Answer 1

Try this javascript on the button click.

HTML

<input type="hidden" id="txtHidData" runat="server" />

Javascript

var iframe = document.getElementById('iframebody');
var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
var usernameTextBox = innerDoc.getElementById('txtfromdate');
document.getElementById ( "txtHidData" ).value = usernameTextBox.value;

C#

string valueInCodeBehind = txtHidData.Value;
