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.
