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.

3:我改变了我的按钮类型在网格列从“PushButton”到 “LinkButton”。它工作! ("ButtonType="LinkButton")我认为如果你可以把你的按钮换成其他的其他控件如“LinkButton” 在这种情况下，它会正常工作。

我希望我能给你投票，阿米尔(唉，我的代表太低了。)我只是有这个问题，改变这个工作就像一个冠军在我的网格视图。稍微提一下，我认为有效的代码是:ButtonType="Link"

我怀疑这是因为当你点击“编辑”时，你的编辑变成了“更新”和“取消”，然后在提交时又变成了“编辑”。这些变化的控件让。net很不舒服。

其他回答

如果您通过客户端脚本填写下拉列表，则在将表单提交回服务器之前清除列表;然后ASP。NET将不会抱怨，安全性将仍然存在。

为了从DDL中获得选择的数据，您可以将“OnChange”事件附加到DDL以收集隐藏输入或文本框中的值，并使用Style="display: none;"

对我有用的是将以下代码从page_load移动到page_prerender:

lstMain.DataBind();
Image img = (Image)lstMain.Items[0].FindControl("imgMain");

// Define the name and type of the client scripts on the page.
String csname1 = "PopupScript";
Type cstype = this.GetType();

// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;

// Check to see if the startup script is already registered.
if (!cs.IsStartupScriptRegistered(cstype, csname1))
{
    cs.RegisterStartupScript(cstype, csname1, "<script language=javascript> p=\"" + img.ClientID + "\"</script>");
}

我也遇到过同样的问题

刚刚添加了一个条件if(!IsPostBack)，它工作得很好:)

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();
        }

此错误将在没有回发的情况下显示

添加代码:

If(!IsPostBack){

 //do something

}

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