 Collection is a basic data structure in programming. In traditional PHP programming, array is used widely to represent collection data structure. A PHP array is a mix of cardinal-indexed array and hash table.

 To enable object-oriented manipulation of collections, PRADO provides a set of powerful collection classes. Among them, the <tt>TList</tt> and <tt>TMap</tt> are the most fundamental and usually serve as the base classes for other collection classes. Since many PRADO components have properties that are of collection type, it is very important for developers to master the usage of PRADO collection classes.

 <h3 id="5504">Using <tt>TList</tt>-based component properties</h3>

 As aforementioned, many PRADO component properties are based on <tt>TList</tt> or <tt>TList</tt>-derived collection classes. These properties all share the above usages.

 For example, <tt>TControl</tt> (the base class for all PRADO controls) has a property called <tt>Controls</tt> which represents the collection of child controls. The type of <tt>Controls</tt> is <tt>TControlCollection</tt> which extends <tt>TList</tt>. Therefore, to append a new child control, we can use the following,

 Often, we want to extend <tt>TList</tt> to perform additional operations for each addition or removal of an item.

 <h3 id="5506">Using of <tt>TAttributeCollection</tt></h3>

 <tt>TAttributeCollection</tt> is a special class extending from <tt>TMap</tt>. It is mainly used by the <tt>Attributes</tt> property of <tt>TControl</tt>.
