Dear Customer,

 Try this way

 1. Add the code below into the custom dialog page. My test dialog page under folder “\CuteSoft_Client\CuteEditor\Dialogs\”. So just make the url correct which point to file “Load.ashx”.

 <script type="text/javascript" src="Load.ashx?type=dialogscript&verfix=1004&file=DialogHead.js"></script>

 2. Use code do_Close() to close the dialog, like below.

 <input class="formbutton" type="button" value="[[Cancel]]" onclick="do_Close()" />

 Keep me posted.

 Regards,

Ken
