Telerik RadListBox möchte nicht ziehen

Question

In meiner asp.net-Lösung versuche ich Listbox Drag-und-Drop-Funktionen zu verwenden (wie in diesem Beispiel: http://demos.telerik.com/aspnet-ajax/listbox/examples/functionality/draganddrop/defaultcs.aspx). Aber das Problem, das ich jetzt habe, ist, dass Drag and Drop nicht funktioniert. anstatt seine Markierungselemente zu ziehen ... Ich habe versucht, HTML direkt auf meine Seite zu kopieren und es funktioniert immer noch nicht. irgendwelche Ideen was kann falsch sein?

Liegt es daran, dass ich CSS vermisse?

Haben Sie versucht, Ihre Standard-Script mit einem RadScriptManager zu ersetzen?
