title: Update on GridView combobox not updating
body: <p>I am trying to bind the DropDownList(DDL) with my entity datasource. The GridView(GV) is bound to a different EntityDataSource than the DDL. The GV's EntityDataSource has a navigation property 'Bag' for the relationship. In edit mode I can pick a different item, but it does not update the database for that record. I did use the <em>include</em> for the navigations in the EntityDataSource. I am sure the wiring is not correct. I have tried searching with no luck so far. Thanks for the help.</p>
  
  <pre><code>&lt;asp:TemplateField HeaderText="Bag"&gt;
    &lt;ItemTemplate &gt;
      &lt;asp:Label ID="lbEditBag" Text='&lt;%#Eval("Bag.Item1") %&gt;' runat="server" /&gt;
    &lt;/ItemTemplate&gt;
    &lt;EditItemTemplate &gt;
      &lt;asp:DropDownList runat="server" ID="ddlBags" DataSourceID="edsBags" DataTextField="Amount" DataValueField="BagId" /&gt;
    &lt;/EditItemTemplate&gt;
  &lt;/asp:TemplateField&gt;
  </code></pre>
