I have legend like this below - but issue is main root element 'Group Layer' is not being checked in legend control of the application. But this is checked in map document.

I would need more infos about:
- what kind of layer is your 'Group Layer' (is it a Group Layer Collection or a sub group layer inside a DynamicMapServiceLayer?)
- the meaning of 'is not being checked in legend control' : by default there is no checkbox in the legend. You can customize it to add checkboxes but in this case I need to know how you binded that checkbox.

If for example you binded your checkbox to LayerItemViewModel.IsEnabled and if your layer is a group layer collection, the checkbox represents the group layer visibility so you should not be able to have a group layer visible in the map and not checked in the legend.
