hi,

i have a DataTable that has a column ("Profit"). What i want is to get the Sum of all the values in this table. I tried to do this in the following manner...

DataTable dsTemp = new DataTable();

dsTemp.Columns.Add("Profit");

DataRow dr = null;

dr = dsTemp.NewRow();
dr["Profit"] = 100;
dsTemp.Rows.Add(dr);

dr = dsTemp.NewRow();
dr["Profit"] = 200;
dsTemp.Rows.Add(dr);

DataView dvTotal = dsTemp.DefaultView;
dvTotal.RowFilter = " SUM ( Profit ) ";

DataTable dt = dvTotal.ToTable();

But i get an error while applying the filter... how can i get the Sum of the Profit column in a variable

thank you...
