Using in-memory Data

The purpose of this tutorial is to show you how to populate a RadGridView with in-memory data.

The control will be bound to an ObservableCollection of Car objects. Each Car has a Name and Description.

  • Create a new class named Car and add two properties - Name and Description. Both of the properties are of type string. Here is the source code:

public class Car 
{ 
    public Car() 
    { 
    } 
 
    public Car(string name, string description) 
    { 
        this.Name = name; 
        this.Description = description; 
    } 
 
    public string Name 
    { 
        get; 
        set; 
    } 
 
    public string Description 
    { 
        get; 
        set; 
    } 
} 
Public Class Car 
 
    Public Sub New() 
    End Sub 
 
    Public Sub New(ByVal name As String, ByVal description As String) 
        Me.Name = name 
        Me.Description = description 
    End Sub 
 
    Private _Name As String 
    Public Property Name() As String 
        Get 
            Return _Name 
        End Get 
        Set(ByVal value As String) 
            _Name = value 
        End Set 
    End Property 
 
    Private _Description As String 
    Public Property Description() As String 
        Get 
            Return _Description 
        End Get 
        Set(ByVal value As String) 
            _Description = value 
        End Set 
    End Property 
End Class 
  • Create a new class named RadGridViewSampleData.

public class RadGridViewSampleData 
{ 
    public RadGridViewSampleData() 
    { 
        Cars = new ObservableCollection<Car>(); 
        Cars.Add(new Car("BMW", "A german luxury car.")); 
        Cars.Add(new Car("Porsche", "A german sports car.")); 
        Cars.Add(new Car("Citroen", "A french luxury car.")); 
        Cars.Add(new Car("Renault", "A french family car.")); 
    } 
 
    public ObservableCollection<Car> Cars 
    { 
        get; 
        set; 
    } 
} 
Public Class RadGridViewSampleData 
    Public Sub New() 
        Cars = New ObservableCollection(Of Car)() 
        Cars.Add(New Car("BMW", "A german luxury car.")) 
        Cars.Add(New Car("Porsche", "A german sports car.")) 
        Cars.Add(New Car("Citroen", "A french luxury car.")) 
        Cars.Add(New Car("Renault", "A french family car.")) 
    End Sub 
 
    Private _Cars As ObservableCollection(Of Car) 
    Public Property Cars() As ObservableCollection(Of Car) 
        Get 
            Return _Cars 
        End Get 
        Set(ByVal value As ObservableCollection(Of Car)) 
            _Cars = value 
        End Set 
    End Property 
End Class 
  • Declare the RadGridViewSampleData object as a resource in your application.

<Grid.Resources> 
    <my:RadGridViewSampleData x:Key="DataSource"/> 
</Grid.Resources> 
  • Update your RadGridView declaration - set the ItemsSource property.

<telerik:RadGridView x:Name="radGridView" ItemsSource="{Binding Source={StaticResource DataSource}, Path=Cars}"/> 
Run your demo, the result can be seen on the next picture:

If you need to define the columns manually read the topic Defining Columns.
