update GridView BoundFields using ObjectDataSource

Question

I have a GridView and I would like to edit/update rows using a custom method in my ObjectDataSource. I can get this to work using auto-generated columns but not BoundFields which is what I need. I have tried doing GridView1.DataBind() in the RowUpdated, RowUpdating, and RowEditing events. I don't get an error message. It just doesn't update the row.

IncidentUpdate.aspx

<asp:GridView ID="GridView1" runat="server" DataSourceID="ObjectDataSource2" AutoGenerateColumns="false">
    <Columns>
        <asp:CommandField ShowEditButton="True" />
        <asp:BoundField DataField="IncidentID" HeaderText="ID" ReadOnly="True" />
        <asp:BoundField DataField="ProductCode" HeaderText="Product Code"  ReadOnly="True" />
        <asp:BoundField DataField="DateOpened" HeaderText="Date Opened"  ReadOnly="True" />
        <asp:BoundField DataField="DateClosed" HeaderText="Date Closed" />
        <asp:BoundField DataField="Title" HeaderText="Title"  ReadOnly="True" />
        <asp:BoundField DataField="Description" HeaderText="Description" />
    </Columns>
</asp:GridView>
<asp:ObjectDataSource ID="ObjectDataSource2" runat="server" SelectMethod="GetCustomerIncidents" TypeName="IncidentDB" UpdateMethod="UpdateIncident">
    <SelectParameters>
        <asp:ControlParameter ControlID="DropDownList1" Name="customerID" PropertyName="SelectedValue" Type="Int32" />
    </SelectParameters>
    <UpdateParameters>
        <asp:Parameter Name="incidentID" Type="Int32" />
        <asp:Parameter Name="dateClosed" Type="DateTime" />
        <asp:Parameter Name="description" Type="String" />
    </UpdateParameters>
</asp:ObjectDataSource>

App_Code\Service.cs

 public static DataSet UpdateIncident(int incidentID, DateTime dateClosed,string description)
 {
    TechSupportDB techSupportDB = new TechSupportDB();
    var myConnection = techSupportDB.GetConnectionString();

    SqlCommand myCommand = new SqlCommand();

    myCommand.Parameters.AddWithValue("@IncidentID", incidentID);
    myCommand.Parameters.AddWithValue("@DateClosed", dateClosed);
    myCommand.Parameters.AddWithValue("@Description", description);
    myCommand.CommandText = 
    "update Incidents set DateClosed = @DateClosed, Description = @Description where IncidentID = @IncidentID";

    myCommand.Connection = myConnection;
    SqlDataAdapter myAdapter = new SqlDataAdapter(myCommand);
    DataSet updatedIncidentsDataSet = new DataSet();
    myAdapter.Fill(updatedIncidentsDataSet);
    return updatedIncidentsDataSet;
}

Answer 1

The BoundField for IncidentID is set as readOnly so the user cannot edit this field but this also prevents it from passing the value necessary to do the update. Solution: set DataKeyNames = IncidentID in the GridView.

 <asp:GridView ID="GridView1" runat="server" DataSourceID="ObjectDataSource2"
  AutoGenerateColumns="False" DataKeyNames="IncidentID">
