How to Create a Message box in ASP.Net

[Mudassir]

people face lot of problems in creating message boxes like in desktop applications in asp.net, there are lot of ways of calling javascript alerts, but here i would explain how to generate a message box in asp.net..
for that , create a class and name it Messages.cs in App_Code. the class will have a single method to generate the message box like as follows

 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
 
/// <summary>
/// Summary description for Messages
/// </summary>
public class Messages
{
    public Messages()
    {
        //
        // TODO: Add constructor logic here
        //
    }
 
 
    public void CreateMessageAlert(string strMessage)
    {
        Guid guidKey = Guid.NewGuid();
        Page pg = (Page)HttpContext.Current.Handler;
        string strScript = "alert('" + strMessage + "');";
        pg.ClientScript.RegisterStartupScript(pg.GetType(), guidKey.ToString(), strScript, true);
    }
}
 
 

now in your page where ever you want to display an OK message box , you can call like this

Messages myMsg=new Messages(); // create the object 
myMsg.CreateMessageAlert("Your Message Here");
