Silverlight Datagrid - Retrieving details on Editing

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<Persons> 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<GetPersonsCompletedEventArgs>(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<DataGridCellEditEndedEventArgs>(dg_CellEditEnded);

Make use of the CellEditEnded.
