我知道这是一个争议很大的话题，通常在您将其作为解决方案考虑时，您可能需要重新考虑UI逻辑.

I know this is a very debated topic, and usually when you are thinking about this as a solution you might want to rethink your UI logic.

我知道我可以使用ClientScriptManager.RegisterForEventValidation通过验证.但是，我真的很想知道.是否可以删除单个控件的事件验证?有办法解决这个问题吗?

I know I can pass validation using ClientScriptManager.RegisterForEventValidation. But, I'd really like to know. Is it possible to remove event validation for a single control? Is there a way work around for this?

我正在渲染呈现后从客户端修改DropDownList.

I'm modifying a DropDownList, from the client side after it's rendered.

推荐答案

您的问题的简短答案是:不，没有办法这样做.您必须为整个页面禁用EventValidation.

The short answer to your question is: No, there is no way to do this. You must disable EventValidation for the entire page.

有多种解决方法...如果您确实不想禁用EventValidation，则将选定的值存储在隐藏字段中并恢复DropDownList的状态(或者也许只是清除选择?).

There are various workarounds... If you really don't want to disable EventValidation, store the selected value in a hidden field and restore the state of the DropDownList (or maybe just clear selection?).

如果需要在客户端添加所有的值，则无论如何都必须使用其他方法将其发送出去，因为它们不会出现在服务器端控件中.这些值未发布！

If you need all the values added client-side, you have to send those up using some other method anyway, because they will not be present in the server-side control. Those values are not posted!
