</form>

d'apres ce que j'ai compris, le champ __VIEWSTATE conserve l'etat des differents controles du formulaire et les valeurs des champs __EVENTTARGET et __EVENTARGUMENT sont modifies dans la fonction javascript suivante avant que le submit ne survienne :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}

Voici donc ma petite fonction de post d'un formulaire.

url = la valeur post du formulaire en question
formValues = les valeurs des differents input de type hidden sous la forme d'un dictionnaire.
