Answer 1

You maybe can store it in a Session-variable?

Answer 2

Why don't you just pass the value as a parameter in your call to open pageB.aspx?

<a href="javascript:void(0)"
    onclick="window.open('pageB.aspx?param=' +
 document.getElementById('textBoxFromPageA').value,
        'Add','width=700,height=400')">
        Add</a>

This will generate the URL of pageB.aspx?param=Apple. Then on the pageB.aspx code behind, you can access that value using the Request("param") call.

As an alternative to query string or session consider using the PreviousPage property or using server.transfer and then getting a handle to the previous page through context.handler.

Doing this is beneficial in that session is not utilised needlessly and query string parameters: visible, editable, hackable by all of the world are not used.
