Last week we posted about a new Markdown syntax language and new code block selection features coming to our SyntaxEditor code editor in the next 2013.1 maintenance releases of our WPF and Silverlight control products.

In today's post, I'd like to show off another major new feature that will be available:  auto-case correct.

Auto-Case Corrector Services

In the upcoming version, a new AutoCaseCorrector language service is included that can perform case-correction on documents as editing occurs.  This feature works out of the box on any languages (including your own custom ones) that use dynamic lexers, where the case sensitivity of patterns is set to AutoCorrect.

The new language service class can also be inherited and updated to work with programmatic lexers as well, which is what we did in the Visual Basic language in the .NET Languages Add-on.

Auto-correct features will be enabled (if they are implemented for a language) as long as the new SyntaxEditor.IsAutoCorrectEnabled property is set to true.

Case Correct Example

Let's look at a Visual Basic example of this new feature in action.

In this screenshot, I typed in all lowercase on line 23.  Next I pressed the Down key to move to the next line.

The auto-case corrector noticed that I edited the line and moved the caret to a new line, so it went back to auto-correct the previous line.  Note how the For, As, Integer, and To keywords were all cased appropriately.

The auto-correct text change was performed as an undoable change too, meaning the user could undo (Ctrl+Z) it if they weren't happy with the update.

Summary

Auto-case correct is a wonderful addition for any languages that use case-insensitive keywords, such as Visual Basic.  It will greatly improve the end user's editing experience, and is enabled on our Visual Basic, VBScript, and PowerShell languages.

This and other features are ready to go for the upcoming 2013.1 maintenance release, due soon.

Yesterday we talked about the new code block selection features coming to our SyntaxEditor code editor in the next 2013.1 maintenance releases of our WPF and Silverlight control products.

Today I'd like to announce that we're including a new free sample syntax language for Markdown as well.

Markdown Syntax Highlighting

The screenshot above demonstrates some of the Markdown syntax highlighting features that are included.

Summary

If you have an app that edits Markdown source, then SyntaxEditor with its free new Markdown language will improve the editing experience for your end users.

This and some other exciting unannounced features are ready to go for the upcoming 2013.1 maintenance release, due soon.

We've been hard at work on new features, many of which relate to SyntaxEditor, for the upcoming 2013.1 maintenance releases of our WPF and Silverlight products.

A new feature coming to SyntaxEditor that is already in our WinForms version is called code block selection.

What It Does

Code block selection is a feature where the view's selection can be expanded to include containing code blocks, and then later contracted all the way back down to the caret as appropriate.

For instance, in C# the first time you expand the selection (via Ctrl+Num+), it may select the containing identifier.  By expanding it again, it may select the containing expression, then the containing statement, then the containing method.  And so on up the compilation unit.

By contracting the selection (via Ctrl+Num-), it goes back and selects the previously selected block.  Contracting can occur recursively to go back to the original selection.

This feature can be implemented in any language (very easily so if your custom language uses our LL(*) Parser Framework), and we've done just that for the advanced C#, VB, and XML languages we provide.

A C# Example

Let's see how this works in the C# language from our .NET Languages Add-on.

The cursor starts in WriteLine.

The containing identifier is first selected.

Then the containing expression. 

Then the containing statement, which in this case was the expression plus the semi-colon.  Next, the containing block is selected.

Finally the containing for statement of that block is selected.  If we would continue on, the method, class, etc. would be selected.

A XML Example

Now let's see how the XML language in the Web Languages Add-on works with this feature.

First the caret is in an attribute name.

Then the attribute is fully selected.

Then all attributes in the tag are selected.

Next, the entire tag is selected.

Then the containing element's content is selected.  This is great if you want to quickly press Del and replace the content of the element.

Finally, the entire tag block is selected.  If we would continue on, the parser element's content would be selected, then the parser tag block, etc.

Summary

You can see how this great feature can help with quick selection of containing code blocks.

This and some other exciting unannounced features are ready to go for the upcoming 2013.1 maintenance release, due soon.

The recent 2013.1 versions of our WPF, Silverlight, and WinRT XAML controls added full-size charts products.

One feature of our new Charts products are axes. Axes allow you to visualize the value range of your chart by labeling values.

Minimum and Maximum Values

Changing axis values such as Minimum and Maximum will determine what data displays on your chart and where. Here is the same data displayed in two charts. In the first, Minimum and Maximum are determined automatically.

In the second one, they are set manually to arbitrary values.

Axis Positioning

We have several capabilities to help you achieve the right look and feel for your application. The first is axis positioning, where you can place axes on either end of the chart.

Tick Intervals

Next is the ability to set the tick intervals. Here, we see two of the same chart. In the first, tick intervals are set to one month.

Grid

You can show major and minor ticks, and our grid feature allows you to extend those ticks behind the chart surface.

Styling Ticks

You can also style ticks to match your application.

Axis Labels

Axes can show labels on each major tick, and also a title. The angle of the labels is adjustable for when you need to put long labels on a small chart.

Summary

These are just a sample of some of the options available. There are a ton more. Download the trial and check it out!

Actipro Silverlight Controls 2013.1 has been released and is now available for download. This version adds a new full-size Charts product, a complete reimagining of the Sample Browser's UI, and some great new SyntaxEditor functionality.

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

Note:  Version 2013.1 updates the Silverlight controls to target the Silverlight 5 platform.

Our new full-size Charts product has been added, allowing you to create stunning charts for your apps.  See this announcement post and this first look post for a couple other chart screenshots.

Line Charts

A line chart renders quantitative data as a series of points connected by line segments. Lines can be straight, curved, or stepped. Markers can optionally be displayed based on type (such as first/last, high/low, negative, etc.).

Scatter Charts

Scatter charts render data points where each point is represented by a marker. Markers can use numerous built-in shapes or can be set to use custom shapes.

Area Charts

An area chart is a derivative of a line chart, where the area between the line and axis is filled in. As with line charts, areas can also be rendered using straight, curved, or stepped lines

Bar Charts

A bar chart displays rectangular bars with lengths proportional to the values they represent. Bar spacing can be set and the bars can be changed to render horizontally instead.

Indicators

A rich object model for supporting indicators has been added.  Indicators are special "tagged" regions of text that optionally display a glyph in the indicator margin and optionally highlight the text range with special styles.  Built-in indicators include bookmarks, breakpoints, and current statement indicators.  Custom indicators can easily be created as well.

See this bookmark indictors post and this debugging indicators post for much more detail on indicators and examples of functionality.

TextFormattingMode Support

SyntaxEditor's text rendering has been updated to support Silverlight 5's TextOptions.TextFormattingMode property setting.  This feature allows for improved text clarity.

Line Terminator Backgrounds

When a style that has a background encompasses a line terminator, it now will render the background of the line terminator's virtual character.

A new property BackgroundSpansVirtualSpace property has been added to highlighting styles that when set to true, will extend the background over a line terminator to cover all the way to the right edge of the view.

Trim All Trailing Whitespace

A new edit action has been added to trim all trailing whitespace in the entire document, regardless of the current selection.

CollectionTagger<T> Enhancements

The CollectionTagger<T> class has received a large number of new methods that make it easier than ever to manage a collection of tagged regions.

.NET Languages Add-on - Text Formatting

Text formatters have been added to the C# and VB languages in the .NET Languages Add-on, which beautify code by adjusting whitespace and making it more readable.

See this C# text formatter post and this VB text formatter post for more information and examples of the formatting results.

.NET Languages Add-on - Attribute IntelliPrompt

Full automated IntelliPrompt while editing C# and VB attributes is now included.

.NET Languages Add-on - Implicit Variable Type IntelliPrompt

Automated IntelliPrompt quick info now displays when hovering over var in C# or Dim in VB.

See this blog post for some more information and screenshots.
