Linq to SQL gridview edit function not working

Gridview

ASP.NET4

C#6.0

I have a gridview with an edit Commandfield. It is bound to table Asset_Portfolio. Works fine. I click on EDIT, it gives me UPDATE and CANCEL links. I input a few exposed fields and click UPDATE. It updates.

Now I add a couple dropdowns on the panel outside of the gridview. I populate them and when the user clicks on a row, it sends that row to the gridview where. That part works great. However, the dropdowns are somehow preventing the Gridview from allowing an EDIT. I click on EDIT, the text boxes appear, but it won't let me enter any data.
I played around with this a bit and discovered that before the dropdowns are bound, the EDIT works correctly. Once the DataBind command executes, the gridview is broken.

Can someone please help me? No idea.

What I have tried:

<asp:GridView ID="GridView1" runat="server" AllowPaging="True"  PageSize="37" AllowSorting="True"
      AlternatingRowStyle-BackColor="#99CCFF"
      DataSourceID="dsPortfolio" AutoGenerateColumns="False"
      DataKeyNames="Asset_Id" OnRowDataBound="OnRowDataBound" OnRowUpdating="OnRowUpdating"
      EnableUpdate="true"
      Height="100%"
      Width="100%">
      <AlternatingRowStyle BackColor="#cccccc" />


      <Columns>
                     <asp:CommandField ShowEditButton="True"

          ButtonType="Link" EditText="EDIT"
          UpdateText="UPDATE"
          CancelText="CANCEL">
      </asp:CommandField>

          <asp:BoundField DataField="Asset_Id" HeaderText="ID" ReadOnly="True" SortExpression="Asset_Id" ItemStyle-Width="10px"/>
           <asp:BoundField DataField="As_Of_Date" HeaderText="AsOf" ReadOnly="True" SortExpression="As_Of_Date" ItemStyle-Width="200px"/>
          <asp:BoundField DataField="Loan_Number_Display" HeaderText="Loan #" ReadOnly="True" SortExpression="Loan_Number_Display" ItemStyle-Width="100px"/>
          <asp:BoundField DataField="Entity_Name" HeaderText="Name" ReadOnly="True" SortExpression="Entity_Name" ItemStyle-Width="200px"/>

SqlDataAdapter da2 = new SqlDataAdapter("select distinct loan_number_display from libor.Droploan order by loan_number_display", Conn3);
  DataSet ds2 = new DataSet();
  da2.Fill(ds2);
  if (ddlLoan != null)
  {
      ddlLoan.DataSource = ds2;
      ddlLoan.DataTextField = "Loan_number_display";
      ddlLoan.DataValueField = "Loan_number_display";
      ddlLoan.Items.Insert(0, new ListItem("Select"));
      ddlLoan.DataBind();

  }
  da2.Dispose();
  ds2.Dispose();
