<p id="610410" class="block-content"><tt>TActiveButton</tt> is the active control counter part to
<a href="?page=Controls.Button">TButton</a>.
When a <tt>TActiveButton</tt> is clicked, rather than a normal post back request a
callback request is initiated. The <tt>OnCallback</tt> event is raised
during a callback request and it is raise <strong>after</strong>
the <tt>OnClick</tt> event.
</p>
<p id="610411" class="block-content">When the <tt>ActiveControl.EnableUpdate</tt> property is true,
changing the <tt>Text</tt> property during a callback request will update
the button's caption on the client-side.</p>
<p id="610412" class="block-content">Since the <tt>OnCallback</tt> event is raised only during a callback request,
the <tt>OnCallback</tt> event handler can be used to handle logic specifically
related to callback requests. The <tt>OnClick</tt> event handler is raised
when ever the button is clicked, even if javascript is disabled.</p>
<p id="610413" class="block-content">The following example the use of both the <tt>OnClick</tt> and <tt>OnCallback</tt>
events of an <tt>TActiveButton</tt>.</p>
