I'm trying to get the value of the IDPair of the row that triggered the event. How do I go about doing that in c#

void WebDatGrid1_RowUpdated(object sender, Infragistics.Web.UI.GridControls.RowUpdatedEventArgs e)

{

    if(e.Exception == null)

    {

        var x = e.RowID.Values; <--- I would like to get the value here to query the SQL database and get values related to that row. Not the Key..

        using(SqlConnection conn = new SqlConnection(connectionstring)

        {

            using(SqlCommand command = conn.CreateCommand())

            {

                command.CommandText= "SELECT blah FROM tblBLAH WHERE PrimaryKey = @x";

                command.Parameters.AddWithValue("@x, x.ToString());

                conn.Open();

                int result = command.ExecuteNonQuery();

                conn.Close();

            }

        }

    }

}
