Does Bind() retrieve a value moments before…?

Question

Hi

If user selects another item in ddlJobs, then I assume for Bind() to be able to retrieve the newly selected value, SelectedIndexChangedEvent needs to be fired before Bind() tries to retrieve the value of ddlJobs.SelectedValue property?

So when exactly does Bind() retrieve a value from binded property? Moments before the updating begins and not before?

   <EditItemTemplate>
      <asp:DropDownList ID="ddlJobs" runat="server" 
            SelectedValue='<%# Bind(“JobTitle”) %>'>
      </asp:DropDownList>
   </EditItemTemplate>

thanx
