当点击对话框中的aspx按钮时，Jquery对话框不会关闭

我们在点击网格行时调用jquery对话框：

   protected void grdVendorContactDetails_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
e.Row.Attributes.Add("onclick", "displayContact('" + objlbl.Text + "')");
 }
  }

我的jquery对话框代码：

 function displayContact(ID) {
        var page ='VendorDetailsValidation.aspx?Id=' + ID  //get url of link
        var $dialog = $('<div></div>')
            .html('<iframe style="border: 0px; " src="' + page + '" width="100%" height="100%"></iframe>')
          .dialog({
                autoOpen: false,
                modal: true,
                height: 650,
                width: 800,
                title: "Validation Details",
                buttons: {
                    "Close": function () {
                        $(this).dialog("close");
                    }
                }

            });
                     $dialog.dialog('open');
    }

我的Venodordetails aspx页面：

点击保存按钮，我必须关闭我的jquery对话框：我使用了以下代码，但没有工作：

 protected void btnSave_Click(object sender, EventArgs e)
{
   string id = Request.QueryString["Id"].ToString();
    obj.Type = ddlType.SelectedValue;
    obj.ContactName = txtContactName.Text;
    obj.Product = txtProduct.Text;
    obj.Responsibility = ddlResponsibility.SelectedValue;
    obj.Platform = ddlPlatform.SelectedValue;
    obj.LOB = txtLob.Text;
    obj.Office = txtOffice.Text;
    obj.Mobile = txtMobile.Text;
    obj.Pager = txtPager.Text;
    obj.Hotline = txtHotline.Text;
    obj.Emailid = txtEmail.Text;
    obj.Pin = txtPin.Text;
    obj.Status = rblStatus.SelectedValue;
   obj.Notes = txtNotes.Text;

    obj.SaveVendorDetails(id);
 ScriptManager.RegisterStartupScript(this,GetType(), "tmp", "<script type='text/javascript'>Confirm();</script>",false);
 }

  function Confirm() {
                    $(this).dialog('close');
                 }

当我尝试像上面那样关闭时，我遇到了错误。请告诉我如何关闭对话框。我得到的$（this）.val（）为未定义或空
