  using CommonDataService;
  namespace Shop
  {
      public partial class Merchant_Login : System.Web.UI.Page
      {
          protected void Page_Load(object sender, EventArgs e)
          {
              if (!IsPostBack)
              {
                  if (HttpContext.Current.Request.Cookies["MerchantLoginCookie"] != null)
                  {
        txtLoginEmail.Text = HttpContext.Current.Request.Cookies["MerchantLoginCookie"]["LoginName"].ToString();
        string Password = HttpContext.Current.Request.Cookies["MerchantLoginCookie"]["Password"].ToString();
        txtPassword.Attributes.Add("value", Password);
                      
  
                  }
                  
              }
              
          }
  
          protected void btnLogin_Click(object sender, EventArgs e)
          {
              try
              {
                  if (chkRememberMe.Checked)
                  {
                      HttpCookie cookie = new HttpCookie("MerchantLoginCookie");
                      cookie.Values.Add("LoginName", txtLoginEmail.Text);
                      cookie.Values.Add("Password", txtPassword.Text);
                      cookie.Expires = DateTime.Now.AddDays(30);
                      Response.Cookies.Add(cookie);
                  }
  
                  User objUser = new User();
                  objUser.EmailID = txtLoginEmail.Text.Trim();
                  objUser.Password = txtPassword.Text.Trim();
                  
                   if (UserService.ValidateEmailID(objUser)==1)
                  {
                      if (objUser.Password == txtPassword.Text.Trim())
                      {
                          Session["Role"] = "Merchant";
                          Session["EmailID"] = txtLoginEmail.Text.Trim();
                          objUser.EmailID = Session["EmailID"].ToString();
                          Session["UserName"] = objUser.UserName;
                          Session["UserID"] = objUser.UserID;
                          Response.Redirect("~/Merchant/Merchant-CreateProfile.aspx", false);
                      }
                      else

                  }
  
                  else
                  {
  
                      WebMsgBox.Show(Messages.strInvalidEmail);

  Please remove my all code and change your section with this code

     if (!IsPostBack)
              {
                  if (HttpContext.Current.Request.Cookies["MerchantLoginCookie"].Value != null)
                  {
        txtLoginEmail.Text = HttpContext.Current.Request.Cookies["MerchantLoginCookie"]["LoginName"].Value;
        string Password = HttpContext.Current.Request.Cookies["MerchantLoginCookie"]["Password"].Value;
        txtPassword.Attributes.Add("value", Password);
                      
  
                  }
