Cross-page Web Part Connections

Some interfaces can be used to connect a Web Part on one page (the source page) to a Web Part on a different page (the target page). The behavior is similar to a hyperlink.

You should keep the following about cross-page connections in mind:

  • A Web page editor that is compatible with Microsoft® Windows® SharePoint™ Services, such as Microsoft Office FrontPage® 2003 is required to author cross-page connections. However, once a cross-page connection has been formed, it can be used by any supported Web browser at run time.
  • Only connectable Web Parts that have implementations designed to run on the server (CanRunAt = ConnectionRunAt.Server or CanRunAt = ConnectionRunAt.ServerAndClient ) can establish cross-page connections. Connections that are formed on the client side are not allowed to cross Web Pages.

The following table shows the interfaces that can be connected across pages.
