MainWindow:

Answer 1

Assuming that your MainWindows Datacontext is an instance of MainWindowViewModel, you can bind the usercontrol to TvshowGridViewModel like this:

<Window>
... 
<Grid x:Name="LayoutRoot">
    <views:TvshowGridView DataContext={Binding TvshowGridViewModel} x:Name="TheTvshowGridView" Margin="8,8,8,58.96" Grid.Row="1"/>
</Grid>

You also should change the TvshowGridViewModel property code like shown:

public TvshowGridViewModel TvshowGridViewModel 
{ get{return _tvshowGridViewModel;} }
