Confused about databinding and event order

Newbie here, so be gentle.

I've tried writing this page a variety of ways, but can't get this to
work.

I have a drop down with monetary exchange rates.
I have a table with a bunch of columns (>20) being returned.
I bind the table to a FormView.

Wonderful

Now, I want to modify the dollars by multiplying it with the exchange
rate value. So I wrote a property function:

ReadOnly Property getCurrency() As String
Get
Dim curr As String
Dim dd As DropDownList

dd = FormView1.FindControl("currency_code")
curr = dd.SelectedItem.ToString

Return curr
End Get
End Property

For giggles (and testing) I have a label control which normally would
be databound, but since it wasn't working, I'm just displaying the
value of getCurrency() (which is why getCurrency is now returning a
string)

<asp:Label ID="Label1" runat="server" Text='<%# getCurrency()
%>'></asp:Label>

What happens is that the Label1 gets populated the first time, but as I
change the dropdown value, it's as if getCurrency never runs again. I
don't get it.
 
databinding happens when you call databind. you should re-databind the
label after a change in dropdown.
