Uncustomising MOSS Pages - Part 2

The other day I wrote about the frustrations of uncustomising a page layout deployed via a feature to the master page gallery. I've since done some additonal hunting and come across the SPFile.RevertContentStream ( ) method to revert a page layout or master page to its original state so feature deployments work again.

Calling this successfully reverts/uncustomises/reghosts the file in question, although I did notice the version history accessible through the master page gallery remains as-is. Nevertheless, a change to the file system .aspx file after running this code is honoured by MOSS.

Here's the code I wrote to encapsulate that call (it's a bit rough but for a one-off excercise does the trick). I simply run this from a console application (which you can download from here).

// Wait for debugger to attach
Console.WriteLine ("Waiting for debugger to attach. Press any key to continue...");
Console.ReadLine ();

const string FILE_PATH = "/_catalogs/masterpage/ThreeColumns.aspx";

using (SPSite site = new SPSite ("http://dev:30000/"))
{
    using (SPWeb web = site.AllWebs ["/"])
    {
        SPFile file = web.GetFile (FILE_PATH);

        Console.WriteLine ("File status before change: " +
                            file.CustomizedPageStatus);

        if (file != null &&
            file.Exists &&
            file.CustomizedPageStatus == SPCustomizedPageStatus.Customized)
        {
            Console.WriteLine ("Reverting file...");

            try
            {
                file.RevertContentStream ();
            }
            catch (Exception e)
            {
                Console.WriteLine (e);
            }

            Console.WriteLine ("File status after change: " +
                                file.CustomizedPageStatus);
        }
        else
        {
            Console.WriteLine ("Unable to retrieve file");
        }
    }
}
