How do you dynamically assign a Master Page?

Is it possible to 开发者_开发知识库assign a Master Page dynamically?

Assign the master page in PreInit of the page whos MasterPage you wish to dynamically set:

protected void Page_PreInit(Object sender, EventArgs e)
{
    this.MasterPageFile = "~/YourMaster.master";
}

You can assign the master page during the Page_PreInit by using the MasterPageFile property.

Me.MasterPageFile = "~/masterpage.master"
