Write the following code in the DataGrid ItemDataBind event:
INT SUM = 0;
IF (E.Item.ItemIndex> 0)
{
Sum = int.parse (E.Item.cells (3) .text);
}
Else
IF (E.Item.ItemType == ListItemType.footer)
{
E.Item.cells [0] .Text = "Total:";
E.Item.cells [1] .Text = Sum.toString ();
E.Item.cells [2] .Text = "average:";
E.Item.cells [3] .Text = ((int)). Tostring ();
}
// Due to the simple page code, it is not written.
