Gets the size and location of a window before being either minimized or maximized.
Assembly: PresentationFramework (in PresentationFramework.dll)
The restore rectangle is the region occupied by the window before it was minimized or maximized. You can use to save the last size and location of a window before an application is closed, and retrieve those values the next time an application starts to restore a window to the way a user left it.
If you query before the window has been shown or after it has been closed, Empty is returned.
You cannot get this property when a window is hosted in a browser.
The following example uses and isolated storage to ensure the size and location of a window are the same as they were the previous time the window was shown.

Partial Public Class MainWindow Inherits Window Private filename As String = "settings.txt" Public Sub New() InitializeComponent() ' Refresh restore bounds from previous window opening Dim storage As IsolatedStorageFile = IsolatedStorageFile.GetUserStoreForAssembly() Try Using stream As New IsolatedStorageFileStream(Me.filename, FileMode.Open, storage) Using reader As New StreamReader(stream) ' Read restore bounds value from file Dim restoreBounds As Rect = Rect.Parse(reader.ReadLine()) Me.Left = restoreBounds.Left Me.Top = restoreBounds.Top Me.Width = restoreBounds.Width Me.Height = restoreBounds.Height End Using End Using Catch ex As FileNotFoundException ' Handle when file is not found in isolated storage, which is when: ' * This is first application session ' * The file has been deleted End Try End Sub Private Sub MainWindow_Closing(ByVal sender As Object, ByVal e As CancelEventArgs) ' Save restore bounds for the next time this window is opened Dim storage As IsolatedStorageFile = IsolatedStorageFile.GetUserStoreForAssembly() Using stream As New IsolatedStorageFileStream(Me.filename, FileMode.Create, storage) Using writer As New StreamWriter(stream) ' Write restore bounds value to file writer.WriteLine(Me.RestoreBounds.ToString()) End Using End Using End Sub End Class
