A component property can be viewed as a public variable describing a specific aspect of the component, such as the background color, the font size, etc. A property is defined by the existence of a getter and/or a setter method in the component class.

A namespace in PRADO is considered as a directory containing one or several class files. A class may be specified without ambiguity using such a namespace followed by the class name. Each namespace in PRADO is specified in the following format,

<p>
Dynamic component instantiation means creating component instances in PHP code. It is the same as the commonly referred object creation in PHP. A component can be dynamically created using one of the following two methods in PHP,
-<pre class="source">
+<com:TTextHighlighter CssClass="source">
$component = new ComponentClassName;
$component = Prado::createComponent('ComponentType');
-</pre>
+</com:TTextHighlighter>
where <tt>ComponentType</tt> refers to a class name or a type name in namespace format (e.g. <tt>System.Web.UI.TControl</tt>). The second approach is introduced to compensate for the lack of namespace support in PHP.
</p>
<h3>Static Component Instantiation</h3>
<p>
Static component instantiation is about creating components via <a href="?page=Configurations.Overview">configurations</a>. The actual creation work is done by the PRADO framework. For example, in an <a href="?page=Configurations.AppConfig">application configuration</a>, one can configure a module to be loaded when the application runs. The module is thus a static component created by the framework. Static component instantiation is more commonly used in <a href="?page=Configurations.Templates1">templates</a>. Every component tag in a template specifies a component that will be automatically created by the framework when the template is loaded. For example, in a page template, the following tag will lead to the creation of a <tt>TButton</tt> component on the page,
