Hi Dimitar,
I tried to export a RadAjaxPanel which consists of around 20 RadHtmlChart and the browser crashed (I am using IE 9). I had a look at this link http://docs.telerik.com/devtools/aspnet-ajax/controls/clientexportmanager/troubleshooting/browser-crashing for fixing similar issue but I could not generate the code. Could you please add compression scripts to your sample projects in previous post (Default.zip)?
