RE: [C#.NET] Re: Index position in a Sorted DataView ?

[Newtz, Brian]

If you just want to highlight the added row, couldn't you just look for it when binding? Keep a Boolean instance variable that states whether or not a row has been added, and based on that value, decide whether or not to color a row. One example could work something like this:

public class MyPage : Page
{
      private bool newRowAdded;
      private object newIdentityColumn;

      protected void Grid_ItemDataBound(...)
      {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                  if (newRowAdded)
                  {
                        DataRowView row = (DataRowView)e.Item.DataItem;

                        if (row["identityColumn"] == newIdentityColumn)
                        {
                              e.Item.CssClass = "colorMe";
                        }
                  }
            }
      }

      protected void Grid_InsertCommand(...)
      {
            newIdentityColumn = InsertRecordIntoDatabase();
            newRowAdded = true;
            Grid.DataSource = RefreshData();
            Grid.DataBind();
      }
}
