Building Websites with Microsoft Content Management Server

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. Once your website is up and running, your content contributors can add and edit content on their own, without the need to work with developers or the IT department. First time developers of Microsoft Content Management Server 2002 face a relatively steep learning curve. Not only are they expected to be conversant in the Microsoft .NET Framework, they are also required to be familiar with the concepts of MCMS 2002. Many beginners to MCMS start out by looking at the example site that ships with the product; tweaking it, dissecting it and turning it inside out using the obscure code comments as markers. However, when it comes to starting their own website from scratch, many are baffled ? where do they begin? This book exists to answer that question; teaching the essential concepts of MCMS 2002 in a clear, straightforward and practical manner. Containing answers to some of the most asked questions in developer newsgroups, this book is a treasure trove of tricks and tips for solving the problems faced by MCMS developers. This is a unique resource focused exclusively on the needs of developers using MCMS. It doesn?t waste time and pages on user or administrator level information that is well covered in other documentation. It?s a distillation of practical experience that developers need to get results, fast. The authors carefully structured example project complements and extends the knowledge gained from an initial look at the examples that ship with MCMS.

Chapter 15. Building Custom Placeholder Definitions and Placeholders

Customization does not stop at placeholder controls. You can change the way content is defined, stored, and retrieved by creating your own custom placeholder and placeholder definition classes.

We explored the placeholder definitions that ship with MCMS in Chapter 7 and saw how they are used to provide a set of rules to constrain the format of content that gets saved to the content repository. For example, the Formatting property of the HtmlPlaceholderDefinition can be set to NoFormatting to ensure that the content does not contain any block or in-line HTML tags.

Every placeholder definition has a corresponding placeholder class so, when creating your own placeholder definition, you must build a placeholder class to pair with it. A placeholder object based on this class provides a logical representation of the content and is used within code to retrieve/save data in the MCMS repository. An example of this is the standard...
