how to access fields with visible = "false" with jquery?

Question

I have this fields, with visible = "false" I can access it via the cs page in backend, but how can I acess this control with jquery? I little code might help..

<tr>
  <td class="TDCaption" style="text-align: left">
    <asp:Label ID="lblMsg" runat="server" EnableViewState="False" ForeColor="#CC0000"></asp:Label>
    <div class="DivStyleWithScroll" style="width: 100%; overflow: scroll; height: 250px;">
      <asp:GridView ID="grdReport" runat="server" AutoGenerateColumns="False"
      DataKeyNames="CustCode" ShowFooter="True" EmptyDataText="No record found"
      PageSize="50" CssClass="mGrid" onrowdatabound="grdReport_RowDataBound">
        <Columns>
          <asp:TemplateField Visible="false">
              <ItemTemplate>
                  <asp:Label ID="lblCustCodes" runat="server" Text='<%# Eval("CustCode") %>' CssClass="grdCustName"></asp:Label>
              </ItemTemplate>
          </asp:TemplateField>
          <%--other columns--%>

The jquery is

 $('#<%=btnCompare.ClientID%>').click(function () {
            if ($(':checkbox:checked').size() == 0) {
            }
            else {
                custList = $(':checkbox:checked').map(function () { return $(this).closest('tr').find('.grdCustName').text() }).get();
                alert(custList);
            }
    });

I think I'm right in thinking that .Visible = false will stop the control from being rendered in the HTML. Have you checked the HTML source sent to the browser? — freefaller

I believe setting .Visible = false will stop the control from being rendered into the HTML, so the jQuery will simple not be able tofind it.

Instead, for code-behind, try using...

ctrl.Style("display") = "none"

Or on the markup, try using the following attribute on the control...

style="display:none"

If Visible is false, then the control did not go down to the client, so you cannot directly access it from javascript/jquery: it simply isn't there. you can put the control's value in some hidden field and then can access it. as they are never visible in frontend. Hiddenfields are visible only in HTML source.

Label.ForeColor = System.Drawing.Color.Transparent in code behind

then set the Label Visible to true
