Async call in formlet
websharperasyncformletrpc

In my formlet I have the following code

1
2
3
4
5
6
7

	return! (
    	Formlet.OfElement (fun () ->
        	let resultFromServer =  Server.getfloatList inputList
            let forceList = (List.map (fun text -> LI [Text (string text)] ) (resultFromServer)) |> Seq.cast<Pagelet>
            OL [Attr.Class "jumbotron"] -< forceList
            )
         )|> Enhance.WithFormContainer

This works if the as long as I make a synchronous call. But how do the code look if I would do the same thing with a async function. Clearly the result from the server changes from float list to Async<float list>.

.

The easiest way to go is to add the elements in OnAfterRender:

1
2
3
4
5
6
7
8
9
10
11
12
13

return! (
    Formlet.OfElement (fun () ->
        OL [Attr.Class "jumbotron"]
        |>! OnAfterRender (fun ol ->
            async {
                let! resultFromServer = Server.getFloatList inputList
                resultFromServer
                |> List.map (fun text -> LI [Text (string text)])
                |> List.iter ol.Append
            }
            |> Async.Start
        )
    ) |> Enhance.WithFormContainer

Great, Thanks. And thanks for the tip of using the List.itter function as well. I am a newbie at F# so I am very thankful for all the help I can get.
