First ID to the iframe, like

XML

<iframe id="Data" name="Data" src="" style="display: none"></iframe>

JavaScript:

JavaScript

var frameDocument = document.getElementById('Data').contentWindow().document;

using frameDocument you can access anything in the iframe.

You cannot access the controls inside the iframe from the code-behind (C#). The content inside the IFrame is altogether a new Page which cannot be accessed from another page.

You can access using JavaScript and assign the values in a HiddenField (runat Server) and use it from the CodeBehind (C#)
