Arithmetic in datagrid columns

Question

Hi I have a datagrid with the columns ItemPrice and ItemQuantity and Total I would like to multiply the ItemPrice and ItemQuantity columns to get the total. I've tried searching around but in vain I know its been done before and I've seen multiple software systems do this. Could someone help me.

You can do it in following way: DataColumn dtc=new DataColumn(Sumtypeof(int)); dtc.Expression=Quantity * Cost; dataTable.Columns.Add(dtc);
