Dynamic content tags are introduced as shortcuts to some commonly used <a href="?page=Configurations.Templates1#ct">component tags</a>.

An expression tag represents a PHP expression that is evaluated when the template control is in <tt>PreRender</tt> stage. The expression evaluation result is inserted at the place where the tag resides in the template. The context (namely <tt>$this</tt>) of the expression is the control owning the template.

Statement tags are similar to expression tags, except that statement tags contain PHP statements rather than expressions. The output of the PHP statements (using for example <tt>echo</tt> or <tt>print</tt> in PHP) are displayed at the place where the statement tag resides in the template.

Databind tags are similar to expression tags, except that the expressions are evaluated only when a <tt>dataBind()</tt> call is invoked on the controls representing the databind tags.

Asset tags are used to publish private files and display the corresponding the URLs. For example, if you have an image file that is not Web-accessible and you want to make it visible to end-users, you can use asset tags to publish this file and show the URL to end-users so that they can fetch the published image.

where <tt>LocalFileName</tt> refers to a file path that is relative to the directory containing the current template file. The file path can be a single file or a directory. If the latter, the content in the whole directory will be made accessible by end-users.

BE VERY CAUTIOUS when you are using asset tags as it may expose to end-users files that you probably do not want them to see.
