i have a table Exams and column examHours of int type. it saves the exam completion hours in minutes(e.g 70).

now this value should decrease in every second and updated value will be visible in a label.

what i am doing is...

public partial class GiveExam : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            string strtitle = Request.QueryString["title"];
            string examID = Request.QueryString["exmid"];
            LblExmNm.Text = strtitle;
            SqlCommand cmd = new SqlCommand("select distinct examHours,totalQn from dbo.Exams where examID=@examID");
            cmd.Parameters.AddWithValue("@examID", examID);
            DataSet ds = GlobalConnect.ExecuteDataSet(cmd);
            if (ds != null && ds.Tables.Count > 0 )
            {
                lblTotQns.Text = ds.Tables[0].Rows[0][1].ToString();
                int TotalTime = Convert.ToInt32( ds.Tables[0].Rows[0][1].ToString());//here value is 70
            }
