CPradoViewRenderer implements a view renderer that allows users to use a template syntax similar to PRADO templates.
To use CPradoViewRenderer, configure it as an application component named "viewRenderer" in the application configuration:
CPradoViewRenderer allows you to write view files with the following syntax:

CPradoViewRenderer allows you to write view files with the following syntax:
// PHP tags:
<%= expression %>
// <?php echo expression ?>
<% statement %>
// <?php statement ?></li>
// component tags:
<com:WigetClass name1="value1" name2='value2' name3={value3} >
// <?php $this->beginWidget('WigetClass',
// array('name1'=>"value1", 'name2'=>'value2', 'name3'=>value3)); ?>

// clip tags:
<clip:clipID >
