If there is only one audio device connected to Windows 10, computer will detect and configure the device so that you can play audios through it by default after connection. Common audio output devices include headphones, speakers, sound cards, etc. This post from MiniTool teaches people how to play sound on two or more audio output devices simultaneously.Īn audio output refers to the device which can play sound and drive signals into another device's audio input. Luckily, Windows allows them to choose which sound output to use when there are multiple audio outputs detected on Windows 10.
Public ’s a common situation that users have more than one audio output device connected to the computer. SelectedModels = new ObservableCollection() View Model: public class ModelListViewModel This workaround make use of interactivity event trigger and interactions set property mechanism in above assemblies.Īdditional namespace declaration in XAML xmlns:i="clr-namespace: assembly="
If you need these, it can be download from here If you are using and already, here is a workaround without any other code/behaviour to mess around. Hope it prevents someone spending the huge amount of time I did to figure out how to receive SelectedItems as CanExecute parameter. Private bool OnDeleteSelectedItemsExecute(object SelectedItems)įor example, you can either send a listview/listbox's SelectedItems property to you ICommand methods or the listview/listbox it self. private bool OnDeleteSelectedItemsCanExecute(object SelectedItems) This way you can prevent silenced cast exceptions that occurs whenever databinding CommandParameter type does not match your command method's parameter type. Make sure your ICommand's CanExecute and Execute methods have a parameter of object type. To make it work you must follow ALL the following rules:įollowing Ed Ball's suggestion', on you XAML command databinding, define CommandParameter property BEFORE Command property. Like Doctor has already pointed out, you can bind SelectedItems to XAML CommandParameterĪfter a lot of digging and googling, I have finally found a simple solution to this common issue.
