We have implemented the HeaderVisibility
for cases like this. If you use the calendar as:
<telerikInput:RadCalendar Width="300" Height="200" HeaderVisibility="Collapsed"/>
It will have no header and no navigation controls.
If you want to remove just the arrows than you will have to edit the calendar template. The problem is that than the user will be able to click the title and go from month view to year view or decade view. I have attached an example with modified template. You can use the template to modify one of our themes or edit the calendar yourself. It's quite easy in blend. The modified lines are in the MainPage.xaml near the:
<!-- Header buttons and title.. set the visibility / enabled to format them properly -->
Thanks for your interest in our controls.
