機能

• FlexGrid for WinForms Enhancements
  • New Column Filter UI - Redesigned built-in column filters with a modern, intuitive tabbed UI that separates value filters from conditional filters. Plus, added new distinct, null and non-null filtering options.
    • The new UI changes are nearly 100% backward compatible with full theming support. If you've customized the previous UI, you will need to update your code.
      • ConditionFilter.Condition1 and Condition2 should be replaced with ConditionFilter.Conditions[i].
      • ConditionFilter.AndCondition is replaced by ConditionFilter.Conditions[i].IsAnd.
      • The following ColumnFilterEditor properties related to the drop-down menu have been removed and are considered obsolete: UseComposedMenu, UpdateMenu, MenuToolStrip, and MenuFilters.
      • For custom filter editors inherited from the ColumnFilterEditor, you can set the FilterEditor.Text property to set the tab header for the filter.
  • Search Match Count - The FlexGrid searching feature now allows developers to retrieve the number of matched records for enhanced search result feedback.
    • The ApplySearch method has a new output parameter from which you can retrieve the number of matches.
    • Improved Scrolling by Column - Added control over whether the first or last row/column appears partially during scroll using new flags: ScrollByRowColumn, EnsureFirstVisible.
• FlexChart for WinForms Enhancements
  • New Common Charting Library (C1.Chart) - A shared charting API across all .NET platforms. Note that there are no breaking changes except a namespace update. You may need to add "using C1.Chart" to your C# code files.
  • Column Radar Chart Type - FlexRadar now supports Column chart types with stacking options. This is great for wind rose charts, which are commonly used to visualize wind speeds at a particular location.
  • Axis Enhancements - New axis break and scrolling enhancements allow you to fine-tune your data visualizations.
    • New Axis Breaks feature allows you to skip value ranges on axes for cleaner presentations.
    • New Axis.RangeChanged event allows you to update the chart after the user scrolls or pans the chart.
    • New AxisScrollBar.Position property allows you to programmatically set the scrollbar position.
  • Text Annotation Rotation - You can now rotate text annotations in FlexChart by setting the Annotation's Angle property.
• Other WinForms Enhancements
  • New ToggleSwitch Control - A modern, theme-compatible toggle switch for forms and settings.
  • Enhanced UI Automation for C1Input - Improved accessibility and support for automated testing across controls like C1DateEdit, C1CalendarView, C1FontPicker, and more.
