如何将列表框绑定到位于ViewModel中的复杂类型内的集合？

Question

My view model currently contains a "SelectedClient" property which refers to the selected "Client" object in a datagrid. This selected client property contains a property titled "OfficeLocations" which is essentially just a list of "OfficeLocation" objects.

I am trying to bind a listbox to the SelectedClients.OfficeLocations property like so:

<ListBox ItemsSource="{Binding SelectedClient.OfficeLocations}" />

But for some reason the ListBox always shows up blank. Once again, in debug mode when I view the SelectedClient.OfficeLocations property, it does in fact contain data.

I've also tried something like:

<ListBox ItemsSource="{Binding SelectedClient, Path=OfficeLocations}" />

To no avail.

Any ideas would be greatly appreciated..Thanks!

Ahh, so it turns out that I was trying to do this binding with a DataGrid.RowDetailsTemplate which overrides my DataContext to SelectedItem already...meaning changing my binding to look like:

 <ListBox ItemsSource="{Binding OfficeLocations, Mode=TwoWay}">

Fixed the issue!
