I have issue to disable/enable validators for newly add row to gridview which is in Update panel, If I remove Update panel then it's worked perfect, and If I add Update panel then it stops working. I have created sample page.
Default.aspx的。
Default.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>

<script type="text/javascript"> function pageLoad(sender, args) { if (args.get_isPartialLoad()) { $('table > tbody > tr .wrapper [class*="onoff"] option:selected').each(function (index) { adjustValidators(this); }); } } function adjustValidators(ctrl) { var id = ctrl.parentNode.id.replace('_question', '_rfv_question').replace('ONOFF', 'testsssss') // alert(ctrl.value); if (ctrl.value == -1) { ValidatorEnable(eval(id), false) } else { ValidatorEnable(eval(id), true) } } </script>
Default.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;
}
在单击添加然后项目被添加到GridView的验证，但未被禁用。
when Click on add then item get added to gridview but validators are not disabled.

推荐答案
一些重新搜索和招我有ValidatorEnable（EVAL（ID），假）通过document.getElementById（id）的解决方案改变后的eval，它的工作过我的。
After some re-search and trick I have solution change eval in ValidatorEnable(eval(id), false) with document.getElementById(id) and it's worked for me.
