Question

Currently I’m executing db queries this way:

_svc = new Service1Client();
_svc.GetStateCompleted += new EventHandler<GetStateCompletedEventArgs>(_svc_GetStateCompleted);

    private void _svc_GetStateCompleted(object sender, userdetCompletedEventArgs e)
    {
        //some code
    }

Calling the query function,

_svc.GetStateAsync(args);
//more code

Is there anyway I can wait after GetStateAsync till the service function returns a value?

Typically you do not wait for a long running operation to complete. There are ways to achieve that, but normally if you do not want users to interact with the application until it completes – you disable all inputs and show some sort of a progress indicator until the operation completes.
