Thank you for writing back.
I have prepared a runnable website project from the code library. Try opening it in Visual Studio as a WebSite and try out the page.
Regarding the appearance of the picker control. Please ensure that all Telerik assembly files that are added to your project have the same version. If the Telerik.Web.UI.dll and Telerik.Web.UI.Skins.dll are different versions the Skin for the RadDatePicker could be displayed in an unexpected way.
Would you also let me know if the other suggestions (using EnableWeekends property of SpecialDays) for achieving the functionality are working for you?
I am looking forward to your reply.
