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.

Chapter 9. Validating Placeholder Controls

Before content is saved, it is often necessary to validate it to ensure some level of data integrity. It’s often necessary to look for empty fields, check for invalid date formats, or even compare values between two or more controls.

Typically web forms can’t be submitted until such validation checks have been passed. For example, when an author attempts to submit a form without filling in a mandatory field, a friendly error message appears on the screen. He or she will have to enter content into the field before the form can be submitted successfully.

Such validation techniques are common in regular web applications. However, for MCMS websites, validation, if done at all, is often secondary. Part of the reason lies in the fact that ASP.NET validation controls, which work great with controls in regular web forms, do not work with MCMS placeholder controls.

To get around this problem, we need to build our own controls...
