Hi,
This is really a string? You get this from where? With Web Api you usually get and send objects as the underlying json serialization/deserialization is handled for you.
Once done you get an object (or a list of objets) on the client side. Binding to a grid likely depends on the kind of grid you are using (it maye have built in methods do to that or is this your own grid or a built in grid).
