当我将图像上传到图像控件时，出现以下错误 [英] when i am uploading an image to the image control i am getting the following error

问题描述

无效的回发或回调参数.使用< pages enableeventvalidation ="true">启用事件验证.在配置中或<％@页面EnableEventValidation ="true"％>在页面中.为了安全起见，此功能验证回发或回调事件的参数源自最初呈现它们的服务器控件.如果数据有效且预期，请使用ClientScriptManager.RegisterForEventValidation方法以注册回发或回调数据以进行验证.

为什么我收到此错误

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.

why i am getting this error
