Question

I keep getting the following error message at compile time: “The name ‘Message’ does not exist in the current context”. All I’m trying to do is pop up a message box. Here are my namespaces declared at the top of my code behind page:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net.Mail;

And here is my code to show a message on a button click:

    protected void EmailAbout_Click(object sender, EventArgs e)
    {
        MailMessage myMessage = new MailMessage();
        myMessage.Subject = "Exception Handling Test";
        myMessage.Body = "Test message body";
        myMessage.From = new MailAddress("[e-mail]");
        myMessage.To.Add(new MailAddress("[e-mail]"));

        SmtpClient mySmtpClient = new SmtpClient();
        mySmtpClient.Send(myMessage);
        Message.Text = "Message sent";
    }

Is this a case of a missing namespace? It seems so basic yet I can’t figure it out? Thanks in advance!

Here is the markup page:

<%@ Page Title="About SalesPro" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeBehind="About.aspx.cs" Inherits="WebApplication2.About" %>

<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
    <h2>
        About, Inc.
    </h2>

    <p>
        Some Stuff here... 
    </p>

    <p>
        <asp:Button ID="EmailAbout" runat="server" Text="Email Information" 
            onclick="EmailAbout_Click" />
    </p>
</asp:Content>

You need the javaScript-function “alert()” 🙂

Try this:

RegisterStartupScript("alertBox1", "<script type='text/javascript'>alert('Message sent');</script>");
