<h1>TExpression</h1>
<com:DocLink ClassPath="System.Web.UI.WebControls.TExpression" />

<p>
<tt>TExpression</tt> evaluates a PHP expression and displays the evaluation result. To specify the expression to be evaluated, set the <tt>Expression</tt> property. Note, <tt>TExpression</tt> evaluates the expression during the rendering control lifecycle.
</p>

<p>
The context of the expression in a <tt>TExpression</tt> control is the control itself. That is, <tt>$this</tt> represents the control object if it is present in the expression. For example, the following template tag will display the title of the page containing the <tt>TExpression</tt> control.
</p>
<com:TTextHighlighter Language="prado" CssClass="source">
&lt;com:TExpression Expression="$this->Page->Title" /&gt;
</com:TTextHighlighter>

<p>
Be aware, since <tt>TExpression</tt> allows execution of arbitrary PHP code, in general you should not use it to evaluate expressions submitted by your application users.
