请给我快速回复

Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> 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.

推荐答案

在Page_Load中完成绑定时，ScriptManager可能找不到控件，而在Page_PreRender中将数据控制到控件（如数据集）将解决问题。

ScriptManager may not find the control when binding is done in Page_Load instead bining the data to control (like dataset) in Page_PreRender will solve the issue.

尝试对页面执行EnableEventValidation = false有这个问题。



此外，请确保您的Web.Config文件使用Ajax脚本。

此外，请确保 - 启用Scriptmanagers部分渲染

Try having EnableEventValidation = false for the page you are having this issue.

Further, make sure your Web.Config file is up with Ajax scripts.
Also, make sure - Scriptmanagers partial rendering is enabled

您可以按照错误消息的建议进行操作并使用 ClientScriptManager.RegisterForEventValidation [ ^ ]方法，以便注册回发或回调数据进行验证。



或者你可以只是将页面的EnableEventValidation设置为false。

You could do as the error message suggests and use the ClientScriptManager.RegisterForEventValidation[^] method in order to register the postback or callback data for validation.

Or you could just set EnableEventValidation for the page to false.
