does knows how that?

i thinking ajax thing it's typed view , datas associated model.

not sure if solution if put listbox partial view (strongly typed well), , ajouterfonction() javascript make ajax call action returns partialview containing updated version of listbox? use jquery replace previous listbox new one.

controller action:

public partialviewresult actionname(<whatever need here>) {     // whatever logic may need: item clicked, should added model object, etc....     return partialview("listboxpartial", yourmodelobject); }

partial view listboxpartial:

@model yourmodel @html.listboxfor(contact => contact.selectedfonctionids, model.listefonctionsselectlist, new {disabled = "disabled" })

in view, instead of 

<div class="span9">                                             @html.listboxfor(contact => contact.selectedfonctionids, model.listefonctionsselectlist, new { disabled = "disabled" })                                 </div>

you'd have:

<div class="span9">                                            @html.partial("listboxpartial", model)                         </div>

your ajouterfonction(), after receiving new listbox, ajouterfonction() searches div class "span9" , replaces contents received data.

there may better way of solving this, first thing popped mind.
