title: ListView with LINQ Datasource insert template
body: <p>It seems like this should be straightforward but I'm boggling.  I've got my listview all setup and bound to my LINQ datasource.  The source is dependent on a dropdown list which decides which branch information to show in the listview.  My edit template works fine but my insert template won't work because it wants the branch ID which I want to get from the dropdownlist outside the listview but I don't know how to both bind that value and set it in my template.  It looks like this:</p>
  
  <pre><code>&lt;InsertItemTemplate&gt;
      &lt;tr style=""&gt;
        &lt;td&gt;
           &lt;asp:Button ID="InsertButton" runat="server" CommandName="Insert" 
                 Text="Insert" /&gt;
       &lt;/td&gt;
        &lt;td&gt;
         &lt;asp:TextBox ID="RechargeRateTextBox" runat="server" 
            Text='&lt;%# Bind("RechargeRate") %&gt;' /&gt;
           &lt;/td&gt;
                &lt;td&gt;
         &lt;asp:Calendar SelectedDate='&lt;%# Bind("StartDate") %&gt;' ID="Calendar1"  runat="server"&gt;&lt;/asp:Calendar&gt;                                    
         &lt;/td&gt;
             &lt;/tr&gt;
      &lt;/InsertItemTemplate&gt;
  </code></pre>
  
  <p>I need to get a label in there that binds to the value of a databound asp dropdownlist outside of the listview so that the insert will work.</p>
