ASP.NET Controls

New Diagram (CTP) - The new ASP.NET Diagram for WebForms allows you to incorporate information-rich diagrams, flow charts and organization charts with ease. The Diagram control is available as a community technology preview. Features include:

  • 35+ Predefined Shapes
  • Custom Shapes
  • Bind to Any External Data
  • Shape Sizing and Drag-and-Drop
  • Collapsible Containers
  • Auto Layout
  • ReadOnly Mode
  • Configurable Page Settings
  • Export to SVG, PNG and JPEG
  • Zoom and Auto Zoom
  • Full Screen and Simple View Modes

CardView

  • Edit Form Layout - Customization API - New server-side and client-side API allows you to customize the Edit Form at runtime. You can now specify item caption and toggle item/group visibility on the fly.
  • Configurable Data Export - The new BeforeExport event allows you to configure export settings in code.
  • Real-Time Summary Computation Updates in Batch Edit Mode - The Data Grid, CardView and Vertical Grid controls can now recalculate summaries on the client-side in batch edit mode. Summaries now reflect all real-time changes to grid cell values.

Charting

  • Waterfall - This release includes a new Waterfall chart type. Waterfall charts can help visualize positive and negative changes to values across a given time period.
  • Box Plot - This release includes a new Box Plot chart type. Box Plot charts help you visualize data distribution across a six number summary (minimum, first quartile, median, third quartile, maximum and mean). Any data not included between minimum and maximum values are plotted as an outlier with a small circle.
  • TimeSpan Axis Scale Support - v19.2 introduces full support for TimeSpan scales. You can plot your TimeSpan data as-is or specify a custom aggregation mode. TimeSpan data can be mapped to an X-Axis, Y-Axis or both.
  • New Default Appearance Schema - v19.2 updates the default appearance schema for the WebForms and MVC Chart controls.

Gantt (CTP)

  • Node Editing - The following edit actions are available:
    • Resize and modify tasks
    • Change dependencies between tasks
    • Edit cell values within the Tree List region. The component immediately saves changes on the server and updates the Gantt chart when cell values change.
  • Change History - The DevExpress ASP.NET Gantt control stores changes made by an end-user. Changes can be rolled back if necessary.
  • Real-time Scaling - The DevExpress ASP.NET Gantt control allows you to browse data across various levels of detail. Hold the CTRL key and rotate your mouse scroll wheel to zoom (in or out).

GridView

  • Edit Form Layout - Customization API - New server-side and client-side API allows you to customize the Edit Form at runtime. You can now specify item caption and toggle item/group visibility on the fly.
  • Configurable Data Export - The new BeforeExport event allows you to configure export settings in code.
  • Real-Time Summary Computation Updates in Batch Edit Mode - The Data Grid, CardView and Vertical Grid controls can now recalculate summaries on the client-side in batch edit mode. Summaries now reflect all real-time changes to grid cell values.
  • New API
    • ToolbarItem.VisibleInBatchEditPreviewChanges - Allows you to display custom toolbar items when in Preview Changes mode.
    • AdaptiveDetailLayoutProperties.Items.AddCommandItem - Allows you to include Command Column items into a customized Adaptive Detail Layout.
    • SettingsHeaderFilter.DateRangePickerSettings.PickerType - Specifies picker type within the Data Edit column’s Header Filter.
    • The Columns.Add method overload allows you to create cell bands in MVC using model-based properties and lambda expressions.

Grid Lookup

  • The Grid Lookup now offers improved data selection performance when used in server mode (when the component loads the first time on a page).

File Manager

  • FileManager can now display folders with the same name when connected to a cloud service.

Pivot Grid

  • Aggregation at Any Level - This release includes an optimized Pivot Grid calculation engine for WinForms, WPF and ASP.NET. This new engine provides a more versatile summary expression function. The scope of the function is unbound fields. The Aggr function aggregates data with a specific summary function against a specific set of dimensions. Aggr functions can be nested as needed (you can easily create the desired aggregation level within the Pivot Grid control). The Aggr function has the following syntax: Aggr(summaryExpression, dimension1, dimension2, ...) The first argument is a summary expression calculated against a data source field. It is followed by a set of dimensions whose values are grouped to calculate summaries for the first argument.
  • Window Calculations - You can now specify the following window calculation options:
    • Running Totals
    • Moving Calculation
    • Rank
    • Difference
    • Percent Of Total
    • Custom Window Expression
  • The new object model includes the following classes:
    • RunningTotalBinding
    • MovingCalculationBinding
    • RankBinding
    • DifferenceBinding
    • PercentOfTotalBinding
    • WindowExpressionBinding
  • These enhancements are available when the new Optimized calculation engine is activated.
  • Direct Data Access in Client Mode - The data engine loads data to local in-memory storage. This local storage is optimized for frequent calculations with typed data sets and guarantees data integrity. Some large data sets, however, may require require too large a memory footprint (which can, in turn, slow down an application). With this release, it adds a DirectDataAccessInClientMode option. When the DirectDataAccessInClientMode option is enabled, the calculation engine does not upload source data to temporary storage. This avoids performance degradation in Client mode when working with large volumes of data (and when frequent re-calculations are unnecessary). This option cannot be used if using the PivotGrid in Legacy mode.

TreeList

  • Configurable Data Export - The new BeforeExport event allows you to configure export settings in code.

VerticalGrid

  • Configurable Data Export - The new BeforeExport event allows you to configure export settings in code.
  • Real-Time Summary Computation Updates in Batch Edit Mode - The Data Grid, CardView and Vertical Grid controls can now recalculate summaries on the client-side in batch edit mode. Summaries now reflect all real-time changes to grid cell values.

Accessibility

  • Accessibility enhancements allow the GridView, TreeView, File Manager and DateEdit components to better address W3C guidelines and standards.

Data Validation

  • To improve data integrity, Data Range validation checks data editor values (including editors in the grid's edit form) even if values stay the same.
  • The SpinEdit, ComboBox and RadioButtonList editors now support null value validation.

ASP.NET Core Controls

ASP.NET Core 3 Support
