Erreur de grille ExtJs dans asp.net mvc

Question

J'ai toujours besoin de votre aide, et plus particulièrement de la mise en œuvre de la grille ExtJS. Je ne peux pas le faire fonctionner. J'ai une vue qui fait une recherche avec plus de paramètres, alors le contrôleur aura la recherche d'action que lors du chargement de la page je mets les contrôles de ce dernier, puis je poste l'action à travers laquelle je recherche. Voici le code:

[Authorize (Roles = "OP_Bollettino")]

03.   Search public ActionResult()

10.    Viewdata [ "abilitasur"] = abilitatosur; 
11.    Viewdata [ "checkcf"] = "false"; 
12.    abilitatocf.Add ("Disabled" "Disabled"); 
13.    Viewdata [ "abilitacf"] = abilitatocf;

     )The code to create the extjs grid is as follows:

J'ai testé un débogueur JavaScript et charger la page lorsque j'entre la grille extjs de débogage, même si je clique sur le bouton de recherche pour la recherche retour me le contenu de la requête au format bloc-notes et je n'entrerai même pas dans javascript debbugger.

Je peux vous aider à comprendre pourquoi, je l'ai essayé avec plusieurs exemples d'extjs mais ne fonctionne pas.

Merci

Answer 1

d'abord, vous devez utiliser un navigateur pour vous assurer que votre application asp.net retourner le bon format.

Lorsque vous êtes sûr à 100%, vérifiez votre code ExtJs. Type de réponse générique mais comme Thevs a souligné que vous ne devriez pas publier un tel morceau de code.

Aussi seriez-vous en mesure de poster le xml ou json votre application asp.net est de retour, il serait utile.

Answer 2

Bonjour à tous et merci pour votre réponse, je l'ai résolu le problème était que je lui ai remis les données correctes à partir d'un ExtJS JSON
