Dynamic property tags are very similar to dynamic content tags, except that they are applied to component properties. The purpose of dynamic property tags is to allow more versatile component property configuration. Note, you are not required to use dynamic property tags because what can be done using dynamic property tags can also be done in PHP code. However, using dynamic property tags bring you much more convenience at accomplishing the same tasks. The basic usage of dynamic property tags is as follows,

<h3>Databind Tags</h3>
<p>
-Databind tags are similar to expression tags, except that they can only be used with control properties and the expressions are evaluated only when a <tt>dataBind()</tt> call is invoked on the controls represented by the component tags. In the expression, <tt>$this</tt> refers to the control itself. Databind tags do not apply to all components. They can only be used for controls.

<h3>Asset Tags</h3>
