The following worked for me:

protected override void OnPreInit(EventArgs e)

{

  base.OnPreInit(e);

  SPWeb myWeb = SPControl.GetContextSite(Context).OpenWeb();

  string strUrl = _webCurrent.ServerRelativeUrl + "/_catalogs/masterpage/my.master";

  this.MasterPageFile = strUrl;

}

Where "my.master" has to be stored in master page gallery of the site.

Correct code:

protected override void OnPreInit(EventArgs e)

{

 base.OnPreInit(e);

 SPWeb myWeb = SPControl.GetContextSite(Context).OpenWeb();

 string strUrl = myWeb.ServerRelativeUrl + "/_catalogs/masterpage/my.master";

 this.MasterPageFile = strUrl;

}

Serge,

Thanks for helping out with this and the few that have commented. I've been playing around with several different ideas on how to handle this(Adding the pages as features, the PreInt Override, User Controls on webpart pages...). I've settled on the suggested PreInt method because of the special case of my implementation of MOSS and development needs.

Thanks again,

Jeff

This seems the be best solution to the problem, but, i don't know how to attach this code to all setting pages, Can you help me?,

Thanks!,

Raul

Me too, how can I attach this code to all the settings pages,

Thanks

I have successfully used this code in my application. But it seems not working with Forms Based Authentication (neither string strUrl = myWeb.ServerRelativeUrl + "/_catalogs/masterpage/default.master"; nor string strUrl = myWeb.ServerRelativeUrl + "/_layouts/application.master";)

I have this entry in web.config file:

<authentication mode="Forms">

<forms loginURL="/_layouts/loginpage/login.aspx" />

</authentication>

and wanted to add master page in the login page. The login page is working fine without master page.

I have created a web application under the layouts\Project folder. When I try to change the master page url in the preinit event, I get an error.

The virtual path '/_catalogs/masterpage/default.master' maps to another application, which is not allowed.

Thanks for your response

I'm with Raul & Rob on this.  How is this code attached to administrative pages ?

Here are the steps to follow: 1. Start a new Web Application using Visual Studio 2005 and go to the Property_Pages

I tried using this approach, however, I keep getting the SharePoint error page with "Unknown Error"

Any ideas?

Looks great guys, but you really shoult dispose that SPWeb object, otherwise you are doing a memory leak, that might take down the entire site.

Use something like:

protected override void OnPreInit(EventArgs e)

{

base.OnPreInit(e);

using( SPWeb myWeb = SPControl.GetContextSite(Context).OpenWeb() ){

string strUrl = myWeb.ServerRelativeUrl + "/_catalogs/masterpage/my.master";

this.MasterPageFile = strUrl;

}

}

Hi All,

I have a problem with customization of the CreatePage.aspx.

When i try to remove 1 control in the page (of course in the copy) i get an error.

Why is it so difficult to make a custom CreatePage.aspx.

I want also change the buttons, so i have created a .cs file. When i have only a html form with 3 new controls, it works fine, but i need the masterpage / navigation etcetera.

Can anybody help me please?

/juniormoss

can you provide a sample source code for the aspx page?

Me too, how can I attach this code to all the settings pages,

Thanks

Hi,

I have tried to follow this idea and the idea suggested by Steve Lineberry... www.thelineberrys.com/.../using-your-sharepoint-sites-master-page-on-all-application-pages-3.html but on certain pages, _layouts/CheckIn.aspx and _layouts/CstWrkflIP.aspx i get the following error.

Unable to validate data.   at System.Web.Configuration.MachineKeySection.GetDecodedData(Byte[] buf, Byte[] modifier, Int32 start, Int32 length, Int32& dataLength)

  at System.Web.UI.ObjectStateFormatter.Deserialize(String inputString)  

This error will not show up unless you enable debug to true in the web.config file and customerrors to off like such.

<compilation batch="false" debug="true">

and

<customErrors mode="Off" />

has anyone else been able to get this to work on all _layouts/*.* pages?

The _layouts/CheckIn.aspx page can be found by trying to ckein a page via the administration pages not SPD and _layouts/CstWrkflIP.aspx can be found by trying to add a workflow, this is the second page of the add workflwo process, approval was the one i was trying to add to the pages library in a site.

Any ideas???

thanks for the GREAT post! Very useful...

Hey Peter Vranich, I figured out the "Unable to validate data" error.  It's the search box.  Check out my new master page and code behind at:  www.thelineberrys.com/.../using-your-sharepoint-sites-master-page-on-all-application-pages-2.html

I would like to do a sime thing as explaine dbelow. Can  you please tell me if it is possible in wss v3?

I want to create my own custom mastser page and all it has is the site actions control (so that I can do edit page create page etc ) (and please i dont want to have any other control that comes in the defualt.master). and text that says hello (The reason I am suing jut hello text is because if i can write hello text I can create my own custom controls). Once I cfreate this page I want to be able to put this in _catalogs/master pages/ folder. Then I would like to create a Helloworld.aspx  layout page that uses   the above created master page and I want to enable creating this Helloworld.aspx using a feature in wss v3.

Any ideas? It looks like it is a reasonable thing to do because then I have complete control and versatility on what i can do on the master pages.

Also why is a site definition restricted to one master page. It would be nice to have a built in feature whic allows us to choose master page at the time of creating a page.

I have a quickie way that worked for me with no code necessary.  If your layouts page has no master associated with it at all, you can simply use the Page Viewer Web Part to display the _layouts page in any SharePoint page.

I get an unknown error when I use forns authentication to active directory - the default site is set to windows.   This was working for a while , but now when I select the extranet site I get unknown error instead of the login box - any suggestions

According to MS you are not supposed to change the application pages or the application master page, you loose MS support should you do this. If you want to change the master page you can only do it the way this article describes. But then you would have to add the code to every application page. Not practical.

If you want to apply this to ALL application pages (which makes sense, I mean why do this any other way) then make a duplicate of the layouts folder, and change the IIS Virtual directory for _layouts to point to the new directory, then you can change the application.master page to your heart’s content.

This works for me, plain and simple:

protected override void OnPreInit(EventArgs e)

{

 base.OnPreInit(e);

 this.MasterPageFile =   SPContext.Current.Web.MasterUrl;

}

very good post , very good idea to add master page from code...

Very Helpful Post.

If worked fantastic for me.

Excellent post.

I do follow what is being said here but still a little confused about where to add the protected override code.

I've fully customised my sharepoint site but need the application pages to be branded correctly.

Where exactly is this code supposed to sit?

detailed info is very much appreciated
