Set Master page dynamically

Question

Hi friends I want to know that can we set Master Page dynamically at runtime? If it is possible then tell me how it will set?

Hi Amit Yes. Set the MasterPageFile property only during the PreInit page event—that is before the runtime begins working on the request (since the rendering of the page with the master page occurs prior to the Init event) protected void Page_PreInit(object sender EventArgs e) { MasterPageFile = simple2.master; } If you try to set the MasterPageFile property in Init or Load event handlers an exception is raised. Note: The Master property represents the current instance of the master page object is a read-only property and can't be set programmatically. The Master property is set by the runtime after loading the content of the file referenced by the MasterPageFile property. The above code needs to add in every page of the site. Instead it is easy enough to add that code to a base page class that you can inherit from for you pages in the site. In case if you do not already have the base page you can use the following web.config settings to have a base class without having to modify the existing aspx pages.
