Gets or sets the main application UI.
(in System.Windows.dll)
Visual Basic (Declaration)
Public Property RootVisual As UIElement
Get
Set
Dim instance As Application
Dim value As UIElement
value = instance.RootVisual
instance.RootVisual = value
public UIElement RootVisual { get; set; }
You can set the value of the RootVisual property only one time from code, although you get its value any number of times.
The following code example demonstrates how an application can use a Startup event handler to set the RootVisual property.
Partial Public Class App
Inherits Application
public Sub New()
InitializeComponent()
End Sub
Private Sub Application_Startup(ByVal o As Object, _
ByVal e As StartupEventArgs) Handles Me.Startup
Me.RootVisual = New Page()
End Sub
End Class
using System.Windows; // Application, StartupEventArgs
namespace SilverlightApplication
{
public partial class App : Application
{
public App()
{
InitializeComponent();
}
private void Application_Startup(object sender, StartupEventArgs e)
{
// Specify the main application UI
this.RootVisual = new Page();
}
}
}
