Data grid 2: disabled state for buttons that require selection

It would be really nice if buttons that require a selection from the datagrid would have a disabled state if we configure so on the datagrid. As soon as a user selects one or multiple items from the grid, the disabled state has to be removed.

Even a simple class on the datagrid when a row is selected (for example "SelectionActive") would be enough. We can then leverage CSS to add classes to buttons that require a selection and style them depending on the "SelectionActive" state. 

This will be a huge UX improvement. See image for example.
