Hi friends,
I have page which uses master page, it has following
1. user control(ucMessage)
2. Iframe(frmrevrec)

What I want is, from iFrame i want to make the control visible property to true set value of user control in parent page using jquery.

I tried following in iFrame:

C#

$(document).ready(function () {
                var obj = $('#tblMessage').find('#ucMessage');
                var obj1 =
                if ($('#ucMessage').style.display == 'none') {
                    alert(obj + "hi");
                    obj.style.display = 'block';
                }
                $('tblMessage').find('#ucMessage').value = 'Hi';
            });

But it is not working fine.

This is aspx for parent page

<asp:Content ID="Content1" ContentPlaceHolderID="cphPage" runat="server">
      <asp:UpdatePanel ID="pnlUpdateMessage" runat="server" UpdateMode="Conditional">
        <contenttemplate>
            <table id="tblMessage" style="width: 100%">
                <tr>
                    <td>
                        <uc:ucmessage_ascx ID="ucMessage"  runat="server" />
                    </td>
                </tr>
            </table>
        </contenttemplate>
    </asp:UpdatePanel>
        <iframe id="frmrevrec" src="wf_ProjectEstimates.aspx" width="100%" scrolling="no" frameborder="0" height="100px"></iframe><br />
</asp:Content>

Any idea how to go about it??

Thanks in advance

Here is what I did
Parent Page JavaScript:

<script type="text/javascript">
        function setMessage(strMsg) {
            document.getElementById('<%= lblMessage.ClientID%>').innerHTML = strMsg;
        }
</script></script>

And this is how i called it through the iFrame

<script>
 top.setMessage('hello');
</script>

And it working fine :)
