set masterpage file dynamically- c#

The only way it works is when I change it manually to:

<%@ Page Title="" Language="C#"  AutoEventWireup="false"    MasterPageFile="~/MasterPage.master" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

or 

<%@ Page Title="" Language="C#"  AutoEventWireup="false"    MasterPageFile="~/MasterPage2.master" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

Open in new window

To do this dynamically, from the a control on the master page, I open a page using:

Response.Redirect("Default2.aspx", false); //<-- have tried true also

and in the Default2.aspx.cs I have:

public partial class Default2 : System.Web.UI.Page
{
   protected void Page_Load(object sender, EventArgs e)
   {
       
    }
    protected void Page_Preint(object sender, EventArgs e)
    {
        MasterPage myMaster=Master as MasterPage;
      Label lbl = (Label)myMaster.FindControl("lblCmdOpt");
        if (lbl.Text == "f123")
        {
        MasterPageFile =  "~//MasterPage.master";
       }
        else
       {
            MasterPageFile = "~//MasterPage2.master";
        }
    }
}

Open in new window

But the problem is Page_Preint doesn't fire.

Question: How can I change the masterPage dynamically?

Thank you.

Hi Dan,

I have AutoEventWireup="false" and also have kept MasterPageFile="~/MasterPage.master" because removing it doesn't compile:

<%@ Page Title="" Language="C#"  AutoEventWireup="false"    MasterPageFile="~/MasterPage.master" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

Open in new window

I added breaks at line 3 and 9 to see if the code is firing.

Line 3 is firing when the application first lunched.

But although Response.Redirect("Default2.aspx",false); fires, line 9 never does.

Question: What else I should do for the line 9 fires?

Thank you,

Mike
