Ultimate UI for Windows Forms 26.1.27 버젼 업데이트

기능

• .NET (Core) Only
  • Replaced BinaryFormatter with new custom Infragistics Serializer - this will be the default serializer for serialization. If the Microsoft Binary Formatter is enabled and your binary data is in the older format, the Microsoft Binary Formatter will still be used for deserialization.
• Breaking Change
  • The new custom serializer is forward compatible in regards to binary files generated with prior versions of the Ultimate UI for Windows Forms toolset. Files originally generated with the BinaryFormatter can still be read and deserialized using the new serializer. However, the BinaryFormatter used in prior versions does not have the ability to deserialize files generated in the new version
• New Chart Features
  • Range Bar Series - Added RangeBarSeries to UltraDataChart so you can render low-to-high ranges as horizontal bars by combining a CategoryYAxis with a NumericXAxis.
  • Added the Checkmark marker type to supported chart marker enumerations, including LegendItemBadgeShape.
  • Added a new MarkerSize property to chart series that support markers so you can set the marker width and height to an exact device-independent pixel size. Setting MarkerSize to NaN restores the default template-driven marker size, and the property also applies when using lightweight markers. BubbleSeries continues to use radius-based sizing, so MarkerSize does not override bubble radius values.
