Hi Richard,
You can do this by inheriting DataGridTextBoxColumn and overriding the Paint
method to conditionally
change the cell format. Here is an example that colors cells based on their
value:
Public Class DataGridColoredTextBoxColumn
Inherits DataGridTextBoxColumn
Public Sub New()
End Sub
Protected Overloads Overrides Sub Paint(ByVal g As Graphics, ByVal
bounds As Rectangle, ByVal source As CurrencyManager, ByVal rowNum As
Integer, ByVal backBrush As Brush, ByVal foreBrush As Brush, ByVal
alignToRight As Boolean)
Try
Dim o As Object
o = Me.GetColumnValueAtRow(source, rowNum)
If (Not (o) Is Nothing) Then
Dim c As Char
c = CType(o, String).Substring(0, 1)
If (c = "Test") Then
backBrush = new SolidBrush(Color.Red);
foreBrush= new SolidBrush(Color.White);
End If
End If
Catch ex As Exception
' empty catch
Finally
MyBase.Paint(g, bounds, source, rowNum, backBrush,
foreBrush, alignToRight)
End Try
End Sub
End Class
Hope this helps.
Thanks

I know that you can format a grid and its columns using DataGridTableStyle
and DataGridTextBoxColumn in VB.NET. But can you change the format of the
individual rows, or even cells, to something other than the default?
For instance, I have a datagrid displaying a list of products in stock. I
want to highlight the products in red if the product is out of stock. How
should I implement this?
Please let me know if you have the answer. Thanks.
