This is a neat trick to get a tooltip when a user hovers over a row in a gridview. It is very simple and uses standards.

Simply attach something like this to the GridView's RowDataBound event:

protected void GridViewEligibleProducts_RowDataBound(object sender, GridViewRowEventArgs e)
{
   if (e.Row.RowType == DataControlRowType.DataRow)
   {
      // get the row view to be able to access data from the binding object
      DataRowView drv = (DataRowView)e.Row.DataItem;
      // lets me type safe, optional
      ProductsSvc.DSProducts.AgencyEligibleProductsRow thisRow = (ProductsSvc.DSProducts.AgencyEligibleProductsRow)drv.Row;
      // this is the magic to get the tooltip. You could put anything as the 2nd parameter
      e.Row.Attributes.Add("title", (thisRow.IsdescriptionNull() ? "" : thisRow.description));
   }
}
