Touch devices may need to tap twice on a button to fire command.
This always happens on my end when the button is located alongside a textbox or other elements on a user or windows control.
The fix.
1. Add a touch down event for the event in the xaml.
2. Fire command manually
MapEntity commandParameter = (MapEntity)(((Button)sender).CommandParameter);
var viewModel = (FindADISViewModel)DataContext;
if (viewModel.OpenDIS.CanExecute(commandParameter))
viewModel.OpenDIS.Execute(commandParameter);It works!
