Central page for error messages

In my ASP.NET C# application, there are many different error messages that I'd like to display.

The way I display my error message is by pop by via:

       Page.ClientScript.RegisterStartupScript(GetType(), "msgbox", "alert('My error message here');", true);
        return;

Since there are many different error messages (some repeated across pages) and I have so many different pages in my application - I'd like to put all the error message on a centralized page and reference to it somehow - so that when I need to change my error message, I only need to change in one page and not across ALL the pages.

What's the best way to do this?

I imagine I need to create a .cs page? And have a different ID for each of the error messages.

This seems like a very simple thing to do but I am a bit lost as to how to start on it.

Can someone advice the best way to do this?

Thanks.

I would add extension method to show the alerts and keep all the exception strings in resource file. then I can call the method as below

USAGE

this.ShowAlert(Resource1.MyException);

EXTENSION METHOD

using System;
using System.Web.UI;

namespace WebApplication1
{
    public static class Extensions
    {
        public static void ShowAlert(this Control control, string message)
        {
            if (!control.Page.ClientScript.IsClientScriptBlockRegistered("msgbox"))
            {
                var script = String.Format("alert('{0}');", message);
                control.Page.ClientScript.RegisterStartupScript(control.Page.GetType(), "msgbox", script, true);
            }
        }
    }
}

Add resource file to your project and enter messages as string entries with meaning full names.

JS method can be defined in
* the Master Page
* in the custom base class inherited by all the pages.

Since you appear to display JavaScript error messages I would create a JS include file and define the JS methods there. That way you can reuse the methods on all pages that include the JS file.
