Silverlight Datagrid - Retrieving details on Editing

In this article we would be seeing how we are going to retrieve the details on Editing the DataGrid or Listbox.

Created a new Project SLDatagridClick and

Add a DataModel as shown below to the Web Project.





Data Model is created as shown below :




Add a method to the DataService as shown below :

[OperationContract]
public IEnumerable GetPersons()
  {
  DataEntities context = new DataEntities();
 
  var persons = from o in context.People
  select new Persons
  {
  id = o.ID,
  firstName = o.FirstName,
  lastName = o.LastName
  };  
  return persons;
  }
 
public class Persons
  {
  public int id { get; set; }
  public string firstName { get; set; }
  public string lastName { get; set; }
  }

Add the Service Reference to the Silverlight Project.



Now lets get into the Silverlight project.

Modify the MainPage.xaml.cs as shown below :

using SLDatagridClick.DataServiceReference;
 
namespace SLDatagridClick
{
  public partial class MainPage : UserControl
  {
  public MainPage()
  {
  InitializeComponent();
  DataServiceClient client = new DataServiceClient();
  client.GetPersonsCompleted += new EventHandler(client_GetPersonsCompleted);
  client.GetPersonsAsync();
  }
 
  void client_GetPersonsCompleted(object sender, GetPersonsCompletedEventArgs e)
  {
  dg.ItemsSource = e.Result;
  }
  }
}

Now lets give it a run and see the output :



Now lets get to work. When I Edit the cell , I should be able to retrieve the modified cell contents. I have just tried to bring together some of the scenarios I came across while using Datagrid. In this article I would demonstrate one such scenario :

Lets add the code for that scenario :

Add the event handler :

dg.CellEditEnded += new EventHandler(dg_CellEditEnded);

Make use of the CellEditEnded.
