Answer 1

(dataGridViewFields.DataSource as DataTable).DefaultView.RowFilter = string.Format("START_DATE = '{0}'", dateTimePicker1.Value.ToString("yyyy-MM-dd")); 

または「START_DATE」

string rowFilter = string.Format("[{0}] = '{1}'", columnName, filterValue); 
(myDataGridView.DataSource as DataTable).DefaultView.RowFilter = rowFilter;
