Error Message in ASP.NET Web Forms

Question

I have this code in my page:

 protected void btn_add_Click(object sender, EventArgs e)
 {
      Session["truck_id"] = truck_id;
      Session["user_id"] = user_id;
      Session["usertype"] = usertype;
      if (usertype == "viewer")
      {
          Response.Write("Sorry, you do not have access to this page.");
          Response.StatusCode = 401;
          Response.End();
      }
      Response.Redirect("JobOrderForm.aspx");
}

I have logged in as viewer and the error message is this

How can I change it to Unauthorized Access ?

Answer 1

Change this:

Response.Redirect("JobOrderForm.aspx");

To this:

Response.Redirect("/JobOrderForm.aspx");

/ refers to the root directory. This may help because probably this page and redirected page is not in the same folder.

Answer 2

You have an error on your page. Have you tried debugging it? Set a breakpoint on the first line in the btn_add_Click method and step through to see which line is causing the error.
