GridColumnStyles.Add(ct)

  35.                     End If

  36.                 Catch ex As Exception

  37.                 End Try

  38.                 i += 1

  39. DoNext:

  40.             Next

  41.             dg.DataSource = MainForm.Data

  42.             dg.DataMember = "Items"

  43.          Catch ex As Exception

  44.             PromptMessage(ex.Message, "Error", FrmMessage.ButtonModes.OK, FrmMessage.MessageTypes.ErrorType, ex)

  45.         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...
