Hello guys,
The multisorting in RadGridView on desktop works very well with the help of "Shift" key.
But I want to implement it for the tablet computer. I want to be able to do a multisorting on my RadGridView by tapping and holding (https://docs.telerik.com/devtools/wpf/common-information/touch-support) a column instead of the "Shift" key.
How can I do this?
Thanks in advance for your help.

Not sure if this belong here or in the RadListBox-forum. But anyway...
I've got a RadListBox bound to an ObservableCollection with 2000 items. The items are displayed using a DataTemplate with an Image and a TextBlock. I've also implemented filtering of the items using a regular TextBox together with an IsVisible-property on the items. When entering text in the TextBox I hide all the items not matching the searchstring. Filtering works great, but I've noticed severe performance hits when running this on laptops with touch-screens (Windows 10). It works reasonably well when hiding items, but when clearing my filter (i.e. setting a lot of items to be visible again) it's really slow. I have set the TouchManager.IsTouchEnabled to false, and the AutomationManager.AutomationMode is disabled. It doesn't matter if i turn on or off the VirtualizingPanel.IsVirtualizing on the RadListBox. The only thing that I've found to work is by opening the device manager and disable the touchscreen-HID device, so I'm fairly certain that the performance hit is due to the touch-functionality.

Hello,
is it possible to test an application that uses the Touchmanager events on a machine that has no touchscreen? My main development machine has no touchscreen and it is a little cumbersome to deploy the application for each test on the target device.
Is there a way to simulate at least the Tap-event with a mouse click?
Beste regards,
Thomas
