How do you acheive this in ASP.NET?

Hi there!

What is the equivlent of the following ASP code in ASP.NET?
please help.

Code:

---

Sub ValidateValue()
      if Condition=False then
    %>
        <SCRIPT LANGUAGE=javascript>
        <!--
              alert("I want to display a msg here & then redirect!");
            //otherwise I would have used Response.Redirect("mainpage.aspx")
            document.location.href="mainpage.asp";
        //-->
      </SCRIPT>
    <%
          Response.End
    end if
End sub

Here's one way, kind of a "hacky" way of doin it but it works.
Code Behind Code:

VB Code:

Protected MyConditional As Literal
Private Sub Page_Load(ByVal sender As System.Object, _
                      ByVal e As System.EventArgs) Handles MyBase.Load
    'Put user code to initialize the page here
    Dim condition As Boolean = False
    If Not condition Then
        MyConditional.Visible = True
    End If
End Sub

Webform code(just the Literal control part):

Code:

---

<asp:Literal
        Runat="server"
        ID="MyConditional"
        Visible="False"
        Text="<script language='javascript'>alert('some message');location.href='http://www.microsoft.com/';</script>" />
