Fehlermeldung: „Die Controls-Auflistung kann nicht geändert werden, da die Steuercodeblöcke enthält“

Question

Ich erhalte diesen Fehler auf einer Seite, die vorher gut funktioniert, in der Tat die einzige ich auf die Seite habe vorgenommene Änderung wurde vor kurzem eine weitere asp hinzufügen: TextBox und asp:. RequiredFieldValidator Kontrolle

Die Seite bereits zahlreichen ASP.NET-Steuerelemente auf sie hatte, so kann ich nicht sehen, warum diese zusätzlichen Kontrollen einen Unterschied machen würden, jedenfalls werde ich nach dem Code unten und hoffentlich können Sie sehen, was der Fehler ist:

Answer 1

Es wurde durch Entfernen der Codeblöcke aus dem jQuery Selektoren sortiert und ändern sie * = Wähler statt zu nennen. Ändern <% = auf <% # hat das Problem nicht lösen, hoffentlich wird die Auswahländerung für andere Menschen arbeiten.

Answer 2

Versuchen Sie, <% = auf <% # in Ihrem jQuery-Skript. Schauen Sie sich diese Artikel
