Hello,

You can take advantage of RadListView.Commands collection and define a ListViewUserCommand with ItemTap id and bind its Command property to an ICommand from your model.

I hope this helps.

Hello,

you don't understand me. I have in xaml this:

<telerikDataControls:RadListView.Commands>
<telerikListViewCommands:ListViewUserCommand Id="ItemTap" Command="{Binding Expenses.EditVehicleExpenseCommand}" EnableDefaultCommand="False"/>
</telerikDataControls:RadListView.Commands>

But in this way command does not have DataContext from ListView. I cannot define context as static source, while I assign viewmodel in event OnNavigatedTo, it's dynamic and not static. So I don't known, how should I defined it.

Best Regards
