I am trying to disable the calendar icon used in the RadDatePicker. I used "EnableEmbeddedSkins="False" but all this did was give me a broken image icon. Is there another way or is this even possible?

Hello Eric,

When you disable the embedded skin for RadDatePicker for ASP.NET AJAX, you need to register manually the skins/images used by the control in order to display them as expected. Review the following online help articles for more details:

http://www.telerik.com/help/aspnet-ajax/disabling_embedded_resources.html
http://www.telerik.com/help/aspnet-ajax/calendar_appearanceskins.html (paragraph customizing skins)

In case you merely want to disable or hide the popup button, set the DatePopupButton  -> Visible/Enabled property of the date picker to False or replace the picker with RadDateInput instead.

Kind regards,
Stephen
