n my previous article I have discussed about basic architecture of WPF, and then gradually started learning with Layout panels, Transformation, introduced different Controls, containers, UI Transformation etc. In this article I will discuss the most important part of XAML which every developer must learn before starting with any XAML applications.
Markup Extensions are extensions to XAML which you might use to assign custom rules on your XAML based Applications. Thus any custom behavior which you would like to impose on your application in your designer, you should always use Markup Extensions. Here we will discuss how you can use Markup Extensions to generate your custom behaviors to XAML.
XAML or Extensible Application Markup Language is actually an XML format which has special schema defined. Now you might always wonder, how extensible the Markup is. What type of capabilities that are there within XAML which widely differs the XAML with XML. Yes, it is because of XAML parser which has huge number of capabilities to make the normal XML to a very rich UI designs.
You all know XAML is actually a text format. The tags are very same as with any XML where the attributes takes everything as String. Even though you want to assign a object to a string, you cannot do so because the object can only take a string. Markup Extension allows you to handle these kind of situations. So you can say a Markup extension is actually the way to extend a normal XML to a complete Extensible Markup as XAML.
