Hello,

I strongly believe that this issue is on your side as I can reproduce this every single time. The steps to reproduce are these:

- Set a RadScheduleView with a TimelineViewDefinition (I think any Viewdefinition that set the ScheduleView in Horizontal Mode will have the problem).
- Set the VisibleDays of the TimelineViewDefinition to 1d.
- Set a DayStartTime and DayEndTime where the duration is higher than the DayStartTime:
ex: Start=11:00 End=16:00 so Duration=5h

I've used .Net reflector to pin point the error:

Class: TimeRulerPanel, Method: ArrangeTimeRulerGroupItem(UIElement child, Rect arrangeRect, bool isHorizontal)

Error line:

arrangeRect.set_Width((double) (tickData.Duration.Subtract(tickData.DateTime.get_TimeOfDay()).get_Ticks() / this.ScheduleView.EffectiveTicksPerPixel));

So for the example values, it's substracting the DayStartTime from the Duration (5 - 11 = -6) then converts that in pixels and setting the "arrangeRect" width to a minus pixels value which cause a ArgumentException.

Cheers!

Vonziz,

I created my own method in a class that inherits from the RadScheduleView to deal with this issue. So far I'm yet to hear of the bug being triggered in the field. Pretty much it just makes the RadScheduleView bigger to avoid the bug. I hope this helps you :)

public void SetTimeLineStartStop(TimelineViewDefinition timeline, DateTime start, DateTime stop)
{
TimeSpan dayStartTime = start - start.Date;
TimeSpan duration = stop - start;

//if duration < dayStartTime it triggers an annoying Telerik bug...
//so here we work around that issue.
if (duration < dayStartTime)
{
long ticksToAdd = (dayStartTime - duration).Ticks / 2;

start -= TimeSpan.FromTicks(ticksToAdd);
stop += TimeSpan.FromTicks(ticksToAdd);

//ReCalculate the duration
duration = stop - start;
}

this.CurrentDate = start;

timeline.DayStartTime = TimeSpan.FromHours(start.Hour);
timeline.DayEndTime = TimeSpan.FromHours(stop.Hour + 1);

timeline.VisibleDays = (int)Math.Ceiling(duration.TotalDays);
}
