The height of the application window in pixels. The default is the WindowSettings.Height setting in the application manifest.

ArgumentOutOfRangeException

The specified value when setting this property is greater than the available screen height.

You can set this property only in the following cases:

The minimum window height is dictated by the operating system. If you set this property to a value below this minimum, the value is ignored.

The following code example demonstrates the use of this property. In this example, the window position and dimensions were previously saved to the ApplicationSettings in the isolated storage as a user defined key/value pair. These key/value pairs are retrieved and used to set the current value of the window settings.


Private Sub Application_Startup(ByVal o As Object, ByVal e As StartupEventArgs) Handles Me.Startup
    Me.RootVisual = New MainPage()

    ' Set the window position and dimensions to the previoius settings.
    ' The key/value pairs in the ApplicationSettings are user defined.
    If (Application.Current.IsRunningOutOfBrowser) Then

        ' Get the application settings from IsolatedStorage.
        Dim appSettings As IsolatedStorageSettings = IsolatedStorageSettings.ApplicationSettings

        ' Get a reference to the main window.
        Dim mainWindow = Application.Current.MainWindow

        ' Set the Window.Top property.
        If (appSettings.Contains("WindowTop")) Then
            mainWindow.Top = Convert.ToDouble(appSettings("WindowTop"))
        End If

        ' Set the Window.Left property.
        If (appSettings.Contains("WindowLeft")) Then
            mainWindow.Left = Convert.ToDouble(appSettings("WindowLeft"))
        End If

        ' Set the Window.Width property.
        If (appSettings.Contains("WindowWidth")) Then
            mainWindow.Width = Convert.ToDouble(appSettings("WindowWidth"))
        End If

        ' Set the Window.Height property.
        If (appSettings.Contains("WindowHeight")) Then
            mainWindow.Height = Convert.ToDouble(appSettings("WindowHeight"))
        End If
    End If
End Sub
