What's new in WPF Elements 7
WPF Elements 7.0 now targets .Net framework 4.0. The main additions are the heatmap chart series, DataGrid filtering and DataGrid aggregates. You can read more information about these additions here. There have also been many other feature additions, improvements and bug fixes which are listed in the change log in the documentation that ships with WPF Elements.
The heatmap series takes an array of data and displays it as an image based on a color gradient that you provide. The heatmap series has been built with high performance in mind and is capable of rendering thousands of changing data points in real time.
The DataGrid now includes various UI options for filtering data columns. Filtering can be enabled by setting just a couple of properties. The DataGrid will do all the work for you by selecting the best editors to use for filtering the type of data in each column. Further properties are available for making custom changes to the filtering feature.
Aggregates are the results of functions applied to all the data in a single column. For example, the sum or average of all the data, the largest or smallest value or simply the number of rows. The DataGrid can easily be setup to display aggregates in the DataGrid footer, or/and in the headers of grouped rows. The most common aggregates are included in WPF Elements, and custom aggregates can be provided by implementing a simple interface.
New in WPF Elements 6.0
WPF Elements 6.0 includes a huge amount of improvements, features, performance enhancements, bug fixes and a couple of new controls. This page lists all the major changes.
The main new control in WPF Elements 6.0 is the Ribbon control. This control is inspired by the Microsoft Office applications and serves as a replacement for the out-dated Menu control. All the main commands for your application can be exposed in the Ribbon as controls such as buttons, ComboBoxes and Galleries. Controls can be categorized in a tree-like structure for easy discoverability. The Ribbon control uses a smart layout algorithm to optimize the arrangement of the controls within the available space.
Included with the Ribbon control is the Gallery control which provides a way for users to select items from a list right within the Ribbon control.The items can be templated in any way and can optionally be categorized.
Axis arrangement features
The chart axes have a couple of new properties that let you position them on any side of the chart and reverse the scale.
Improved DateTime axis support
DateTimes have always been supported, but now the axis is more smart about how it spaces out the tickmarks and labels. Based on the visible range of data, an appropriate date-time interval is selected such as 3 months, or 2 days, or 6 hours etc. As the chart zooms, the date-time interval dynamically changes so the axis labels always looks great and easy to read. This logic is also fully customizable.
A new feature in the existing BarSeries class makes it easy to create tornado charts.
Right aligned numbers in DataGrid
A common way to display numbers in a table is to have them right aligned within their cells. A new display template option in the DataGrid makes this simple.
PropertyGrid style improvements
In all themes of the PropertyGrid, the property names are now left aligned and indented to make it easier to read hierarchical data, lists and nested objects. More animations have also been included.

New in WPF Elements 5.1
WPF Elements 5 is a massive update to the collection and ships with a wide range of new controls, improvements, bug fixes and performance enhancements. This page lists the major changes; hundreds more are contained within.
WPF Elements 5 debuts the super fast Datagrid control. With its highly tuned virtualization core the Datagrid can display millions of entries while remaining highly responsive. Full support for standard WPF data binding is available, as well as extensive support for styling and custom editors. A rich set of options are available for customization including sorting, frozen columns, paging controls and much more.
The new Time Explorer control makes it easy to select a date range relative to plotted data. A range can be selected by dragging the mouse, or using the scroll bars. The explorer can be zoomed using the mouse wheel. Any cartesian chart can easily be embedded within the Time Explorer.
Autocomplete Editor improvements
The Autocomplete Editor box now allows multiple entries to be entered while repeatedly displaying the suggestion drop-down box. Entries can be separated with whitespace or commas.
Dozens of fixes and improvements have been applied to all five included themes which are now offered free of charge, so make sure you check them out.
All new color pickers
WPF Elements 5 includes several great new ways to select colors, and dozens of palettes to select them from. Menu items can be added (for instance buttons or popups) allowing your users fast access to related commands. The new HSV color picker can be embedded inside one of these, for instance.
New chart types - polar charts
Polar charts show data using radius and distance from a centre point, instead of X-Y coordinates. Polar line, polar scatter and polar bubble charts are supported, which allow data to be displayed in a striking way without implying sequence.
Performance tuning and bugfixes
Hundreds of small improvements have been made across all controls ensuring they perform lightning quick and remain highly stable. In particular the rendering of all charts and the Scheduler control has been significantly improved, and the built-in themes have been refactored resulting in further performance enhancements across all controls.
New in WPF Elements 4.1
WPF Elements 5 benefits from all the performance tuning done across the Silverlight Elements and Phone Elements products. Bringing the performance required to run silky smooth controls on a resource constrainted device such as a cell phone up to our WPF product line means WPF Element 5 is blazingly fast!
New chart types - rose charts
Rose charts are the polar equivalent of bar charts. They're a striking way to present data sets where the elements are cyclical, such as monthly values, or where the order isn't important. WPF Elements can do normal rose charts or stacked rose charts (the latter shown here).
New chart types - radar charts
Radar charts are the polar equivalent of area charts. They're a great way for users to compare different aspects of data sets, for example to draw out the relative strengths and weaknesses of two products or plans. Overall WPF Elements 5 includes 12 polar chart types including polar line, polar scatter and polar spline series.
Charting improvement: step improvements
We've made a whole bunch of improvements to chart axes. For example, label frequency can differ from axis marker frequency to help deal with larger numbers of marker labels in an attractive way. This can be specified easily in the XAML mark up for any chart. Of course, if labels were to overlap the WPF Elements Charts will automatically skip labels by default to ensure charts are readable.
Charting improvement: title visibility improvements
Another nice simple axis enhancement is control over the axis title visibility. Easily configured in XAML or code.
Charting improvement: minimum range specification
Also on chart axes, you specify the minimum range a user can zoom into on a per-axis basis.
