how to bind the value to gridview

i have a datatable

DataTable dtBindGrid = new DataTable();

    dtBindGrid = serviceobj.SelectExamTimeTable(txtSchoolName.Text, txtBranchName.Text, txtClass.Text, txtExamName.Text);


    foreach (DataRow row in dtBindGrid.Rows)
    {

       strgetday=  row["Day"].ToString();
       strgetdate = row["Date"].ToString();

       DatedTime = Convert.ToDateTime(row["Time"].ToString());
      strgettime = DatedTime.ToString("t");

       strgetsubject = row["Subject"].ToString();
      strgetduration = row["Duration"].ToString();
      strgetsession = row["Session"].ToString();
      strgetminmark = row["MinMarks"].ToString();
      strgetmaxmark = row["MaxMarks"].ToString();

   //  dtBindGrid.Rows.Add(row);
    }



    GrdExamTimeTable.DataSource = dtBindGrid.DefaultView;
    GrdExamTimeTable.DataBind();

this datatable will return me some values like day,date,time,duration,subject,..

here im getting each value in string bec to convert the Time as 9.00am or 9.00pm

DatedTime = Convert.ToDateTime(row["Time"].ToString()); strgettime = DatedTime.ToString("t");

.... how to bind this converted value to my gridview.
