ScrollViewerEx does not work with touch screens

Hey, would you have a device with a touchscreen to check if you can still slide through scrollviewer and other components using Inkore Modern WPF ?
Looks like it no longer works for me.
I'm wondering if that's a scrollviewer issue actually.

Can you be more specific? In touch screens it seems that the scroll bar will no longer work, instead you need to swipe the whole view instead of dragging the bar

That's` the opposite. I can no longer swipe the view and have to touch the scrollbars.

Are you using ScrollViewer or ui:ScrollViewerEx?

Pretty sure I tried both.
I might have to look through my app releases to the point where touch works and stopped working.

Hmph, are there any scrollable controls, including lists and sliders inside your outer ScrollViewer?

Sliders, comboboxs

ComboBoxes should work with no issues

There have been an existing issue that a slider may prevent the outer scroll viewer from scrolling with touch. But it think that's something related to WPF touch events.

You should do something like e.Cancel (I forgot) to keep the touch events bubbling

Is that a new issue ? Because it was working fine a few months ago so something has changed somewhere in the meantime.
Either in Modern Wpf or on my end.

I'm not sure, because his report was a little bit different

(A few days later...)

Fixed my issue...

Oh blimey, does that mean this is a mistake made by .NET team?

I think it's a very old bug from .NET indeed.

Welll, we tried. the only thin to do is to hope the .NET team would fix it someday.
