You can set the <tt>CallbackParameter</tt> property from javascript directly on the object returned by <tt>ActiveControl.Javascript</tt>. Once you are ready, you can call the <tt>dispatch()<tt> method on the object to execute the callback. The server-side event <tt>OnCallback</tt> is raised when a callback is requested made. </p> <p class="block-content"> Example usage: </p> <com:TTextHighlighter Language="text" CssClass="source block-content" > <com:TCallback ID="callback1" OnCallback="callback1_Requested" /> <script type="text/javascript"> function do_callback1() { var request = <%= $this->callback1->ActiveControl->Javascript %>; request.dispatch(); } </script> <div onclick="do_callback1()">Click Me!</div> </com:TTextHighlighter> <com:RunBar PagePath="ActiveControls.Samples.TCallback.Home" /> </com:TContent>
