Question : DataGrid(QuickGrid) How can I update on client side. about bolero HOT 1 OPEN

What happens here is that the message is dispatched; but the dispatch function just queues the message to be processed. It doesn't wait for it (or the Cmds it caused) to be completed. So when you look at the model right after calling it, nothing has changed yet.

I think a good way of doing this would be to pass a callback in GetBooks, that would be called at the end of processing it in the update function.

So you would declare your message type like this:

type Message =
    | GetBooks of sql: string * onCompletion: (IDictionary<string, string> -> unit)

then replace your steps 2 and 3 with:

let! dic = Async.FromContinuations (fun (onCompletion, _, _) ->
    dispatch (GetBooks (sql, onCompletion)))

and finally, in the update function, at the end of processing GetBooks, call onCompletion with the retrieved books.

Additionally, this gets rid of all the mutation you have, both with the local dic value, and in your model.
