Add new Item and Edit Item in silverlight DataForm not correctly updating SharePoint List - silverlight-4.0

Question

I am trying to make a simple Silverlight application that will be hosted on a SharePoint site.
I am reading the information from the list "testlist" and I am trying to use a dataform control to edit, add and delete data from the list. I am able to delete just fine. When I try to add it adds a new entry with the data from the item previously viewed and I am unable to edit current Items whatsoever. Here is my code:
namespace SP2010
{
public partial class MainPage : UserControl
{
ClientContext context;
List customerList;
ListItemCollection allCustomers;
public MainPage()
{
this.Loaded += new RoutedEventHandler(MainPage_Loaded);
InitializeComponent();
}
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
this.DataContext = this;
context = new ClientContext(ApplicationContext.Current.Url);
customerList = context.Web.Lists.GetByTitle("testlist");
context.Load(customerList);
CamlQuery camlQuery = new CamlQuery();
camlQuery.ViewXml =#"<View><Query></Query><RowLimit>1000</RowLimit></View>";
allCustomers = customerList.GetItems(camlQuery);
context.Load(allCustomers);
context.ExecuteQueryAsync(new ClientRequestSucceededEventHandler(OnRequestSucceeded), new ClientRequestFailedEventHandler(OnRequestFailed));
}
private void OnRequestSucceeded(Object sender, ClientRequestSucceededEventArgs args)
{
Dispatcher.BeginInvoke(DisplayListData);
}
private void OnRequestFailed(Object sender, ClientRequestFailedEventArgs args)
{
MessageBox.Show(args.ErrorDetails + " " + args.Message);
}
public ObservableCollection<SPCustomers> Printers
{
get
{
if (printers == null)
{
printers = new ObservableCollection<SPCustomers>();
foreach (ListItem item in allCustomers)
{
printers.Add(new SPCustomers
{
IPAddress = item["Title"].ToString(),
Make = item["make"].ToString(),
Model = item["model"].ToString(),
xCord = item["x"].ToString(),
yCord = item["y"].ToString(),
id = Convert.ToInt32(item["ID"].ToString())
});
}
}
return (printers);
}
}
private ObservableCollection<SPCustomers> printers;
private void DisplayListData()
{
dataForm1.DataContext = Printers;
}
private void dataForm1_EditEnded(object sender, DataFormEditEndedEventArgs e)
{
if (e.EditAction == DataFormEditAction.Commit)
{
if (dataForm1.IsItemChanged)
{
customerList = context.Web.Lists.GetByTitle("testlist");
SPCustomers printer = dataForm1.CurrentItem as SPCustomers;
ListItem items = customerList.GetItemById(printer.id);
items["Title"] = printer.IPAddress;
items["make"] = printer.Make;
items["model"] = printer.Model;
items["x"] = printer.xCord;
items["y"] = printer.yCord;
items.Update();
context.ExecuteQueryAsync(OnRequestSucceeded, OnRequestFailed);
}
}
}
private void dataForm1_AddingNewItem(object sender, DataFormAddingNewItemEventArgs e)
{
customerList = context.Web.Lists.GetByTitle("testlist");
SPCustomers printe = dataForm1.CurrentItem as SPCustomers;
ListItemCreationInformation itemcreationinfo = new ListItemCreationInformation();
ListItem items = customerList.AddItem(itemcreationinfo);
items["Title"] = printe.IPAddress;
items["make"] = printe.Make;
items["model"] = printe.Model;
items["x"] = printe.xCord;
items["y"] = printe.yCord;
items.Update();
context.ExecuteQueryAsync(OnRequestSucceeded, OnRequestFailed);
}
private void dataForm1_DeletingItem(object sender, System.ComponentModel.CancelEventArgs e)
{
SPCustomers printer = dataForm1.CurrentItem as SPCustomers;
ListItem oListItem = customerList.GetItemById(printer.id);
oListItem.DeleteObject();
context.ExecuteQueryAsync(OnRequestSucceeded, OnRequestFailed);
}
}
}
and my dataform:
<df:DataForm ItemsSource="{Binding}" Height="276" HorizontalAlignment="Left" Margin="12,12,0,0" Name="dataForm1" VerticalAlignment="Top" Width="376" EditEnded="dataForm1_EditEnded" AddingNewItem="dataForm1_AddingNewItem" DeletingItem="dataForm1_DeletingItem" CommandButtonsVisibility="All" />
Thanks for the help.
update: changed to this will answer in like 7 hours when it lets me

Answer 1

never mind I figured it out I changed my editended to this and deleted my addingNewitem method entirely. Now I just have to hide the ID field and it will be working perfectly
private void dataForm1_EditEnded(object sender, DataFormEditEndedEventArgs e)
{
if (e.EditAction == DataFormEditAction.Commit)
{
customerList = context.Web.Lists.GetByTitle("testlist");
SPCustomers printer = dataForm1.CurrentItem as SPCustomers;
ListItem items;
if (printer.id != 0)
{
items = customerList.GetItemById(printer.id);
}
else
{
ListItemCreationInformation itemcreationinfo = new ListItemCreationInformation();
items = customerList.AddItem(itemcreationinfo);
}
items["Title"] = printer.IPAddress;
items["make"] = printer.Make;
items["model"] = printer.Model;
items["x"] = printer.xCord;
items["y"] = printer.yCord;
items.Update();
context.ExecuteQueryAsync(OnRequestSucceeded, OnRequestFailed);
}
}
