Work on the WPF Controls 2020.1 version has begun. This version is going to have large updates to our themes system. Our goal is to focus on modern designs, allowing you to easily customize and personalize the themes used for your WPF applications. We have a lot of ideas that we're excited to work on and will be sharing over the coming months on the blog.
As we dive into this effort, we are removing old system themes that aren't really needed any more. For instance, "Classic" themes haven't been available as an option in Windows 10 for some time. "Luna" (Windows XP) themes are for an operating system that went end-of-life many years ago.
Similarly, Windows 7 is going end-of-life around the end of 2019 and Offce 2010 went mainstream end-of-life in 2015.
We are strongly considering dropping the Aero and Office 2010 themes so that we can slim down our product assemblies and focus on more current-era "modern" theming. Rest assured, what we have planned for modern themes will allow for a high degree of customization and ease-of-use.
We've created a Twitter poll so that you can share your thoughts on dropping Aero and Aero-like Office 2010 themes in our 2020.1 WPF Controls. We ask that you provide your opinion in this poll. If you would like to see them kept, please contact our support team with the reasons why.
Our v2019.1 WPF and Universal Windows controls have been updated with new maintenance releases that are now ready for download. There were a number of minor enhancements and bug fixes made across various products.
See the announcement posts for the detailed list of enhancements and updates:
The C# parser and resolver have been updated to support C# 7.3 syntax. Likewise, the VB parser and resolver have been updated to support VB 15.8 syntax. These enhancements allow SyntaxEditor's syntax checker and IntelliPrompt engine to work with recently-added C# and VB language features.
Triple-Click Selection
Triple-clicks now selects an entire view line. Dragging the pointer on the final click will extend the selection by view line.
Searching Improvements
Editor view searching and search result highlighting logic was improved, including offloading some pieces to worker tasks for better performance.
The search overlay pane's textbox now displays a red border when no match for the find text is located.
Shell (WPF)
Object Name Sorting
The name sort logic for shell objects now uses a natural sorting algorithm, where digits in the names are considered as numerical content rather than text. This behavior matches Windows' own sorting logic.
Grids
PropertyGrid DataObject Clearing
We added a new section to the PropertyGrid documentation that talks about best practices for clearing the DataObject property when the PropertyGrid is no longer needed to prevent memory leaks. We improved some of our own internal logic in how we watch for property value changes to help prevent memory leaks regardless. A PropertyGrid.CanClearDataObjectOnUnload property was also added that can be set to true to automatically clear the DataObject property when the control is unloaded.

VS 2019 Designer Functionality (UWP)
The original 2019.1 version of the UWP Controls changed the minimum Windows 10 target version to the Fall Creators Update. This change indirectly triggered a different set of designer functionality APIs in VS 2019 that are breaking changes from the old ones. This new UWP Controls maintenance release updates our designer functionality to be based on the newer APIs.
A new v2019.1 WPF controls maintenance release is now ready for download. This build makes numerous improvements and bug fixes across many products, with some more notable ones discussed below.
See the announcement post for the detailed list of improvements and updates.
All numeric edit boxes in Editors now allow you to specify the exact decimal place at which to round numeric values.
A DoubleEditBox that rounds to three digits
SyntaxEditor Touch Interaction
Touch-based input for operations such as scrolling, zooming, and selection have been greatly refined so that they are more natural.
IntelliPrompt Quick Info and Parameter Info
The previous build started supporting the use of syntax highlighting for foreground colors. A problem was that it was using some app resources for background colors, meaning some scenarios could occur where the foreground text would blend with the background.
The parameter info tip background now matches the view's background color
The fix for this problem made in this new build is to use the editor view's background color as the background of the quick info and parameter info tips. That ensures the foreground colors always render in a readable way in regards to the background.
A new v2019.1 WPF controls maintenance release is now ready for download. This build improves the new search overlay pane, updates how IntelliPrompt quick info and parameter info tips are rendered, and fixes several bugs.
See the announcement post for the detailed list of improvements and updates.
The search overlay pane will now automatically move the selection to the next match as the find text is typed.
Typing in the search overlay pane
In this example, we see how altering the find text causes the selection to instantly move to the next match.
IntelliPrompt Quick Info and Parameter Info
This build updates all IntelliPrompt quick info and parameter info tips to use syntax highlighting for foreground colors and new application-based theme brush resources for the background/border of the info tips themselves. Previously, info tips always rendered with a light background and generally used fixed colors for foregrounds.

This change was made to ensure that colors used in the info tips more closely resembles the actual syntax highlighting in SyntaxEditor. It also allows info tips in Metro Dark theme to use a dark background.
We are pleased to announce the release of the 2019.1 version of our WPF Controls. This version includes the massive SyntaxEditor enhancements and updates we’ve been working on that have previously been described as “SyntaxEditor vNext” in the blog.
Let’s dig in and see a handful of the larger SyntaxEditor updates.
Cross-Platform Design
The internals of SyntaxEditor have been heavily refactored to support a cross-platform API across the WPF, UWP, and WinForms platforms. This allows SyntaxEditor features for the three platforms to be kept in sync moving forward. The 2019.1 UWP and WinForms versions of SyntaxEditor will follow later this year.
Carets and Selection
Multiple Selections
Editing with multiple carets
Multiple selections, each with their own caret, are now supported. A new selection can be added by holding the Ctrl key when clicking in the text area or clicking on the selection or line number margins. Most edit actions have been refactored to fully support multiple selections. For instance, pressing Shift+Right Arrow will extend all of the selections by one character.
Typing and copy/paste with multiple selections
Copying text from multiple selections unions the selected text, joining each range's text with a line terminator. Pasting multi-line text into a view with the same number of selections as text lines being pasted will replace each selection with a related line from the pasted text.
Touch Selection Grippers
Selection grippers displayed for touch-based selection
Selection grippers will show for the primary selection when touch input is used.
Caret Movement
Carets now support movement at both the start and end of word wrapped lines.
The caret in virtual space past the end of a line
Virtual space is now supported at the end of lines when a new option is enabled. Block selections can be made in virtual space at the end of lines, even without line end virtual space being enabled. This prevents the caret from snapping to an offset when making a block selection, which can sometimes be problematic.
Search Overlay Pane
A new search overlay pane displays over the upper-right of the active editor view when Ctrl+F (find mode) or Ctrl+H (replace mode) are pressed in a multi-line editor. A toggle mode button on the search overlay pane switches between find and replace modes, and all common search options are supported via toggle buttons and other controls. The search overlay pane can be closed by clicking the X button or by pressing Esc.
Basic find and replace operations are available in the search overlay pane
Ctrl+F3 will open the search overlay pane without focusing it, and will search forward for the currently-selected text. Ctrl+Shift+F3 will do the same but will search backwards.
F3 will search for the next match of the previously-used search options. Shift+F3 will search for the previous match of the previously-used search options.
If the SyntaxEditor.IsSearchResultHighlightingEnabled property is true, the search results can be highlighted while the search overlay pane is open. Closing the search overlay pane, clears the search result highlights.
IntelliPrompt
Vector Images
All Metro images are vector-based and show crisply in high DPI
The Metro Light and Metro Dark common image sets are now in vector form and render beautifully in high DPI.
Completion Filters
Completion filter buttons can narrow down the items in the list, such as all .NET types
Completion filters have been updated so when there are multiple active filters with the same ICompletionFilter.GroupName, any one of those filters can includes an item. Toggle button completion filters were changed to appear unchecked when they aren't active, which is more natural.
Ctrl Key Opacity Changes
The logic for making IntelliPrompt popups and the new search overlay pane semi-transparent when the Ctrl key is held has been refactored and improved. A brief delay was added before the opacity change occurs.
Splitting
The scrollbar splitter button now has a larger appearance.
Splitting a view, and the new option to drag to the bottom to keep the top view
The view splitter can be dragged to the bottom of the view to remove the split and keep the top view.
Scrolling and Zooming
Touch Scrolling
Smooth inertia-based touch scrolling has been added.
Auto ScrollBar Visibility
In Auto mode, the horizontal scrollbar is hidden since no horizontal scrolling is possible
The horizontal and vertical scrollbars now support an Auto visibility option that will only display then when necessary.
Horizontal Scrolling
Editor views can be scrolled horizontally with Shift+MouseWheel
Better logic was implemented for managing horizontal scroll maximums, especially when scrolling vertically.
Scroll API
New programmatic scroll methods were added that allow for aligning an anchor line to the top/center/bottom of a view with a specified pixel displacement, or scrolling by pixels.
Margins
Line Number Customization
The first view line renders with line number 121 due to a custom origin number set on the document
A new line number provider language service was added that allows for complete customization of how line numbers are rendered in the line number margin. In addition, a property was added to the document that sets the line number for the first line in the document, defaulting to one.
Indicator Glyphs
The rendering of built-in indicator glyphs was improved.
Text Rendering
The text rendering of long lines was improved.
.NET Languages Add-on
IntelliPrompt completion list toggle button filters were added for the various kinds of items displayed in the list. The IntelliPrompt completion filter UI (toggle buttons and tabs) only shows based on the available items in the unfiltered list. For instance, if there are no types in the list, no 'Types' toggle button filter is visible.
Roslyn Add-on
The optional Roslyn add-on was updated to use Roslyn v3.0.0.
Python Language Add-on
IntelliPrompt completion list toggle button filters were added for the various kinds of items displayed in the list. The IntelliPrompt completion filter UI (toggle buttons and tabs) only shows based on the available items in the unfiltered list. For instance, if there are no classes in the list, no 'Classes' toggle button filter is visible.
