[英]DropDownList OnSelectedIndexChanged does not fire
I have MVC4 Web application and i am rendering a partial view(.ascx) inside a .cshtml page. 我有MVC4 Web应用程序,并且正在.cshtml页面中渲染部分视图(.ascx)。 I have added a dropdownlist which has OnSelectedIndexChanged and it never fires.
我添加了一个具有OnSelectedIndexChanged的dropdownlist,它从不触发。 please see the code below
请参见下面的代码
