I'm trying to accomplish the equivalent of the code below, but with a
two-way data binding.  GetReportsTo() will just return a default
selection in the case of a NULL DB entry.  I thought I could just
replace Eval with Bind, but that gives me: "The name 'Bind' does not
exist in the current context."

Is it possible to do this in the control, or do I need to modify the
DataSource?

<EditItemTemplate>
   <asp:DropDownList ID="DropDownList2" runat="server"
       DataSourceID="SqlDataSource2" DataTextField="Name"
       DataValueField="EmployeeID"
       SelectedValue='<%# GetReportsTo(Eval("ReportsTo")) %>'
       AppendDataBoundItems="True">
           <asp:ListItem Selected="True" Value="0">(none)</
asp:ListItem>
   </asp:DropDownList>
</EditItemTemplate>
