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.

Validating the HtmlPlaceholderControl


The first control that we will build is a custom validation control that works with the HtmlPlaceholderControl. Our validator will ensure that some text has been entered into the control before the page can be saved. If the author forgets to fill in content, the page will not save and an error message appears on the screen.

The figure below shows how the control works when completed. The author has left HtmlPlaceholderControl1 empty. When he or she tries to save the page, an error message, This is a required field, appears next to the placeholder, instructing him or her to fill it out before proceeding.

Retrieving the Current Value of the HtmlPlaceholderControl

In order to validate the HtmlPlaceholderControl, we need to first read off its contents. There are two ways to get its stored value—we could use server-side or client-side scripts.

We could choose to use server-side scripts and get the value stored in the Html property of the HtmlPlaceholderControl...
