Fix RadCalendar Error

[Mmm]

Following piece of code giving me error, please see screen shot attached.

UIHelpers.SetSessionVariable("_isNewDates", false);
          if (RadCalendar1.SelectedDates != UIHelpers.CovertFromArrayList((ArrayList)UIHelpers.GetSessionVariable("_oldDates", new ArrayList())))
          {
              UIHelpers.SetSessionVariable("_isNewDates", true);
          }

          UIHelpers.SetSessionVariable("_oldDates", UIHelpers.CovertToArrayList(RadCalendar1.SelectedDates));

Check this link for exact error as I took this screenshot

I just implement RadCalendar instead of my ASP.net Calendar and hope someone can help me.

Hello,

You can use such approach:

RadCalendar1.SelectedDates.Matches(new SelectedDateCollection( YourListHere ))
