SharePoint 2007: using ASP.NET server side code in your pages

Remember the problems you had in SharePoint 2003 pages because it was not possible to plug in a simple piece of server side script in your pages? That you always had to write custom controls to accomplish this? Those times could be over, as longs as you approach this with great care.

In the web.config file in the SharePoint virtual directory contains the following section:

    <SafeMode MaxControls="200" CallStack="false" DirectFileDependencies="10" TotalFileDependencies="50" AllowPageLevelTrace="false">

By default the node <PageParserPaths> is empty. You can add <PageParserPath> nodes to specify the virtual paths where you want to allow server side scripts:

        <PageParserPath VirtualPath="/pages/*" CompilationMode="Always" AllowServerSideScript="true" IncludeSubFolders="true"/>

Where CompilationMode is one of the following values:

Always The page should always be compiled (default value)
Auto ASP.NET will not compile the page, if possible. 
Never The page or control should never be dynamically compiled.

I assume that the AllowServerSideScript and IncludeSubFolders flags speak for themselves.

Be careful with the virtual paths you specify in your PageParserPaths. Anyone that can modify or add a page to the virtual path can insert code that will be executed server side with no restrictions.

A good location to specify as a PageParserPath is the location where you store your masterpages, for example /_catalogs/masterpage. You can now add server side script to your masterpages, which makes it available in all pages using this masterpage.

        <PageParserPath VirtualPath="/_layouts/masterpage/*" CompilationMode="Always" AllowServerSideScript="true" IncludeSubFolders="true"/>

There is no documentation available on this functionality. I found two references in the Microsoft SharePoint documentation that handled with variations: and

Maurice Prather also describes the PageParserPath functionality in this blog post.

Thanks to Stramit for pointing me in the right direction in this blog post on SharePoint navigation.


  • Dear Oever
    I read almost all of your blog, good articles, I also very interested about Macaw skinner tool, are you have any plan for continuing it for WSS 3?

  • Hi Farvashan, I have a new version ready that runs on .Net 2.0, should work for WSS3. Waiting for codeplex project to release it.

  • ok, I'm waiting for your release, also it's nice your picture on the home page ;) can you tell me how can I do same( I use community server 2 on sharepointblogs ), also I linked you, be happy you and your son.

  • @tuan anh: I'm afraid you have to do some studying yourself;-) Pick up a few books on programming, install Visual Studio 2005 and start rolling...

    If you have very specific needs and are willing to pay for the hours needed for implementation, yuo can always let me know;-)

  • Hello,

    had this problem too - code block isnt allowed in my in sharepoint sites masterpage. Solved it with the - setting in web.config. (great)

    Have another probelm aswell. Have assigned my topnavigation sharepoint:aspmenu control to a xmldatasource - works great - but when I try to hook an MenuItemDataBound event to that control I get a message saying thats not allowed in this page. Is there a simliar way to specify this in the web.comfig (as with code block problem) or do I have to look for another solution ?

    Appreciate all the help I can get / Andy

  • Hello. I added my server-side code to the custom Page. It's work. But How i can debug this code from VisualStudio? In which dll this code included? Also how i can work in Visaul Studio? develop my Custom page and then put it in SharePoint ?

  • Sehr wertvolle Informationen! Empfehlen!

  • I really appreciate it.It helped me a lot.
    As we will see in SharePoint 2003, it was not possible to add a simple piece of server side code in the content pages. But in SharePoint 2007 adding server side code to the content pages is possible. This can be achieved by modifying the web.config file. In the web.config file you can find tag where we need to add some lines of code.

  • This still works in 2010!! WOOO

  • You have to believe in yourself . That's the secret of success.
