c# - 系统参数异常 : Invalid postback or callback argument

Question

Server Error in '/WebSite10' Application. Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

我弄错了。

请注意:我确实会动态生成一些控件并调用它们的事件。为什么会发生这种情况，我该如何预防？

Answer 1

您需要在每个 page_load 上动态地重新生成这些控件。即使在回传上。您还需要每次都将它们的 Id 设置为相同的值。
