In am having issue with ImageEditor whereby the custom dialog control trigger Ajax request event every time the toolbar is clicked. I couldn't find any reason for it to trigger the event. Any idea?

ASPX:
01.  <script type="text/javascript">
02.        function add_div_event() {
03.            $("body").on('click', '.frameImage', function (e) { selectFrame(this) });
04.        }
05.    </script>
06. 
07.</head>
08.<body onload="add_div_event()">
09.    <form id="form1" runat="server">
10.        <telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>
11.        <telerik:RadAjaxManager ID="ajaxManager" runat="server" OnAjaxRequest="ajaxManager_AjaxRequest" >
12.            <AjaxSettings>
13.                <telerik:AjaxSetting AjaxControlID="ajaxManager">
14.                    <UpdatedControls>
15.                        <telerik:AjaxUpdatedControl ControlID="imgEditor"  />
16.                    </UpdatedControls>
17.                </telerik:AjaxSetting>
18.            </AjaxSettings>
19.        </telerik:RadAjaxManager>
20.        <div id="main">

63.            </div>
64.            <telerik:RadScriptBlock ID="scriptBlock" runat="server">
65.                <script type="text/javascript">
66.                    Telerik.Web.UI.ImageEditor.CommandList["CustomInsertImage"] = function (imgEditor, commandName, args) {
67.                        imgEditor.executeCommand("CustomInsertImage");
68.                        };
69.                        Telerik.Web.UI.ImageEditor.CommandList["SaveFrame"] = function (imgEditor, commandName, args) {
70.                            imgEditor.saveImageOnServer("", true);
71.                        };
72. 
73.                        function OnClientImageLoad(sender, args) {
74.                            var editorWidth = sender.get_width().substring(0, sender.get_width().lastIndexOf("px"));
75.                            var editorHeight = sender.get_height().substring(0, sender.get_height().lastIndexOf("px"));
76.                            sender.zoomImage(43, true);
77.                        }
78. 
79.                        function selectFrame(obj) {
80.                            //alert('frameselected');
81.                            var img = obj.childNodes[1];
82.                            //alert(img.src);
83.                            var ajaxManager = $find("<%= ajaxManager.ClientID %>");
84.                            ajaxManager.ajaxRequest(img.src);
85.                        }
86.                </script>
87.            </telerik:RadScriptBlock>
88.        </div>
89.    </form>

Somehow this command
Telerik.Web.UI.ImageEditor.CommandList["CustomInsertImage"] = function (imgEditor, commandName, args) {
67.                        imgEditor.executeCommand("CustomInsertImage");
68.                        };

always trigger OnAjaxRequest and causing the image editor to loose the image.

Problem solved by setting ajaxManager.set_enableAJAX(false); when ajax is not required.
