機能

.NET Core 3 Preview 5 Support

• In addition to DevExpress assemblies built against .NET Framework 4.5.2, there are new packages built against .NET Core 3. These packages contain the same set of DevExpress WinForms controls and allow you to test your applications in the .NET Core 3 environment even before its official release.

Data Grid

• Find Panel - Parser Kind and Filter Condition - Implemented two new options that let you fine-tune how the data-aware controls (Data Grid, Tree List, Vertical Grid) parse a search string entered into the Find Panel.
  • Parser Kind. Specifies whether the control should look for all or any of the words in the specified search string.
  • Filter Condition. Options include: Contains, StartsWith, Equals, Like.
• New Format Rules: Highlight Cell Value Changes - Highlight a cell with a custom icon or color if its value increases, decreases, or simply changes. Custom appearance settings will be reset after the specified time interval elapses.
• Animated Format Rules - If you use a Format Rule to highlight cell value changes, you can enhance the presentation using the following animations effects:
  • Fade in / out effects for icons
  • Gradual color change
  • Animated progress bars
• Repeat Fixed Columns on Each Printed Page - Added an option to repeat left-fixed columns and bands if the control is printed out or exported to a page-based format (PDF, DOCX and RTF).

Charting

• Segment Colorizers - You can now use the following segment colorizers to enhance data visualization.
  • Trend Segment Colorizer
  • Range Segment Colorizer
  • Point-based Segment Colorizer
• Center-Align Axes - The Chart control allows you to center-align axes within the plot area.
• Y-Axis Label Rotation (Polar and Radar Charts) - Polar and Radar charts now allow you to display Y-axis labels at an angle.
• Axis Label Position and Alignment - The chart control introduces the following options:
  • Display axis labels inside or outside of plot region.
  • Change label alignment relative to tick marks (Near, Far, Center).
• Histogram - DevExpress Chart control now allows you to generate Histograms. Features include:
  • Histogram aggregation function.
  • Excel-inspired histogram calculation modes (automatic, bin width, bin number).
  • Interval information display within axis labels.
  • Customizable label text for Overflow and Underflow bins.
  • Ability to align grid lines and tick marks with bins and to center axis labels.

Diagram

• Collapsible Containers - Users can now collapse and expand container content. To activate this feature, set the DiagramContainer.CanCollapse property to true.
• Export to PDF

Data Editors

• PictureEdit - Image Editor Dialog - PictureEdit now supports simple edit operations in a separate Image Editor dialog: crop, rotate, adjust brightness and contrast, etc. Live preview and undo and redo operations are available. To invoke the dialog, end-users need to select Edit from the context menu.
• Simple Button - Light Paint Style - The new Light style was specifically designed so you can create a group of borderless buttons (SimpleButton, CheckButton and DropDownButton). If this new style is enabled, buttons render their background only when hovered or pressed/selected.
• Clear Text to Reset Edit Value to Null - Users can now clear an editor's text to reset its value to null. This behavior is controlled by the AllowNullInput option and supported by DevExpress data editors with the built-in auto-search functionality (PopupBaseAutoSearchEdit descendants): Combo Boxes, Look-up Editors, MRU Editor, etc. The new behavior is enabled for in-place cell editors and disabled for standalone editors by default.

Filtering UI

• Breadcrumb Style Filter Panel - The Filter Panel now supports a new visual style displayed in the image below. In this format, end-users can easily differentiate between colorized filter items, modify or clear individual filter conditions. This style is available in DevExpress WinForms Data Grid, Pivot Grid, Tree List, and Vertical Grid controls.
• Filter Editor: New Display Style - This release introduces a new display style for standalone and integrated Filter Editors. The new style renders filter conditions in an easy-to-read format and uses skin-defined colors to clearly distinguish between operands and operators.
• Expression Editor Customization - When end-users apply criteria-based format rules, they use the built-in Expression Editor. Now you can handle the 'FormatRuleExpressionEditorCreated' event to access and customize the this dialog. This event is available in the Data Grid and TreeList controls.
• Find Panel - Highlight Result Enhancements
  • The Find Panel integrated into the Data Grid, TreeList and Vertical Grid now highlights results in cells, even if cell text is formatted using HTML tags (RepositoryItemHypertextLabel).
  • If a search string contains two or more words, all found words are highlighted (even if found within the same cell). In previous versions, only one word was highlighted.
• Custom Functions - You can now create custom filter functions. Custom functions will be available to end-users in Excel-Inspred Filter Dropdowns and in "Custom Functions" menu in the Filter Editor. To add a custom function, enable the 'ColumnView.OptionsFilter.ShowCustomFunctions' property and handle the 'ColumnView.QueryCustomFunctions' event.
• New default editor for operands and operators Filter Builder dialog - Operands and operators in the GridControl's Filter Builder now use scrollable combo boxes as default editors.

Layout and Navigation

• New Toolbar Form - Inspired by the Visual Studio 2019 UI, the new ToolbarForm allows you to add bar items (buttons, editors, labels, submenu items) directly into the form's title bar.
• New TablePanel and StackPanel Controls - Two new lightweight panels allow you to build simple data entry forms without employing the Layout Control.
  • Stack Panel - inspired by the standard WPF StackPanel container, this panel arranges all of its child controls in a single column or row. Any control placed inside this panel can stretch to occupy all available space.
  • Table Panel - allows you to create a grid, where each cell can host a control. The grid supports column and row spans, meaning that a control can occupy several consecutive cells. Columns and rows support three sizing modes: absolute, relative, and auto-size.
• Compact Layout Mode - A new Project Settings option reduces padding and/or margin values for all controls that support DevExpress skins/themes. Use this option to display more information on screen in data-intensive applications.
• Layout Control - Acrylic Effect Support - The Layout Control now supports Acrylic accent (partial transparency) when it is placed on a DevExpress form.

Scheduler

• Appointment Slots for Office Hours, Meeting Availability, etc. - The WinForms Scheduler Control now supports Time Region objects that apply restrictions and appearance settings to time cells. You can use this functionality to disable individual time cells so that users cannot add new or modify existing appointments. For instance, you can block lunch hours or days off. Time Regions can be Resource-specific.
• Sort and Group Appointments Using a Custom Algorithm - New events allow you to group and sort appointments using custom algorithms:
  • CustomAppointmentGroup
  • CustomAppointmentSort
