I'm having trouble trying to show a message (from the server side to the client side) before I do a response.redirect to another page.
The thing is that I put the code to show the message but it never appears in the page, it does the redirect but it doesn't show the message.

The code I'm using to show the message is this:

sScript.AppendLine("<script type=""text/javascript"">")
sScript.AppendLine("  alert('La operacion no ha sido exitosa');")
ScriptManager.RegisterStartupScript(Me, Me.GetType, "AlertaJS", sScript.ToString, False)

sScript is a stringbuilder

Is there any other way to showing messages from server side to client side?


When you use a Response.Redirect ASP.NET adds header to issue a 302, object moved. Since the browser processes the header, and requests the new url, before the page actually loads this method won't work for you.

You can add JavaScript after the alert such as

window.location.href = 'http://my new location';

Sorry Amir,just find it now
place your message in a page with this header :
<meta http-equiv="refresh" content="5;url=Default.aspx" />
and redirect them to this page.
This header will redirect them to the "default.aspx" after 5 seconds but before that they can see your message.

example :

<html xmlns="">
<head runat="server">
    <title>Access Denied</title>
    <meta http-equiv="refresh" content="5;url=Default.aspx" />
    <link rel="Stylesheet" type="text/css" href="default.css" />
<body dir="rtl">
    <form id="form1" runat="server">
    <div class="error">
        <img alt="error" src="images\cross1.png" width=50 height=50 />
       access denied.</div>
        <br />
        <br />
        <a href="Default.aspx">go to home page</a>

So your solution would involve create a new page for each message that may need to be displayed, redirecting uses there, then on to yet another page? Do you see any problems with this?

It is just a clue. Having a dynamic part for messages isn't a complicated problem and is very easy to solve. Isn't it ?
