Hello,
I'm having problems getting RadDatePicker to work. It does not show the calendar when I click on the Icon, and the page throws errors when it reloads.
I'm setting the RadDatePicker with code. Here are snippets of my code and some error screenshots:

There are some steps you may take in order to resolve the issue:
1. Remove RadCompression from your web.config in case it is enabled:
http://www.telerik.com/help/aspnet-ajax/compression.html
2. If you have more code in your real project, make sure that you are not using RadAjaxPanel or RadAjaxManager at the same time. They should not be implemented simultaneously:
http://www.telerik.com/help/aspnet-ajax/ajax-controls-in-ajaxpanel-and-ajaxsettings.html
3. If the issue remains, temporarily remove any ajaxification (RadAjaxManager) on the page and enable your script debugger (FireBug or F12) to see whether a more descriptive script or server error will arise. And if it does, you can debug the problematic lines of the application to track down the issue and root it out.
Hope this helps.
