Please take a look at this link:
i added this in form tag and the parent page refreshes:
<form id="form1" runat="server" onsubmit="parent.location.
the only problem it's showing is that if the form is not yet filled then the page reloads with the new data in the dropdown without any hitches....but if there's data on the parent page, then on refresh, either the data stays intact but the new data does not get inserted in the dropdown OR the data disappears.
any idea why this is happening? and solution?
