We have noticed some strange behavior when drilling down to a day view whilst in a week view.  The delegate attached to the VisibleRangeChangedCommand sometimes fires twice.  We connect the command up in the ScheduleView XAML as follows:

VisibleRangeChangedCommand="{Binding VisibleRangeChanged}"
VisibleRangeChangedCommandParameter="{Binding VisibleRange, RelativeSource={RelativeSource Self}}"    

The delegate is attached to the command in the view model constructor:

this.VisibleRangeChanged = new DelegateCommand(this.VisibleRangeExecuted, (param) => true);

The problem doesn't exist when drilling into day view from a month view definition.  It only happens intermittently when drilling down into a day view from a week view definition.

Looks like a bug to me.

Is there a known work around until the bug is fixed?  We have logic that randomly gets executed twice due to this.

I've found a fairly crude hack:

        private void radScheduleMovements_VisibleRangeChanged(object sender, EventArgs e)
        {
            var range = (sender as RadScheduleView).VisibleRange;
            var dateSlot = (sender as RadScheduleView).MouseOverSlot;


            //Prevent first event firing when clicking on day slot header in month view (where the date header is in a
            //different month e.g Display is for month of September.  Click on day header for 31st August.  Event fires
            //twice.  One for change of month and one for change of day.  Known issue with Telerik ScheduleView control.)
            if (dateSlot != null)
            {
                if (range.End != dateSlot.End && range.Start != dateSlot.Start) return;
            }


            ViewModel.VisibleRangeExecuted(range);
        }
