TimelineBand vertical clip

Feb 3, 2014 at 9:00 PM
Hi there
Is there any chance to catch the moment of TimelineBand vertical clipping?
My user wants to change the vertical size of container in which the Timeline control resides. When shrinked vertically, the TimelineBand main band hides its events with no traces.
My idea is to count hidden items and show a warning/label to let user know that she has more.
Any clue?
Thanks.
