Setting master pages programmatically for entire application

Question

I know the following will set the master page programmatically in an ASP.NET VB.NET application:

Me.MasterPageFile = "~/masterPage.master"

Is it possible to programmatically set a master page file that would apply to all pages across an application, instead of having to set it for each individual page? I want to be able to retrieve this value from a database in order to set the master page file to use.

If not, is it possible to set more than one master page file in the web.config?

Answer 1

This is what You can do with ASP.NET C#. I didnt test it with VB.

Declare Your own page class and set master page there for all Your pages:

public class MyPage : System.Web.UI.Page
{
    void Page_PreInit(Object sender, EventArgs e)
    {
        this.MasterPageFile = "MasterPage.master";
    }
}

Inherit from Your own page class for each page that You create:

public partial class _Default : MyPage
{
}
