filter date while changing the date from datetimepicker control?

hello,

Am fetching the data from MS Access database in dataGridview.

I have one button to load the data in table after that I want to select the date from datetimepicker and on selection it should dispaly all the records based on the selection in gridview.I tried this code...

private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
        {
             DataView dv = new DataView(dt);

            DateTime startT = new DateTime();
            DateTime endT = new DateTime();
            startT = dateTimePicker1.Value.Date; // Ex: 2014-11-24 12:00:00
            endT = dateTimePicker1.Value.Date.AddDays(1).AddSeconds(-1); // Ex: 2014-11-24 11:59:59
           // dv.RowFilter = string.Format("Select * From CustomerDetails WHERE DATA Between '" + startT + "' AND '" + endT + "'");
            dv.RowFilter = string.Format("BookingDate  '%{0}%'",  dateTimePicker1.Value.ToString());
            dataGridView2.DataSource = dv;
          //bindingSource1.Filter = string.Format("EventDate = #{0}#",dateTimePicker1.Value.ToLongDateString());
        }

Thanks,
