Question

Very famous error message (see below), judging by the number of Google results. But every one of them I ve seen suggests to set EnableEventValidation to false. I have searched my entire codebase, and I cannot find the string "EnableEventValidation" anywhere. Moreover, this code used to work; something I have done has obviously broken the pages. But what?

当我点击Telerik RadGrid的一顿时,该错误发生:

<telerik:RadGrid ID="MyGrid" Width="100%" ItemStyle-BorderColor="Gainsboro"
ItemStyle-BorderStyle="Solid" ItemStyle-BorderWidth="1px" ActiveItemStyle-BackColor="Bisque"
SelectedItemStyle-BackColor="Black" AllowPaging="True" PageSize="15" runat="server"
AllowSorting="true" OnItemCommand="MyGrid_ItemCommand" AutoGenerateColumns="false"
OnNeedDataSource="MyGrid_NeedDataSource" GridLines="Horizontal" AllowMultiRowSelection="false"
Skin="Black">
  <GroupingSettings CaseSensitive="false" />
  <MasterTableView Width="100%" DataKeyNames="ID" AllowFilteringByColumn="false" Font-Names="Arial"
  Font-Size="10px">
    <Columns>
      <telerik:GridButtonColumn ButtonType="PushButton" Text="Cancel" CommandName="Cancel"
      ConfirmText="Are you sure you want to cancel this?">
      </telerik:GridButtonColumn>
      ...
    </Columns>
  </MasterTableView>
  <PagerStyle Mode="NextPrevAndNumeric" />
  <FilterMenu EnableTheming="True">
    <CollapseAnimation Duration="200" Type="OutQuint" />
  </FilterMenu>
</telerik:RadGrid>

点击“Cancel”纽吨,这里引出了著名的错误:

<编码> 无效的背后或背叛论点。活动验证使用“带”;页面使EventValidation=“true”/> 配置或设计;%@p EnableEventValidation=“true” %> 网页。为了安全起见,这一特点证明,关于退税或退税事件的论据源自服务器控制,而服务器控制最初正是这样。如果数据有效且预期,则使用《客户手册》。登记通风方法,以便登记回馈或回数据以供验证。

Answer 1

这里的问题是:在我的<编码>中。页: 1 方法一:

protected void Page_Load(object sender, EventArgs e) {
  MyGrid.Rebind();
}

输电网的重新约束力显然使一些东西化为乌有。我改为:

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

and everything is working now.

Answer 2

我也存在同样的问题,但我没有在我的需要DataSource方法或Load方法中找到Grid.Rebind()或Grid.Databind()。这发生在我rag一栏被归类之后,然后命令将ASC/DESC栏归类。

我简单地补充说:

EnableEventValidation="false"

页: 1 页: 1 命令失败,但至少我不再犯错误。值得一提的是,除组别一栏的次序外,所有其他工作都是完美的。

这里使用的是《需要数据方法》中的代码一。

        protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        String connstr = ConfigurationManager.ConnectionStrings["PrimeIntegartionsConnectionString"].ConnectionString;

        SqlDataSource Ds = new SqlDataSource(connstr, BuildSql()); //buildsql simply returns a SQLSelect String "select * from example"
        RadGrid1.DataSource = Ds;
    }
