[RESOLVED] login problem

hi i have this code to do some action if button clicked for 3 times. Just like if users enters a wrong password for 3 times the account is blocked

this the code where LoginAttempt is set default value to 0

if(user.LoginAttempt < 3){

      if(!login)
      {
          user.LoginAttempt = user.LoginAttempt + 1;
      }
      else
      {
          user.LoginAttempt = 0;
      }
}
else
{
  //do something
}

here is my login code how to make work with the first code

 var result = _datamoel.Users.FirstOrDefault(i => i.UserName.Equals(txtuser.Text) && i.Password.Equals(txtpass.Text));
            if (result != null)
            {

                result.UserTypeReference.Load();
                Session["Username"] = txtuser.Text;
                if (result.UserType.TypeName.Equals("clerk"))
                Response.Redirect("clerk/clerkPage.aspx");
                          
            }
           
            else

                lblmsgw.Text = "UserName/Passsword Not Correct! Please Change UserName/Passsword and Try again";

If you are using Asp.NET Membership provider you can configure the provider to have login attempts,

maxInvalidPasswordAttempts="3"

{any attempt number}.For more see
Login Attempts

You can store the number of attempts in a Session variable say Session["Attempts"]. if the value exceeds 3 then show an error message.
