  • How to register DefaultWebPartRegistration?

    • Hello, Tobias.
      How do I register the DefaultWebPartRegistration? I tried it with the ff. in my pagelayout:
      <%@ Register Tagprefix="wp" Namespace="SPProject.Controls"%>
      But after creating the page I get the ff. error:
      Unknown server tag 'wp:DefaultWebPartRegistration'.
    • Hi Gary,
      I assume that the DefaultWebPartRegistration class is added to the SPProject.Controls namespace. In this case, you both need to add a SafeControl entry for the namespace and add the @Assembly instruction on the page.
      You can add the SafeControls entries using the Visual Studio GUI. For a guide, look at this post:
      To add the assembly preprocessor, you can use the dynamic declaration of the SharePoint project using this syntax:
      <%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>
      This will add the assembly name according to your setup.
      Hope this helps!
  • The code works only when page is edited

    • Hi Tobias,
      This is a great post.  The only thing i would like to ask is.  The default web parts gets added to a page only when the page is edited.  They dont appear on the page immed. after creating the page using a page layout.  please could you help.
    • Hi, what account is creating the page?
      The functionality is not meant for programmatic creation or for use with site definitions - in that case I provision the web parts using a module in the site def.
      Have you got any further information or steps that can guide me in helping you?
