Hey everyone.

I have a DataTable which is bind to dataGridview in my code.

When I get datas from database, the gridview works fine. it fills with data.
What I want to do is getting the index(actually the value of the Primary key) of the of the specified row.

How can I do it?

                id = (from DataRow dr in dt.Rows
                      where (string)dr["Description"] == rowvalue
                      select (int)dr["Id"]).FirstOrDefault();
            }
            catch(Exception ex)
