Showing error message

future3839

Hi, I am developing a simple web application in ASP.net. I would like to know in database connection if I face with error how I should show it. do I have to use java script? because unlike desktop application can't use message box.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.SqlClient;
using System.Data;
using System.Data.Sql;
using System.Configuration;

namespace Test.DataAccessLayer
{
public class PersonDataAccess
{

    SqlConnection Conn = new                             SqlConnection(ConfigurationManager.ConnectionStrings\["HostelConnectionString"\].ConnectionString);

    public void insert()
    {
        try
        {
            Conn.Open();
        }
        catch (Exception ex)
        {

????????????????????????????????????????????????????????????????????????????
}
}
}
}

you don't have to use javascript, you can catch the exception and assign ex.message to a label's text. if you still want to use a message box, you do have to use javascript(you can download a exist class)

you can show your message, by using Java script alert Message as

Response.Write("<script>alert('Your Message')</script>");

or you can also use custom error concept to show your message while a error generate follow link Custom Errors in ASP.NET[^]

It is not a good practice, to show exception errors in javascript alert. Better , if you find any exception , show in that page or redirect to some other error page
