Actipro WPF Controls 2013.2 have been released and is now available for download. 

Major new features are described below.  See the announcement post for the detailed list of enhancements and updates.

PieChart

A new pie chart control has been added to complement our other bar, line, area, and scatter chart offerings.

The pie chart supports advanced features like multiple label positioning and display options, legend display, nesting of multiple series, hierarchical data, and more.

DonutChart

Donut charts have been added as well.  All the same features found in pie charts are found in donut charts, and the hole radius is fully configurable.

Axis Tick Labels for Percentage Stacked Charts

When using stacking bar or area charts with the percentage axis option, the percentage value labels now display on the axis.

Improved Scatter Chart Samples

A new and improved scatter sample has been added.

Improved Support for Touch

Ribbon buttons have been improved to support touch-based tapping.  Popups on all ribbon controls have also been updated to be positioned properly on tablet PCs that have the "right handed" option set.

Web Languages Add-on - Advanced JavaScript Language Implementation

A new advanced JavaScript language implementation has been added to the Web Languages Add-on.

The syntax language features syntax highlighting, parsing, AST building, syntax error reporting, code outlining, delimiter auto-complete, smart indent, text formatting, and code block selection.

See a summary of the new language in this previous blog post.

Delimiter Auto-Completion

Delimiter auto-complete is where the user types a start delimiter and a related end delimiter is auto-inserted after the caret.

In the screenshot above, the { character was typed and the } character was auto-inserted.  This feature has been added to several of the languages in our add-ons.

Delimiter Indent Provider

Curly brace auto-indent can now be easily added to any language, and it has been added to our C# and JavaScript languages in the add-ons.

When the caret is in the middle of a curly brace pair, pressing Enter normally will move the close curly brace to the next line with the caret right in front of it.  If you have an indent provider for your language, the close curly brace will be indented properly however it's still not an ideal situation because you generally want the caret to be on its own line before the close curly brace's line.

This scenario is where curly brace auto-indent comes in!  This feature injects a new blank line in between the braces, indents one more level, and positions the caret on that line.

Indentation Guides

Indentation guides are subtle vertical lines that render at each tab stop on lines prior to the first non-whitespace character.  They help visually align the indentation of visible code blocks.

You can see the silver indentation guide lines in the tab stops within this screenshot:

Whitespace-only lines are intelligent and render indentation guides based on the tab stop level of surrounding text.

Improved Code Fragments Performance

Lexer and token scanning performance has been improved when using our code fragments feature, which allows you to set header and footer text to surround the document's text for purposes of parsing.

Improved Printing Support

A custom highlighting style registry can now be set explicitly for printouts.  This is ideal if your editor is in a dark theme since then you can use an alternate highlighting style registry designed for light backgrounds on printouts.

Rendering of printouts has also been improved when the syntax highlighting option is off.

.NET Languages Add-on - IntelliPrompt Parameter Info for Array Indexers

Automated parameter info support has been added when the end user edits array indexers.

.NET Languages Add-on - Customizing Completion Items Sample

A new sample is now included that shows how to add and remove items from the C# and VB automated IntelliPrompt completion list.  This ability lets you filter out certain completion list items or add your own custom ones before the list is displayed to the end user.

Improved WindowChrome to Not Cover Auto-Hidden Windows Taskbar

In the past versions, WindowChrome (and thus RibbonWindow) would cover up an auto-hidden Windows taskbar when the window was maximized.  This issue has now been resolved, and the auto-hidden taskbar is now visible.

InertiaScrollViewer

The InertiaScrollViewer control is a drop-in replacement for the native WPF/Silverlight ScrollViewer control but allows you to scroll content using touch, similar to what you're used to on Windows 8 and mobile devices.

It reacts to dragging, flicking, mouse wheel, and normal mouse operation via the scrollbars. You can adjust properties like EasingFunction, VelocityTimeRatio, and VelocityDistanceRatio to fully control how inertia scrolling looks and feels.

In the screenshot above, you can see how our main Sample Browser pages have been updated with InertiaScrollViewer, allowing full touch interaction and navigation within them.

Last week we had a customer write us who was rehosting the Windows Workflow Designer in their own WPF application.  See these MSDN notes for documentation on how to do so.

The customer wanted to be able to use SyntaxEditor to create a custom VB Expression editor since it would allow them to have features like syntax highlighting and automated IntelliPrompt capabilities (via SyntaxEditor's .NET Languages Add-on).

In addition, the customer asked about being able to use our Docking/MDI product to add docking windows to host the designer's ToolBox and Properties windows.

We spent a few minutes and modified the Microsoft sample for rehosting the Windows Workflow Designer to integrate Actipro controls into it, and here's what we came up with:

You can see how tool windows (fully dockable) host the ToolBox and Properties views and the designer is hosted in the tabbed MDI area.  In addition, SyntaxEditor (in single-line mode and with the .NET Languages Add-on) is used to provide automated IntelliPrompt features for editing expressions. 

This really improves the UI experience for end users.  If you are rehosting the Windows Workflow Designer in your own WPF app and would like the full source of our integration example, please write us and we'll be happy to send it to you.

UPDATE:  Check out this newer blog post showing off enhancements for automated variable IntelliPrompt features.

Several weeks ago, we announced a new Delimiter Auto-Complete feature coming to the 2013.2 version of SyntaxEditor for WPF and Silverlight.  This feature is great because it improves typing efficiency by auto-inserting end delimiters when the start delimiter is typed.

We have been wanting to improve the typing experience even more and in today's post, I'd like to announce that curly brace auto-indent is also coming.

What Is Curly Brace Auto-Indent?

When the caret is in the middle of a curly brace pair, pressing Enter normally will move the close curly brace to the next line with the caret right in front of it.  If you have an indent provider for your language, the close curly brace will be indented properly however it's still not an ideal situation because you generally want the caret to be on its own line before the close curly brace's line.

This scenario is where curly brace auto-indent comes in!  This feature injects a new blank line in between the braces, indents one more level, and positions the caret on that line.

Sample Usage

Let's start with a regular JavaScript function declaration.  Note how the caret in in between a curly brace pair.

In the past, if you pressed Enter, you'd get this:

With the new curly brace auto-indent feature, instead of the above when you press Enter, you will get now this:

The end user is immediately able to start typing content for the function.

Summary

These new features will be available in the 2013.2 version of SyntaxEditor, and are built into our advanced C# and JavaScript languages for this version.

They can easily be added to any custom language as well with a few lines of code.

In today's post I'd like to announce another new feature coming to the 2013.2 version of SyntaxEditor for WPF and Silverlight:  indentation guides.

What are Indentation Guides?

Indentation guides are subtle vertical lines that render at each tab stop on lines prior to the first non-whitespace character.  They help visually align the indentation of visible code blocks.

You can see the silver indentation guide lines in the tab stops within this screenshot:

Whitespace-only lines are intelligent and render indentation guides based on the tab stop level of surrounding text.

Summary

These new features will be available in the 2013.2 version of SyntaxEditor!

One great thing about having our free Code Writer Windows 8 text/code editing app out is that we now get a lot of feedback directly from end users of the SyntaxEditor control.  Normally we only receive feedback from our own customers, who are developers integrating SyntaxEditor and our other UI controls into their own apps.

What is Delimiter Auto-Complete?

A common request we've received is to support delimiter auto-complete.  Delimiter auto-complete is where the user types a start delimiter and a related end delimiter is auto-inserted after the caret.  This is especially helpful when working on mobile tablets like a Surface since it means less overall typing is required to output the same code.

The 2013.2 version of SyntaxEditor for WPF and Silverlight includes a built-in implementation of delimiter auto-complete via a language service that can be customized and assigned to any syntax language.

Sample Usage

In this example, we'll use our new advanced JavaScript language, also coming in the 2013.2 version and described further in this post.

First, we'll type a ( character:

You can see how the related end ) is also auto-completed and the caret remains in the middle of the two delimiters. 

Now if I type a ) character, it recognizes that this end delimiter was auto-completed, and instead of making another text change, skips right over the previously auto-completed end delimiter.

Now if I type another ), it will insert a new character since it recognizes we are now outside of the auto-completed delimiter range.

Let's delete that extra end delimiter and type an open curly brace to see the resulting auto-completed close brace:

Say I made a mistake and wish to quickly delete the pair.  If I press Backspace then it recognizes I'm backspacing over a delimiter that created an auto-complete and it removes the completed end brace as well. 

That's neat stuff!

Summary

These new features will be available in the 2013.2 version of SyntaxEditor!
