我有问题要禁用/启用验证器以在更新面板中向 gridview 新添加行，如果我删除更新面板，那么它工作完美，如果我添加更新面板，那么它停止工作。我已经创建了示例页面。

默认.aspx。

<head>     <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"></script>     <script type="text/javascript">        $(document).ready(function () {            $('table > tbody > tr .wrapper [class*="onoff"] option:selected').each(function (index) {                adjustValidators(this);            });            $('[class*="onoff"] select').change(function () {                adjustValidators($('option:selected', this)[0]);            });        });                    </script></head>

默认.aspx.cs。

 protected void Page_Load(object sender, EventArgs e)
{
    MultiView1.ActiveViewIndex = (MultiView1.ActiveViewIndex == -1) ? 0 : MultiView1.ActiveViewIndex;

    DataTable objData =new DataTable();
    if (ViewState["data"] != null)
    {
        objData = (DataTable)ViewState["data"];
    }
    else
    {
        objData = new DataTable();
        objData.Columns.Add("testsssss");
        objData.Columns.Add("ONOFF");
        objData.Columns.Add("ONOFF_selectedValue");
        objData.Rows.Add(objData.NewRow());
        ViewState["data"] = objData;
    }

    if (!IsPostBack)
    {
        repeatregion_RRSectionSS.DataSource = objData;
        repeatregion_RRSectionSS.DataBind();
    }

}
protected void btnNext_Click(object sender, EventArgs e)
{
    MultiView1.ActiveViewIndex += 1;
}

protected void btnPrevious_Click(object sender, EventArgs e)
{
    MultiView1.ActiveViewIndex -= 1;
}

protected void btn_Click(object sender, EventArgs e)
{
    DataTable objData = (DataTable)ViewState["data"];

    objData.Rows.Add(objData.NewRow());
    repeatregion_RRSectionSS.DataSource = objData;
    repeatregion_RRSectionSS.DataBind();
    ViewState["data"] = objData;
}

当点击添加然后项目被添加到gridview但验证器没有被禁用。

经过一些研究和诡计，我找到了解决方案：替换eval为 . 它对我有用。ValidatorEnable(eval(id), false)document.getElementById(id)
