What I want to do seems so simple, yet I can't figure it out! I have
a very simple aspx page that I'm displaying in an Iframe. The page
has three dropdown boxs and I this code on the aspx.cs to set three
variables to the selected text.

public partial class _Default : System.Web.UI.Page
{
public static string SelectedTopSector;
public static string SelectedSubSector;
public static string SelectedFinalSector;

protected void TopSector_SelectedIndexChanged(object sender,
EventArgs e)
{
SelectedTopSector = TopSector.SelectedItem.Text;
}
protected void SubSector_SelectedIndexChanged(object sender,
EventArgs e)
{
SelectedSubSector = SubSector.SelectedItem.Text;
}
protected void FinalSector_SelectedIndexChanged(object sender,
EventArgs e)
{
SelectedFinalSector = FinalSector.SelectedItem.Text;
}
}

I want to access these variables from javascript in order to pass the
values back to my parent form. My code is correct (see below) for
passing the variable back as I can pass static values, but I cannot
seem to figure out how to get pass the variables from the C# code.

<script type="text/javascript" language="javascript">
// Assign back to the form
parent.document.forms[0].all.topsector.DataValue =
SelectedTopSector;
parent.document.forms[0].all.subsector.DataValue =
SelectedSubSector;
parent.document.forms[0].all.finalsector.DataValue =
SelectedFinalSector;
</script>

PLEASE PLEASE PLEASE if someone could help me understand what I'm
missing I would appreciate it tremendously!!

The problem is that you're setting server side variables, and then accessing
them via javascript (client side). Remove the event handlers, (you dont need
them), and just pass the values back by accessing the dropdown values
directly in javascript.

Can you give me any direction on accessing the value from javascript?
I have tried using getelementbyid and I just get an objectrequired
error.

Thanks!
