Advanced Microsoft Content Management Server Development

Overview of this book

Microsoft Content Management Server 2002 is a dynamic web publishing system with which you can build websites quickly and cost-efficiently. MCMS provides the administration, authoring, and data management functionality, and you provide the website interface, logic, and workflow. Microsoft SharePoint Portal Server (SPS) also features in the book. SPS 2003 enables enterprises to deploy an intelligent portal that seamlessly connects users, teams, and knowledge so that people can take advantage of relevant information across business processes to help them work more efficiently.You've mastered the basics of MCMS, and setup your own MCMS installation. You've only scratched the surface. This book is your gateway to squeezing every penny from your investment in MCMS and SPS, and making these two applications work together to provide an outstanding richness of content delivery and easy maintainability. As a developer, the Publishing API (PAPI) is at the heart of your work with MCMS, and this book starts by taking you on the most detailed tour of the PAPI you will find anywhere. As a live example, a component that reveals the structure of your MCMS site is created, taking you through how to manage the common elements of MCMS programmatically. Getting SharePoint and MCMS to work together is the next stop in the book. You will see how to use SharePoint's search engine to search MCMS content, publish content between the two systems, and create SharePoint Web Parts to draw content from MCMS.To ease your everyday work with MCMS, there are chapters on placeholder validation, and some useful custom placeholders for common MCMS tasks, such as a date-time picker, a placeholder for multiple attachments, and a DataGrid placeholder among others. There are a number of ways to consume MCMS content from the outside world, and we look at two exciting ways here; RSS and InfoPath/Web Services. The InfoPath solution provides another interface to MCMS content that allows content authors to concentrate on content and not the presentation. The book is rounded off with a number of must-have MCMS tips and tricks.

Implementing Server-Side Validation


We have seen how validation can be performed against the HtmlPlaceholderControl using client-side scripts. Client-side validation essentially reduces round-trips to the server just to find out if they have left out any fields. However, client-side validation does have its limitations. For instance, we can’t exactly be 100% sure that the validation did take place on the client. The user could have made a copy of the page, fired up his or her favorite HTML editing tool and modified the page to remove any form of validation. If that happens, invalid content may still find its way into the system.

In addition, not all types of validation can be done on the client. For example, you may need to match the contents of a placeholder control against an existing store of information in an online database. Or perhaps requirements dictate performing routines that can only be executed on the server.

In this example, we will extend our simple check for an empty placeholder...
