[Mugdha_Aditya]

i have frame.aspx page on which i have frame plus hidden feild.
from which am calling another page.
in that anothe page i want to access hidden feild control of frame.

Below is my design page of frame.aspx
<form id="formFrame" runat="server">
<table width="100%" cellpadding="0" cellspacing="0">
<tr valign="top">
<td align="center" valign="top">
<iframe id="iFrame" name="MainFrame" runat="server" width="940px" height="785px" scrolling="no" frameborder="0" >

            </iframe>
             <asp:HiddenField ID="hdnCulture" runat="server"/>
        </td>
    </tr>
</table>
</form>

Below is my frame.aspx.cs code

iFrame.Attributes["src"] = "Default.aspx?ticker=" + sTicker "";

So i want to access hdnCulture control on default.aspx page.
