ASP.NET 母版页：事件验证错误

发布于 2024-07-26 07:56:18 字数 597 浏览 8 评论 0原文

我在我的主页中包含了一个中继器。中继器有一个按钮，我可以设置它的 CommandArgument。

但是，当我单击该按钮时，出现以下异常：

System.ArgumentException：无效的回发或回调参数。使用配置或 <%@ Page EnableEventValidation="true" %> 启用事件验证在一个页面中。出于安全目的，此功能验证回发或回调事件的参数是否源自最初呈现它们的服务器控件。如果数据有效且符合预期，请使用 ClientScriptManager.RegisterForEventValidation 方法注册回发或回调数据以进行验证。

并且它不会继续到事件处理程序。

笔记：我尝试将这些行添加到母版页，但没有帮助：

protected override void Render(HtmlTextWriter writer)
{
    Page.ClientScript.RegisterForEventValidation(rptrLanguages.ClientID);
    base.Render(writer);
}

谢谢。

原文

I included a repeater in my master page.
The repeater has a button that I set its CommandArgument.

However when I click the button I get the following exception:

System.ArgumentException: 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.

And it doesn't continue to the event handler.

Note:
I tried adding these lines to the master page but it doesn't help:

protected override void Render(HtmlTextWriter writer)
{
    Page.ClientScript.RegisterForEventValidation(rptrLanguages.ClientID);
    base.Render(writer);
}

Thanks.
