I'm using the 2011 Q3 release for Silverlight... I'm trying to limit the minimum range to 7 days. I've tried setting the MinSelectionRange in the XAML and in the code-behind but it doesn't seem to stick. I can still select a single day. I used a previous version of the control in another project and this functionality worked fine. I was only able to select blocks of 7 days or more. Anyone know what's going on with this now?
