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}"/>
If you need to define the columns manually read the topic Defining Columns.
