MVVM multiple bindings on a User Control

Question

I have a UserControl "SubjectListView". The binding is set to "AllSubjects" which is an ObservableCollection inside the SubjectListViewModel. It is used to retrieve the name and execute the command. The name is retrieved, however the command which is also in the SubjectListViewModel is not executed on the button but works on the button which is not dynamically created outside the scope.

Is there a solution?

<StackPanel> <ItemsControl ItemsSource="{Binding AllSubjects}"> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <Button Width="100" Content="{Binding Name}" <!-- Is working--> Command="{Binding InvasionCommand}" <!--Is NOT working--> /> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> <Button Content="Check for Invasion" Width="120" Command="{Binding InvasionCommand}" <!-- Is working-->/> </StackPanel>

give your outermost StackPanel an x:Name. on your Command Binding, use ElementName to direct to the named StackPanel, then do Path=DataContext.InvasionCommand — Jake Berger

The problem is, that InvasionCommand is in your viewmodel (i think so), but you're in the actual element of your ItemsSource..

For that, I use ElementSpy, but I think it will work if you use a RelativeSource..

Here you have an overview of all possible Bindings: http://www.nbdtech.com/Free/WpfBinding.pdf

Or, if you give your StackPanel the name Container, you could bind following:

Binding ElementName=Container, Path=DataContext

Thanks I set the StackPanel and set the ElementName and it is working now.
