c# - Telerik RadListBox 不想拖动

Question

在我的 asp.net 解决方案中，我尝试使用列表框拖放功能(如本例所示:http://demos.telerik.com/aspnet-ajax/listbox/examples/functionality/draganddrop/defaultcs.aspx)。但我现在遇到的问题是拖放不起作用。而不是拖动它的标记项目...我试图将 html 直接复制到我的页面，但它仍然不起作用。有什么想法可能是错误的吗？

是因为我想念 CSS 吗？

您是否尝试过用 RadScriptManager 替换您的标准 ScriptManager？
