    Hello.
    I Have a problem with the code shown in the Telerik RadCalendar First Look (showing in the Rad Controls Silverlight 2010 q2 Demo). I like this first demo of RadCalendar and I want to use it in one of my projects (for a school). But when I try it, i get this error message. 

    For the C# code
    1. The type or namespace name 'Event' could not be found (are you missing a using directive or an assembly reference?) .

    For the Silverlight code (xaml code), i get this error messages 
    1. The type 'local:EventsCollection' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.
    2. The type 'local:Event' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.
    3. The type 'local:EventDayTemplateSelector' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.
    4. The attachable property 'DefaultTemplate' was not found in type 'EventDayTemplateSelector'
    5. The attachable property 'EventTemplate' was not found in type 'EventDayTemplateSelector' 

    Here you can see all code of the project 

    Xaml Code:

    Hi Telarik team,

    I also have a Question in Rad Calender where I want to check a particular date I have already Colored ( Yellow) in the calender and Color again two cells after that. The question I am having is that how would you check whether the calender cells are already colored or not ,when you're iterating through the calender for the second time ( basically need to find out a get cell color method in RadCalender control - how would you know which color is there in backcolor of the day cell). I have used special days to color the calender for the first time. Please help this is an urgent work I need to finish within few days.

    Best Regards,

    Hi ranjeew,

    Let me first answer ekie's question. The error that you are getting is due to some not successfully compiled assemblies. You can download our latest Q3 2010 release and try it again. As about your question: you can explore the dates stored in the EventsCollection to check if some particular dates are presented in there.

    Best wishes,
