Printing IFrame is printing whole window contents

    Here is the problem, guyz

    In the chat transcripts section you can print chat transcript from two

    1) ChatTranscript.aspx (All the chat topics are there you
    can click on print button and you can print specific topic)

    2) DisplayChatTranscript.aspx (After clicking on the chat
    topic it opens up the chat and you can click print button and print
    that chat)

    They both have an IFrame which opens up PrintChatTranscript.aspx and
    This file prints itself by using "window.print" on "body onload" event.

    Now the problem is when we print through ChatTranscript.aspx it prints
    its own screenshot instead of printing Contents in the IFrame which is

    But the DisplayChatTranscript.aspx works fine and prints the Contents
    from IFrame which is PrintChatTranscript.aspx

    I did some research and what i came up with is.

    When we print from ChatTranscript.aspx file. It sets IFrame location to
    PrintChatTranscript.aspx which prints itself.

    Now in PrintChatTranscript.aspx when i did the research i came to know
    that PrintChatTranscript is not able to access IFrame object. when i
    tried accessing it through

    top.window.IFramename.focus( );

    It gives me error "Jscript Runtime Error Permission Denied"

    Another file has the same code and its able to print the IFrame
    contents. All 3 files are in the same folder so there is not security

    Moreover when it says Iframe.location="PrintChatTranscript.aspx" it
    loads the contents into it.

    But when PrintChatTranscript.aspx says "window.print" it prints the
    whole window because its not able to access the IFrame object. Its not
    existing in the Object Hierarchy.

    Can Anybody Help ?? will really Appreciate that. i am stucked on this
