        image

    • [Fix] Issue where Hour 0 is not shown when using 24h clock

  • New AutoWatermark attached property at TextBoxHelper #2722 (@xxMUROxx) which is able to get the DisplayAttribute from the bound property in following cases:
    • Binding that is supported
      • "{Binding Path=Property}"
      • "{Binding Path=Property.SubProperty}"
      • "{Binding Path=CollectionProperty}"
      • "{Binding Path=CollectionProperty[0].SubProperty}"
    • Binding that is not supported
      • "{Binding Path=CollectionProperty[0]}"

      • HorizontalContentAlignment="Stretch" and Position="Right" Flyout which covers the whole window

    • Default close button action (no closing event yet)
  • TextBox ContextMenu changes #2772, #2758 by @Deadpikle
    • If you want to use the default context menu items cut, copy and paste you must do nothing
    • If you want to use your own context menu items without the default items you must do this ```xaml
      + If you want to use your own context menu items with the spell checker items then you must do this
      ```xaml
      <TextBox Margin="{StaticResource ControlMargin}"
              Controls:TextBoxHelper.IsSpellCheckContextMenuEnabled="True"
              Text="Enabled">
          <TextBox.ContextMenu>
              <ContextMenu>
                  <MenuItem Header="This is only a Test-Item" />
              </ContextMenu>
          </TextBox.ContextMenu>
      </TextBox>
    
    • If you want to use your own context menu items with the deafult items then you must do this ```xaml

    ```

  • CustomDialog improvements #2775
    • New overloaded generic method ShowMetroDialogAsync to create and show custom dialogs (self created dialogs which are inherited from CustomDialog) ```csharp // create and show a new custom dialog of the given type with the default dialog settings var customBaseMetroDialog = await this.ShowMetroDialogAsync();

    // create and show a new custom dialog of the given type with own settings var customBaseMetroDialog = await this.ShowMetroDialogAsync(this.metroDialogSettings);

      + Better handling for dialogs settings also with the already available `ShowMetroDialogAsync` method
      ```csharp
      // create and show custom dialog with default settings
      await this.ShowMetroDialogAsync(new CustomBaseMetroDialog());
    
      // create and show custom dialog with own settings
      await this.ShowMetroDialogAsync(new CustomBaseMetroDialog(this.metroDialogSettings));
      // or
      await this.ShowMetroDialogAsync(new CustomBaseMetroDialog(this, this.metroDialogSettings));
    
    • It’s now also possible to configure the dialog settings at the custom dialogs class itself.
        protected override MetroDialogSettings ConfigureSettings(MetroDialogSettings settings)
        {
        return new MyCustomDialogSettings();
        }
      
    • Here is the source for the given samples ```xaml
    
      ```csharp
      namespace ShowMetroDialogAsyncIssue
      {
          using System.Windows;
          using MahApps.Metro.Controls;
          using MahApps.Metro.Controls.Dialogs;
    
          public partial class CustomBaseMetroDialog : CustomDialog
          {
              public CustomBaseMetroDialog()
              {
                  InitializeComponent();
              }
    
              public CustomBaseMetroDialog(MetroDialogSettings settings) : base(settings)
              {
                  InitializeComponent();
              }
    
              public CustomBaseMetroDialog(MetroWindow parentWindow, MetroDialogSettings settings) : base(parentWindow, settings)
              {
                  InitializeComponent();
              }
    
              private void Close_OnClick(object sender, RoutedEventArgs e)
              {
                  (this.OwningWindow ?? (MetroWindow)Application.Current.MainWindow).HideMetroDialogAsync(this);
              }
          }
      }

Version 1.0.0 released

Notes

This is the first stable release of MahApps.Metro.

We removed everything marked as obsolete and made some API changes, but from now on MahApps.Metro follows Semantic Versioning, at least API wise. Please note that minor visual changes can still occur if there’s a need for them.

A migration guide for the breaking changes is available here: https://github.com/MahApps/MahApps.Metro/blob/master/docs/v1.0-Migration-Guide.md

Features

  • Added a StatusBar and StatusBarItem style #1558
  • Added the TitleVisibility and CloseButtonVisibility properties to the flyouts to control the visibility of the header.
  • Added the ButtonHelper.PreserveTextCase attached property to control the automatic upper and lower casing of certain buttons. #1622
  • If an .ico file contains multiple icon sizes, MetroWindow now automatically selects the optimal icon size. #1242 #1628
  • ShowMetroDialogAsync now accepts MetroDialogSettings as argument so custom dialogs derived from the CustomDialog class can have a fade-in and fade-out animation
  • The ToggleSwitch control can now be dragged with the mouse to change the enabled state #1652 #1595
  • The CleanWindow’s close button now has a red background when hovering with the mouse.

Changes

  • The IsOpenChangedEvent of the Flyout control is now a routed event
  • The animation of the Flyout control matches the Windows 8 flyout behavior more closely #1460
  • Changed the event names of the ‘NumericUpDown’ control control #1518
  • Split up the ControlsHelper class into multiple more granular helper classes #1520 #1582
  • SimpleDialog has been renamed to CustomDialog #1613
  • BaseMetroDialog now inherits from ContentControl instead of Control. The DialogBody property has effectively been replaced by the Content property. #1615
  • All elements in the titlebar now use the IdealForegroundBrush for a better contrast to the accent color. #1611
  • The text in dialog buttons isn’t lowercase by default anymore.
  • Eliminated the need to pass the owning BaseMetroTabControl to MetroTabItem #1624
  • TextBoxHelper is now written with an uppercase B to match TextBox.

Bugfixes

  • Fixed the TabItem close button requiring MahApps.Metro.Resources #1524
  • Fixed the ClearType partially not working #1537
  • Fixed flyouts closing when clicking on a formatting element #1487 #1508

  • Fixed the ToggleSwitch control not respecting the height and width properties. #1652 #1466
  • Fixed MetroProgressBar System.Windows.Media.Animation Warning 6 #1664
  • Fixed opening animation of dynamically created flyouts #1665 #1655
  • Fixed WindowSettings SaveWindowPosition saves to position 0,0 if window not shown #1671 #1672
  • Fixed memory leak and exception with dynamically created Flyouts (mostly happens with Caliburn) #1681
  • Fixed the focus border not showing up for message dialog buttons #1679 #1684
  • Fixed the automatic focus for dialogs #1679 #1684
  • Fixed blurry contextmenu/menu and menu items #1674 #1685

Version 0.14.0 released

Notes

We’re nearly ready to release version 1.0 of MahApps.Metro, so this may be the last unstable release.

There are no known breaking changes in this release, but we had to deprecate some things, particularly around the titlebar overlay behavior.

Please note that everything that is know deprecated will be removed in the 1.0 release, so you should prepare your applications soon.

Since we’re following semantic versioning, we promise to not break anything from version 1.0 to 2.0.

Features

MetroWindow now indicates whether it’s active or not

The MetroWindow now has the NonActiveWindowTitleBrush property that sets the window brush for an inactive window.

See PR #1320

Fine grained control over the titlebar element overlay behavior

The overlay behavior of the elements of the window titlebar can now be controlled individually.

There are is now an enum with four values:

  • Never
  • OverlayFlyout
  • OverlayHiddenTitleBar
  • Always

For more info, see PR #1427.

Underlined TabControl

Added the attached property ControlsHelper.IsUnderlined="True" for the TabControl control that adds an underline.

See PR #1425 for reference.

Custom ScrollBar width and height

The default ScrollBar width and height can now be set manually.

See PR #1387for more infos.

Version 0.13.0 released

Notes

The 0.13 release of MahApps.Metro marks a very important change in the MetroWindow infrastructure along with several other fixes and improvements.

We’ve also updated the MahApps.Metro.Resources NuGet package with the latest icons.

Features

Custom themes

MahApps.Metro now allows to define custom themes for the application. We’ve rewritten the ThemeManager for this (don’t worry, your old code should still work, but most old methods are now marked as Obsolete)

To add a theme, use the new AddAppTheme theme method.

Completely rewritten BorderlessWindowBehavior

The BorderlessWindowBehavior has been completely rewritten, to fix a number of issues that have accumulated over time.

For a complete list of fixes, see PR #1156

Auto-closing flyouts

Flyouts now have an option to be automatically closed when the user clicks outside of the flyout. We renamed the property IsPinnable (that had no use) to IsPinned for this. IsPinned is true by default and, if set to false, enables the auto-closing feature.

RangeSlider

The RangeSlider control has been completely rewritten because it was unusably broken before.

See PR #1055 for more info.

Titlebar enhancements

  • The titlebar now supports vector icons

New website URL

From now on, the Mahapps.Metro documentation site lives at http://mahapps.com, instead of http://mahapps.com/MahApps.Metro

This means less typing for everyone!

The old links should still work and redirect to the top level domain.

Version 0.12.1 released

Notes

This is a bugfix release. It will most likely be the only bugfix release till v0.13.

Fixes

  • Fixed various bugs with the themed Flyouts (#947 #949):
    • A dark Flyout doesn’t have dark window commands anymore
    • Only the topmost Flyout changes the WindowCommands, if it is closed, the WindowCommands adapt to the underlying Flyout
    • Theme changes are respected properly
  • Flyouts respect the template margin #867 #974
  • Fixed an OverflowException in the CleanWindowStyle #897 #903
  • Fixed various bugs for the NumericUpDown control: #952 #953
    • Fix for NumericUpDown exception raised when trying to enter a number in scientific notation
    • Fixed a problem with too early speedup
  • Improved the performance for theme changes, they should now work instantly.
  • Fixed an issue with the WindowCommands of a CleanWindow, they were white and therefore invisible when a BorderlessWindowBehavior was attached.

Version 0.12.0 released

Notes

After only 2 months and nearly 300 commits, this is one of the feature-richest releases we’ve ever done.

This release, again, contains some breaking changes. We try to break things now rather than later, when we release version 1.0 (which is hopefully soon).

A quick overview:

  • ProgressIndicator is now removed, as it wasn’t working as expected. Use MetroProgressBar with IsIndeterminate = True instead, which should give a much smoother experience.
  • Like ProgressIndicator, MetroImage has been removed because it was broken. A better alternative is to use a simple Rectangle, as described here
  • For the same reasons, the Panorama control has been removed. While we have no drop-in replacement for this control, if you really want it back, you can always submit a pull request with a better Panorama, but beware, it most likely needs a serious rewrite.

Upcoming changes:

  • The RangeSlider control is currently being rewritten, so expect some breaking changes here.

Features

Dialog system

The dialog system has been overhauled for better extensibility.

The SimpleDialog class now allows to create a custom dialog.

ProgressDialog is a dialog that displays progress (duh!) inspired by Github for Windows. InputDialog works like the MessageDialog but allows the user to input text.

For reference, see PR #785 , #860 and #901 .

Just like modal dialogs, Flyouts can now be made modal by setting the IsModal = true. Thanks @grokys for this feature!

For reference, see PR #824

Themed Flyouts

A Flyout can now have a theme, just like MetroWindow

There are four different theme states, indicated by the FlyoutTheme enum:

  • FlyoutTheme.Adapt: The flyout will use the theme if the host window
  • FlyoutTheme.Inverse: The flyout will use the inverse theme of the host window
  • FlyoutTheme.Dark: Always dark. This is the default value
  • FlyoutTheme.Light: Always use the light theme
  • FlyoutTheme.Accent: Instead of the dark/light theme, use the accent of the host window

This behavior can be set through the Theme property

For reference, see PR #941

Expander

Added new Expander control that can can be used to close/open for example a GroupBox Thanks @Icehunter for this feature!

For reference, see PR #834

NumericUpDown

Implemented a NumericUpDown control, inspired by the Callisto style. Thanks @xxMUROxx for this feature!

New icons

Two new icons have been added to Mahapps.Metro.Resources:

  • appbar_more_horizontal
  • appbar_more_vertical

For reference, see PR #887

MetroNavigationWindow

Implemented a MetroNavigationWindow. This is the re-implementation of System.Windows.Navigation.NavigationWindow in a Metro-style

For reference, see PR #801

ContentTemplateSelector support for TransitioningContentControl.

You can now provide a ContentTemplateSelector for the TransitioningContentControl.

Added AccentedSquareButton and IdealForegroundColor key

  • Added an AccentedSquareButton. It looks like the SquareButton except that its Background is the current Accent.
  • Added an IdealForegroundColor key to every accent.

Changes

  • Removed title parameter from ShowMetroDialogAsync #842

For reference, see PR #846

Fixes

  • Fixed high GPU usage when the MetroProgressbar is hidden. #812 #817

  • Fixed the ToggleSwitch’s built-in Top/Left margin #878 #880
  • Fixed ThemeManager’s OnThemeChanged work-around conflicting with other WPF internals #923 #932

Version 0.11.0 released

Notes

Warning: This release has a few breaking changes. A quick overview:

  • ‘Colours’ -> ‘Colors’ For consistency, we’ve chosen to rename all occurendes of ‘Colours’ to ‘Colors’
  • The ‘TransitioningContentControl’ use now an enumeration for ‘Transition’

More details here: https://github.com/MahApps/MahApps.Metro/wiki/Breaking-Changes-or-WTF-is-happening-with-the-ALPHA-version

Other things:

  • You can now put all the resource dictionaries in your ‘App.xaml’ file
  • ProgressIndicator is marked as ‘Obsolete’. In future, use ‘MetroProgressbar’ with ‘Indeterminate’ set to ‘true’
  • Like the ProgressIndicator, the Panorama will be removed in future versions. There is a chance that it will be rewritten and reintroduced later on.
  • TextBox, PasswordBox, ComboBox and DatePicker use now the Validation.ErrorTemplate for displaying errors. The default template is ValidationErrorTemplate.
  • The Demo application has been completely rewritten.
