What's New

What's New in ComponentOne

Sparklines in WinForms

New in WPF: a modern, minimalistic Simplified Ribbon control that occupies the middle ground between a ribbon a toolbar, providing a single-line collapsed state, or a three-line ribbon-like appearance.

The new Control Wizard for ASP.NET MVC is a wizard that allows you to configure controls and generate code for C1 MVC controls.

WinForms' new Material Theme Designer allows you to set primary and accent colors of Material theme and save/load them in the C1themes format.

WinForms also features a new sparkline control with FlexGrid integration and even more chart animations.

WPF, UWP, and Xamarin have introduced C1Icon, a new icon that makes it even easier to customize icons in FlexGrid.

WPF and UWP Schedulers now feature TableView and AgendaViews, and XAML FlexChart now has animations for loading, updating, and changes to the chart axes.  You can also create your own custom animations using the AnimationTransform event.

UWP controls are now available through NuGet.

ASP.NET MVC's new Flight Statistics demo is a responsive dashboard that displays flight performance data over time. Controls include FlexGrid with sparkline columns for delay trend and KPI columns. A treemap, bar chart, and line symbol chart are used in to display region-wide statistics, and users can drill down to a specific region and city by selecting the data points.

ASP.NET MVC ComboBox grouping is now implemented as a simple property in the control itself.

In addition to FlexViewer's support for ActiveReports, a new Item Template allows you to quickly configure the viewer in your ASP.NET MVC app.

MyBI sample, a dashboard business intelligence application for mobile devices, uses gauges, charts, and a grid to summarize sales data, is now available for Xamarin.
