Changing Master Page on Runtime

Changing Master Page on Runtime

Use following code:

protected void Page_PreInit(object sender, EventArgs e)
{
if (Session["user"] == null)

this.Page.MasterPageFile = "~/MasterPage2.master";

else

this.Page.MasterPageFile = "~/MasterPage1.master";

}

The key here is to put the code in Page_PreInit.
