Release History

Q2 2011 Beta 2

RadChart

What's New:

• Stacked 100 Bar, Line and Area series
• Scatter (XY) series – ScatterPoint, ScatterLine and ScatterArea
• Pan & Zoom behavior – the chart can be zoomed in/out and panned both horizontally and/or vertically
• Pan and Zoom may be specified programmatically
• Track ball behavior – allows extended data point information to be displayed upon Hold gesture
• Tooltip behavior – displays context-sensitive information about adjacent to the touch location data points
• Chart design-time gallery – Allows selecting pre-defined chart styles which causes XAML to be generated in the visual studio editor

What's Fixed:

• DateTimeContinuousAxis exception when plotting one or less points
• Problem with MVVM binding to numerical types other than Double
• Nullable numerical values were not recognized
• Numerous small bugs across the entire charting engine

Breaking Changes:

• Removed Axis.MajorTickStep property. It is now a member of CategoricalAxis and DateTimeCategoricalAxis. Use the following properties to specify major tick step for continuous axes:
  • NumericalAxis – MajorStep property
  • DateTimeContinuousAxis – MajorStep and MajorStepUnit
• DateTimeContinuousAxis.MajorStep is now of type double and specifies the number of units as described by the DateTimeContinuousAxis.MajorStepUnit

RadDataBoundListBox

What's New:

• CheckBoxes support

• Scroll offset persistence
• Improved BringIntoView logic

What's Fixed:

• Fixed a bug resulting in the DataRequest not being fired when calling BringIntoView to focus an item which is near to the end of the currently loaded scrollable list

Breaking Changes:

• Changed the returning type of the TopVisibleItem property from IDataSourceItem to object
• Removed the IsBusy, BusyContent and BusyContentTemplate properties
