Question

I have two datagrids in a single view but the collections which are ItemsSource of these datagrids are in different View Models. So is it possible to bind these two datagrids with the collections in two different View Models?

Answer 1

Go for a view model combining both:

public class ViewModelA {
    public ObservableCollection<CustomClass> Items { get; set; }
    /* properties, etc. */
}

public class ViewModelB {
    /* properties, etc. */
}

public class CombiningViewModel {
    public ViewModelA A { get; set; }
    public ViewModelB B { get; set; }
}

Binding can be done like

<DataGrid ItemsSource="{Binding A.Items}">
    <!-- Sample, not complete -->
</DataGrid>
