We take a Silverlight application and write the following XAML code in editor

<Grid x:Name="LayoutRoot" Background="White">
<ComboBox Height="42" HorizontalAlignment="Left" ItemsSource="{Binding }" Margin="38,35,0,0" Name="ComboBox1" VerticalAlignment="Top" Width="134" Background="#FF365772" Foreground="#FF3D3F41" />
</
Grid>

We write the following code on MainPage.xaml.vb

Partial Public Class MainPage
Inherits UserControl
Public Sub New()
InitializeComponent()
Dim ss As String() = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday","Saturday"}
Me.DataContext = ss
End
Sub

End
Class

Then, we run our application. When we Click on ComboBox, all the items are displayed in it and we can simply select one of them. Like below figure
