Hi Guys,
Panning Gestures in UltraGrid using Windows 8 and touch screen are not working, with latest Windows patches loaded.
As a sample to ensure it wasn't a problem with my Windows Form application I setup a UltraGrid, set a data source, filled it with dummy data, both horizontal and vertical scroll bars appear, gestures are enabled and touch control is added to the form but the grid does not pan when using panning gestures.
This is in WinForms 13.1
I was pretty sure this was working. It may be a Automatic Windows Update has caused an issue with the way UltraGrid does it?
Anyway, it doesn't work anymore.
The strange thing is you can't even "DRAG" the scroll bars. The only way to get the grid to scroll is actually click in the scroll bar to either side of the thumb. Touching and dragging the thumb doesn't work, doesn't move.
Works fine with a mouse though.
Any ideas?
I'm not sure if it ever worked. It may of worked initially, or appeared to, due to the intermittent, fuzzy nature of the behaviour.
With the Toshiba the DPI is set to Large Fonts, as it is a 4x Display 2560x1440. I have tried dropping the screen resolution down however and the problem persists.
On the Windows Surface Pro tablet it has the problem out of the box. Try it on a Windows Surface Pro with the test program I created and you'll see what I mean.
Hi,
Are you sure it was a windows update that triggered this behavior and not someone changing the System DPI? What is your System DPI set to currently? Can you try this with different DPI settings and let me know the results. Thanks.
Thanks !
Hello,
I have logged this issue with our developers. I have created support case CAS-121887-Z4G5P1 to track the issue. I will update this thread once the issue has been resolved or if I have other information.
It's not device specific because the issue occurs on two different devices, a Surface Pro and a Toshiba Kira.
Maybe it's due to the high res displays and small screen size, i.e. High DPI - Toshiba is 2560x1440 4xHD
The Surface is 1920x1080 but small screen so still has a high DPI
All other applications, word, excel, internet explorer work fine as you would expect. You simply perform the gesture. The scroll bar behaves the same as it does in the grid, as you would expect.
I agree the scroll bar touch and grab isn't a touch gesture. I was just explaining the action. After doing that the pan down gesture starts to work as explained, before that, the grid responds to no gestures like the application doesn't even have focus (but it does).
