Hi,
I am Asha Bhatt.
I am making simple form in asp.net and validation in java script.

we this is my .aspx.cs code

using System.Data.SqlClient;

public partial class InterviewSet : System.Web.UI.Page
{
    string scon = "Data Source=RBWORKSTATION2\\SQLEXPRESS;Initial Catalog=onlineexamdb;Integrated Security=True;MultipleActiveResultSets=true";
   //SqlDataAdapter da;
    SqlCommand cmd;
   // DataSet ds;
    SqlDataReader readsid;
    public string sid, uid;
    public string time;
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            TimeCheckBox.Checked = false;
        }
        
    }
    protected void AddButton_Click(object sender, EventArgs e)
    {

        if (Convert.ToInt32((Convert.ToInt32(Easyqus.Text) * 100) / 100) + ((Convert.ToInt32(Mediumqus.Text) * 100) / 100) + ((Convert.ToInt32(Hardqus.Text) * 100) / 100) != 100)
        {
            ErrorAddTextLabel.Visible = true;
        }
        else
        {
            ErrorAddTextLabel.Visible = false;
        }
        

        SqlConnection con = new SqlConnection(scon);
        try
        {
            con.Open();
            cmd = new SqlCommand("select SubID from SubjectInfo where SubID = (select MAX(SubID) from SubjectInfo )", con);
            readsid = cmd.ExecuteReader();
            while (readsid.Read())
            {
                sid = readsid[0].ToString();
                //  Response.Write(sid);
            }
            time = DateTime.Now.ToString("T");
            cmd = new SqlCommand("insert into TestInfo values(' " + Testname.Text + " '," + NoQus.Text + " , " + sid + " , " + Easyqus.Text + " , " + Mediumqus.Text + " , " + Hardqus.Text + " , " + Passmarks.Text + " , ' " + TimeTextBox.Text + " ')", con);
            cmd.ExecuteScalar();
            Response.Write("<script>alert('Your record is insert successfuly')</script>");
        }
        catch (Exception ex)
        {
            con.Close();
          //  Response.Write(ex.Message);
        }
 protected void TimeCheckBox_CheckedChanged(object sender, EventArgs e)
    {
        if (TimeCheckBox.Checked)
        {
            TimeTextBox.Visible = true;
            if (TimeTextBox.Text.Length > 59)
            {
                // Response.Write("<script>alert('Test Time can not be blank')</script>");
               // TimeErrorLabel.Visible = true;
                RangeValidator1.Visible = true;
            }
            
        }
        else
        {
            TimeTextBox.Visible = false;
            TimeErrorLabel.Visible = false;
        }
    }
