How do I set minimum size of scrolling region?
Hm... This is good tip, thanks. I try BeforeRowRegionSize and BeforeColRegionSize handlers.
What kind of Scrolling region? RowScrollRegion or ColScrollRegion?
I don't see any MinimumSize property, but there is a SizingMode which you can set to Fixed. So you can fix the region at a particular size.
You could also handle the BeforeRowRegionSize (or BeforeColRegionSize) event and cancel it.
