If you done every thing correctly, the below line would be binding statement for c#.
this.dataGrid1.ItemsSource = _OrganizationContext.Employees
and for VB.NET is :
Me.dataGrid1.ItemsSource = _OrganizationContext.Employees
They both are located in coding block in 16th step.
* Do not forget to initialize it
* If you don't get the data that you see on the sample, review your code starting from step 7th
* some people might have a little problem with Step 11 & Step 12, if they do not understand XAML. Make sure that you do these steps correctly.
* Make sure you have some data in your database
The execution flow of the code in step 16:
-> First, it initializes the context (this is probably the one that you are looking for
OrganizationContext _OrganizationContext = new OrganizationContext();
-> In Constructure, it initializes the Silverlight Components (things that defined in XMAL)
InitializeComponent();
-> Bind the data grid on UI with the context
this.dataGrid1.ItemsSource = _OrganizationContext.Employees
-> Load data to context Object
_OrganizationContext.Load(_OrganizationContext.GetEmployeesQuery());
Since ItemsSource of dataGrid1 references to Employees Property of OrganizationContext. So when you do _OrganizationContext.Load you data is updated and so should your view.
If this still does not work, try
_OrganizationContext.Load(_OrganizationContext.GetEmployeesQuery());
this.dataGrid1.ItemsSource = _OrganizationContext.Employees;
