it doesnt run switch Condition

HI

according to below thread I change my SP

Record-is-getting-inserted-twice-in-SQL-Server-using-C-in-ASPNet/

but here it didn't run below code

  int Result =ID;
        switch (Result)
        {

            case 1:
                Session["Message"] = true;
                lblerrorV.Visible = false;
                lblerrorV.Text = "";
                Response.Redirect(Request.Url.AbsoluteUri);
                break;
            case 0:
                //Session["Message1"] = true;

                lblerrorV.Visible = true;
                lblerrorV.Text = "you can enter just 2 item";
                break;
        }

becuse here I define below code

   int ID = Convert.ToInt32(_cmd.ExecuteScalar());
       
        if (ID > 0)
        {
            ViewState["Id"] = ID.ToString();
        }
       

for this ID  always is morethat 1 so it never run Switch Condition now what should I do?

thanks alot
