Gesturing, stylus doesn't work but touch with finger does.

[Will]

Hi,
We have a problem with gesturing.
We found out that gesturing with the stylus doesn't work properly.
Let us take radcombobox as example. 
Please use the stylus (real stylus which you use on for example Microsoft surface, not this rubbery one)  and the finger only for a test. When you use stylus on radcombobox the list of items drops down but if you selecting item it highlights it but that is it. The highlighted value is not going to the selected text area and the list of items is not collapsing. When you use the finger touch or cursor and mouse it all works. It is just stylus. We have to have stylus to work. The same issue is with other components like for example raddatetimepicker. 
Please help us with this problem.

Thanks,
Grazyna Weimann

Hi Grazyna,

It seems strange that it does not work only when stylus is used, but sadly at this moment we can't get our hands on device with active stylus in order to test this behavior.
Meanwhile until we find such device it would be great if you could provide us more information, like:

• Can you confirm that it happens only when you touch something in drop down (popup). For example it works on buttons and GridView row, but it does not work on items in the ComboBox or on the Calendar of the DateTimePicker?
• Can the issue be reproduced with any of the borders from the attached project? You can observe if the TouchDown and TouchUp events are fired in the TextBox on the right. If there is some difference there between finger and stylus, sending us the text of the TextBox would also help.
• Does handling of the events in the attached project has any effect when the stylus is used?
• Does setting TouchManager.IsTouchEnabled = false;  before InitializeComponent() helps with the ComboBox selection?

I have also attached an image showing how the events are raised on my machine using finger on touch monitor.

Looking forward to your reply.

Yes it is strange but it does not work consistently. Answering your questions:
1. Yes it seams it happens only in something popup. But some popups works some don't. Example raddatetimepicker it works on time pickup but it doesn't on date pickup.
2. It seams that I cannot reproduce issue in your sample.
3. The events are fired.
4. TouchManager.IsTouchEnabled = false;  before InitializeComponent() helps only with combobox but not with raddatepicker. If I have this property for true even touch with the finger does not work on raddatepicker.
5. I also mentioned in the grid when you open the filter main check box select all also does not respond to stylus.
The issue is very important since our client is complaining that in previous version it was working when we updated to new version of telerik it stopped working. So maybe please compare this with older version of telerik. Our client works only on tablets using stylus and finger touch mostly sometime they use mouse pad.
Appreciate any help.

Files. This is with the ouchManager.IsTouchEnabled = false;  before InitializeComponent(). The finger touch is exactly like stylus. Works on time doesn't on date.
With ouchManager.IsTouchEnabled = true;  before InitializeComponent() stylus stil doesnt work but touch with finger does.

This png file is actually mov so it is short clip. Please rename to .mov after downloading. You will see how it works with the stylus.

Hello Grazyna,

Thank you for the detailed information and the provided video.

We were able to test the issue on a tablet with stylus and we were able to reproduce it. Therefore we have logged it here in our feedback portal where you can track its progress.

Unfortunately so far we were not able to find any workaround for the issue.

Please, excuse us for the inconvenience caused and if you have any other questions or concerns, please don't hesitate to write us.
