Message d'erreur, « La collection Controls ne peut pas être modifié car le contrôle contient des blocs de code »

Question

Je reçois cette erreur sur une page qui fonctionnait très bien, en fait, le seul changement que je l'ai fait récemment à la page a été d'ajouter un autre asp: TextBox et asp:. Contrôle RequiredFieldValidator

La page avait déjà de nombreux contrôles ASP.NET sur, donc je ne vois pas pourquoi ces contrôles supplémentaires feraient une différence, de toute façon je posterai le code ci-dessous et nous espérons que vous pouvez voir ce que l'erreur est:

Answer 1

Il a été trié en supprimant les blocs de code des sélecteurs de jQuery et de les changer pour nom * = sélecteurs à la place. Changement de <% = à <% # n'a pas résolu le problème, nous espérons que le changement de sélection fonctionne pour les autres.

Answer 2

Essayez de changer <% = à <% # au sein de votre script jQuery. Consultez cette article
