    PROJECT DESCRIPTION
    The attached code demonstrates how to create a MVVM app with a RadGridView with right click Context Menu functionality as well as the ability to double click a row and have it fire a command in the ViewModel.

    A full write up of this using Prism as well as MVVM will be listed at http://www.compositedevpatterns.com Go to the Training (Prism) category, Lesson 9.

    In short, there is an assembly named WPFMVVMPrism which is based of the Cinch Framework but also includes some other code.

    This demonstrates how you can right click on a row and display a Contextmenu and select a menuItem and have it pass the CurrentItem back to the ViewModel.

    Also, it allows you to double click a row and have the row Item passed back to your viewModel.

    Updated the sample to use the PreviewMouseRightClickDown event.  Also, I was advised that the IsSelected command will be deprecated so fixed the code in this version.

    I'm having a little trouble with the double-click functionality.  I'd like to limit it to when the user just double-clicks a row and not anywhere in the grid, like you have here.  As an example, click to select a row, and then try double-clicking on a column header.

    Edit:
    Nevermind. I found this in another one of your posts:

    private void RGV_PreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
    {
        e.Handled = ((FrameworkElement)e.OriginalSource).ParentOfType<GridViewRow>() == null;
    }
