Changing background color of individual datagrid cells

To change the background of a cell in a WEB datagrid, it is best to do this at
the ItemDataBound event. At that point just add an attribute to the cell

Somthing like this will do:
private void dg_ItemDataBound(object sender, DataGridItemEventArgs e)
{
  if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
  {
   DataRowView row = (DataRowView)e.Item.DataItem;
   if(row["FieldName"].ToString == "Your Value")
   {
     e.Item.Cells[iColNum].Attributes.Add("style","your style");
   }
  }
}

The key is to override the Paint method on the DataGridTextBoxColumn. First you
need to create your own class that inherits from DataGridTextBoxColumn. override
the paint method and then you are set.

Hope that this helps

Thanks for the link.  I checked it out.

Its using C# Windows forms and not a C# web application...  I couldnt seem to get the code working in a Web App... 

Is it possible to use similar code to this in a web app or would it be totally different?
