I don't see the issue the way you point it. Unfortunately we'd need more information. The arrow showing feature is still in recent versions of Ext.NET and they are displayed when it is required, by what I could reproduce here.
But, there's an issue where the lower arrow
is off screen. That's just the 'down arrow' that is getting off-screen. Scrolling still works if we use the mouse wheel. And for this issue, we created the issue #1607
But the noticed issue does not really look like the screenshots you shared.
If your issue really misses not just one, but both, and also the menu is not scrollable at all, then please provide us a test case to reproduce it. If in doubt, please refer to our threads about more information to fulfill a support request:
- Tips for creating simplified code samples
- More Information Required
- Forum Guidelines
We will be unable to further discuss issues with -both- scroller buttons in the menu, or total scrollability, unless a sample to reproduce the issue is provided.
Regardless of that, we'll post an update here when we have the acknowledged issue above fixed on Ext.NET (either by our own, or fixed upstream by Sencha).
