This version includes new controls, new WindowChrome features for Windows 11, many improvements for SyntaxEditor and its add-ons, updates to nearly all WPF products, and now includes .NET 5 assemblies in the NuGet packages with validated .NET 6 compatibility.
Added a rich API that can create modern, themed dialogs for anything from simple messages and confirmations, to more advanced scenarios like exception notification dialogs or file copy dialogs.
We even include a ThemedMessageBox object with static methods that match the native WPF MessageBox API. Our themed version of the MessageBox uses a chromed WPF Window instead of Win32 dialogs (as the default WPF MessageBox does), along with fluent icons. This is important when your app is in a dark theme because it allows all message/confirmation dialogs to match the theme. You can instantly modernize all message box display in your app to our implementation with a single line of code too.
Added a new control that is often seen as a replacement for a traditional CheckBox in modern user interfaces.
It's easy to customize the appearance of ToggleSwitch to support other styles as well.
Made numerous updates to PopupButton to improve focus handling, tooltip display, key handling, and knowing when to close itself.
WindowChrome Windows 11 Support
WindowChrome has added support for Windows 11 where it will use rounded corners and system-rendered drop shadows. In addition, hovering over the title bar's Maximize or Restore buttons will show the Windows 11 Snap Layout menu.
A new sample demonstrates synchronizing the scroller and splitter of one editor instance with another.
Drag and Drop
Improved drag/drop interaction and related scrolling in several scenarios, and add a new Drag and Drop QuickStart sample.
Single-Line Mode QuickStart
Added a formula example with alternate style for nested parentheses.
Editing and Caret Movement
Made many small improvements in the areas of editing and caret movement, especially in certain special contexts.
Improved popups to reposition themselves as the editor is scrolled.
The vertical scrollbar has been updated to handle collapsed regions more smoothly.
SyntaxEditor .NET Languages Add-on
Updated to support C# 8.0 syntax.
Go To Definition QuickStart
A new sample that demonstrates using an IResolver to navigate to the source of a reference.
The outliner will now create nodes for code-level constructs such as block statements by default.
SyntaxEditor Web Languages Add-on
Updated to support ECMAScript 2021 (12 Edition) syntax.
JSON Syntax Language
SyntaxEditor Python Language Add-on
Updated to support Python v3.9.5 syntax.
Updated to support namespace packages.
Added a FilterApplied event that is raised after the current filtering state has been applied to all of the control's items, generally occurring when DataFilter is changed, or filtering is enabled or disabled
Added a new item adapter method that can improve performance in large trees when searching for a tree node, and improved focus tracking and filtering.
Commit Trigger Changes
Updated edit box commit triggers so that commit on focus loss is now optional.
Improved Cultural Support
Updated the numeric edit boxes to support input of Full-width and Arabic-Indic digits.
Charts and Micro Charts
New Aggregation Kinds
Added SignedMaximum and SignedMinimum aggregation options that compare against absolute values while retaining the sign of the original value; e.g., -5 is greater than 4.
We are pleased to announce the release of the 2020.1 version of our WPF Controls, which is the culmination of many months of work to modernize themes across all Actipro and native WPF controls, create a unique and powerful framework to fully customize theming in your apps, and build a Theme Designer application for configuring/previewing theme definitions.
In addition to those features, we’ve added new controls, implemented a new Sample Browser application design, provided .NET Core assemblies and NuGet packages, and created a new product installer.
Let’s take a look at a handful of the larger updates.
Updated to Office 2019 Style
We have gone through every Ribbon-related control and made style improvements to match the latest appearance found in Office 2019.
We also wanted to provide fluid animations throughout the Ribbon, similar to Office. When you move your mouse over a tab, the underline animates to fill the tab. When you select a new tab, the tab’s content animates into place with a quick slide.
The Ribbon Backstage takes advantage of our new WindowChrome overlays mechanism and is now fully animated on display as well.
The Actipro WPF controls provide numerous complete pre-defined themes that render similar to various Windows and Office versions. These themes apply to Actipro and optionally native WPF controls as well so that there is consistency throughout your application’s appearance. While this system has always worked well, the old pre-defined themes were somewhat difficult to customize. We wanted to take themes to the next level for the new version, and we have truly built something fantastic.
Theme Definitions and Generation
v2020.1 has a new framework where you can configure numerous options on a theme definition object. When you register that theme definition with our ThemeManager, you then can apply that theme at any time with a single line of code. Multiple theme definitions can be registered, allowing you to register “light” and “dark” themes (or any other variant you like) and instantly toggle between them at run-time.
There are well over 50 theme definition options so far, including options for color palette, border contrast, bullet appearance, font size, corner radius, window appearance, and much more.
Like one of our pre-defined themes but wish to enable rounded corners on controls instead of square corners? A few lines of code can accomplish this. Want to build out your own custom color scheme for your app? No problem! The theme generator will construct over 1,000 resources like Brushes, Thicknesses, etc. that can be reused anywhere in XAML, and all based on your theme definition’s options.
Theme Designer Application
A very important piece of theming is being able to visualize exactly how altering theme definition options affects the rendering of various controls. That’s where the new Theme Designer application comes into play.
The Theme Designer application provides numerous "entire-theme preset" menu items that initialize a theme definition based on one of our pre-defined themes:
Here you see the app using the selected theme preset with some sample List/Grid UI in the document area. The Code document lists App.OnStartup code that you can paste into your own application to replicate the same theme in your application.
The Theme Definition tool window on the right contains a property grid where you can fully customize the many theme definition options. When a theme definition option is changed, the Code document’s text is updated appropriately to set non-default values, and the app itself immediate applies the theme so you get instant feedback on how theme definition options affect the appearance.
Color palettes can be configured to fit your brand, such as here where we have created a dark theme with heavy blue tint.
A resource browser tab lets you copy a DynamicResource to any of the resources generated from the theme definition. And many tabs containing sample user interface controls are included, allowing you to fully visualize how the theme will look with real-world controls.
This new Theme Designer application will be a key addition moving forward for our WPF Controls customers.
All Styles/Templates Updated
We’ve refactored all our Actipro and native WPF control styles/templates to take on a more modern appearance. In modern themes, glyphs now use more of a chevron appearance, there are updated scrollbar visuals, and there are soft downward drop-shadows. We’ve added all this, and a lot more. As mentioned above, everything can be configured in theme definitions to look exactly how you want.
High-Contrast Theme Improvements
We’ve reworked the entire high-contrast theme so that all UI in Actipro and native WPF controls renders well in high-contrast mode, ensuring your app is fully-accessible to all customers.
We’ve built optional features into ThemeManager that can automatically track the Windows light/dark setting for apps, and detect when high contrast mode is activated. When any of those options change, ThemeManager can automatically change your app theme appropriately to a theme you selected for each of those scenarios.
WindowChrome, which is included in the Shared Library, allows any WPF Window to have advanced chrome features. In the past this has mostly related solely to providing a themed window that had a Metro, Office, or Aero-like appearance. Version 2020.1 adds an extensive set of new features that customers are going to love.
A new MVVM-compatible overlay feature allows custom content to be injected that overlays the entire window, including the title bar area. This feature supports several built-in animations and offers up all kinds of exciting possibilities for your apps.
Anything from an Office-like home screen to a processing indicator can be implemented in the overlay.
Title Bar Customization
Title bars can be customized to include any custom content on the left side, center, or right side of the title bar. Each one of those areas is treated like a ContentControl so that they can be configured via child controls directly, or via MVVM models and DataTemplates.
It’s now easy to add a Menu into the title bar, as seen in many modern apps.
You can replace the title bar icon with a Back button.
Or add a user profile button on the right side of the title bar.
The central header portion of the title bar can even be replaced with custom content, like a popup button.
Title Bar Merge
Some modern apps have a more stylized design for their windows and don’t wish to have a traditional window title bar appearance. This is often achieved by merging portions of the window’s content into the title bar area. New WindowChrome features offer three kinds of merge options.
A merge kind of BackgroundOnly moves the Window.Background fill to cover the title bar background, while keeping the actual Window.Content in its normal location. A merge kind of ContentOnly keeps the Window.Background fill where it normally is, but moves the Window.Content to extend over the title bar background. Finally, a merge kind of Full moves both the Window.Background and Window.Content to extend over the title bar background.
System Menu Customization
WPF Windows have always used Win32 to provide their system menus, which are menus displayed when clicking the window’s title bar icon, or when right-clicking on the window title bar. The Win32 system menu is not rendered by WPF, and therefore never matches the style of a WPF application. This is especially evident when using dark themes in your app.
WindowChrome updates automatically replace the Win32-based system title bar context menu with a custom WPF-based one with similar functionality that renders the same as other menus in your app. This means it will look great in dark theme. Further, the menu can be fully customized, allowing additional menu items to be injected prior to display.
Image adaptation is a new feature area that is a real game changer in many applications. Combined with our DynamicImage control, image adaptation consists of a number of ways to manipulate images for display in various scenarios like dark themes, high-DPI, and monochrome.
Chromatic adaptation (color shifting) for images, which allows images designed for light themes to be automatically adjusted for use in dark themes.
Converting a monochrome vector image to render in the current foreground color.
Dynamic loading of pre-defined high-DPI and/or theme-specific image variations for raster images.
Conversion of images to grayscale.
Conversion of images to monochrome, in a specified color.
Effectively, you can design a single set of icons for a light theme, and reuse those same icons in dark and high-contrast themes with almost no additional effort.
The PropertyModel class, which is intended for manually-created properties that should appear in a PropertyGrid, has been updated to be a dependency object so that it can support XAML bindings on its properties.
This feature combined with a new CanAutoConfigure option makes it easy to specify several properties in XAML that should be displayed in a PropertyGrid. You simply bind the PropertyModel.Value to a property on another object and it fills out the rest, including selection of a property editor. You can also override the automatic configuration as needed, such as when you want a specialized property label or editor.
The PopupButton had a lot of its internals and logic refactored and improved for more common use cases. New properties were added to make popup customization easier.
A new primitive ShadowChrome control has been added that renders modern drop shadows using optional shader effects.
It also can render beautiful downward shadow effects using high-performing WPF rendering procedures.
The MultiColumnPanel control can render child elements in multiple columns, collapsing columns down as available space decreases.
It's a space-efficient and visually-appealing way to render lists of items, or to break paragraphs of text up.
Fresh New Sample Browser Design
We completely reimagined the user interface of our WPF Controls samples application.
It now harnesses all of our themes improvements and provides a fast, efficient way to navigate and interact with our hundreds of samples.
.NET Core Assemblies
With v2020.1, our control products ship in both .NET Framework 4.0 and .NET Core 3.0 variations of assemblies. You will now be able to use native .NET Core-based Actipro assemblies in your .NET Core apps!
Another big request by customers has been for us to supply NuGet packages for our controls and we are delivering that in v2020.1. NuGet packages are published on nuget.org and contain both the .NET Core and .NET Framework variations of our assemblies.
We're happy to announce that the 2017.2 versions of our WPF, Universal Windows, and Silverlight controls have been released. These versions include some new controls, new features, and a lot of minor updates and bug fixes.
See all the details on the 2017.2 releases in the various announcement posts:
Full support for intra-line adornments is now included. These allow whitespace to be reserved above and/or below view lines, and adornments rendered in that space.
A first new sample shows implementation of a Visual Studio-like Code Lens adornment with info display and hyperlink.
A second sample shows a Visual Studio-like Peek Definition (embedded editor) display. This is accomplished using a second SyntaxEditor within an adornment of the outer SyntaxEditor.
Vertical scrolling logic has been refactored to better handle view lines of various sizes.
A couple new code outlining commands have been added: apply default outlining expansion and expand all outlining.
.NET Languages Add-on Roslyn Extensions
A new optional assembly is available that has Roslyn extensions for loading IBinaryAssembly instances that can be referenced by a project assembly, instead of using normal .NET reflection.
.NET Languages Add-on IntelliPrompt
IntelliPrompt completion is now available for object creation expression initializer member names.
A new property can be data-bound to your VM to float or restore a docking window. The default location request event allows for specifying that a docking window should open in a floating dock host. Docking windows that were closed while floating now support more precise restoration later. Dragging standalone floating docking windows by their tabs now has a better experience.
The read-only contextual indicator for documents now uses a separate display mechanism from the custom contextual indicators, allowing both to show at the same time.
A new AutoCompleteBox control has been added that allows text entry and provides suggestions for auto-completion.
This kind of control is ideal for use in search query and quick launch kinds of scenarios.
Clicking a date on the popup calendar now closes the popup.
The TreeListBox item adapter has been updated with a method that fires when hovering over an item during a drag, allowing you to determine whether it should be expanded.
New adapter methods have also been added that are called immediately before and after a drag, allowing for custom adornments to be displayed while dragging.
Shared Library (WPF/UWP)
A new AdvancedTextBlock control has been added that can show a tooltip when overflowed and can highlight spans of text based on captured text ranges (i.e. filter match results).
