Parameters

• key
  Type: Microsoft.SharePoint.Administration.SPWebApplication.SPCustomPage

  The application page to replace with the specified custom application page.

• newValue
  Type: System.String

  The location of the custom application page. This must start with “/_layouts/”. To remove the mapping to the custom page, set the value to a null reference (Nothing in Visual Basic).

Examples

The following code sample shows how to update the mapping from the default AccessDenied.aspx application page to a custom application page and display it to the console. The original application page is restored at the end.

using Microsoft.SharePoint;
using Microsoft.SharePoint.Administration;

namespace MapCustomAppPage
{
    class Program
    {
        static void Main(string[] args)
        {
            using (SPSite site = new SPSite("http://MyServer"))
            {
                //Get a reference to the web application.
                SPWebApplication webApp = site.WebApplication;

                //Update AccessDenied application page to AxsDnd.aspx.
                webApp.UpdateMappedPage(SPWebApplication.SPCustomPage.AccessDenied, "/_layouts/SubFolder/AxsDnd.aspx");
                webApp.Update();

                //Output the newly assigned application page.
                Console.Out.WriteLine(webApp.GetMappedPage(SPWebApplication.SPCustomPage.AccessDenied));

                //Reset the mapping to the default application page.
                webApp.UpdateMappedPage(SPWebApplication.SPCustomPage.AccessDenied, null);
                webApp.Update();

                Console.Out.WriteLine("Press any key...");
