无效的回发或回调参数。使用'<pages enableEventValidation="true"/>'启用事件验证

当我从客户端返回一个页面时，我得到以下错误。我有JavaScript代码，修改asp:ListBox在客户端。

我们如何解决这个问题?

错误详情如下:

Server Error in '/XXX' Application.

这里没有提到的另一种方法是子类化ListBox

Ie.

public class ListBoxNoEventValidation : ListBox 
{
}

如果你子类化了system . web . ui . supportsevenvalidation属性，除非你显式地把它添加回来，否则它永远不会调用验证例程。这对任何控件都有效，而且是我发现的在一个控件的基础上“禁用”它的唯一方法(即，不是页面级别)。

Ajax UpdatePanel可以做到这一点，我认为这是最简单的方法，忽略Ajax回发开销。

在本例中，将id添加到网格的RowDataBound中的按钮。它会解决你的问题。

这个问题的一个简单解决方案是在页面加载时使用IsPostBack检查。这样问题就解决了。

如果您正在使用gridview，而不是在pageload inside !ispostback中绑定gridview，那么当您单击gridview中的编辑和删除行时，将出现此错误。

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
        bindGridview();
        }

如果您使用Ajax更新面板。添加<Triggers>标签，并在其中使用<asp:PostBackTrigger…/>触发按钮或控件导致回发
