Data Grid Control

Infinite Scrolling

Our WinForms Grid ships with an 'Infinite Scrolling' mode – allowing you to more efficiently display data from very large data sources. Once incorporated into your app, you will be able to load (and display) only a small portion of your data source at start up. New records will load and appear on screen as users scroll the Grid vertically. A new data binding mode will help you connect our WinForms Data Grid control to your data source, even when the entire record count is unknown or infinite by nature (like a web service).

Demo  Documentation
Requires installation of WinForms Subscription v18.1. Download

Binding Selection to Data Source

In multiple row selection mode, you can sync row selected states with a Boolean field in the bound data source. The selection binding mode ensures that row selection persists whenever you filter or group grid data.

Selection binding mode was designed to be used in conjunction with the Web-Style Row Selector (the built-in Selection column). You can, however, use it when the built-in Selection column is hidden.

We've also added support for data filtering against the built-in Selection column via the Auto-Filter row (you can display only selected, deselected or all rows).

  • Attribution Text
  • Custom Timestamp

New event handlers allow you to customize notifications dynamically (e.g., add interactive elements), and handle toast notifications that failed to show.

To test your WinForms apps on a developer machine, use a new smart tag action that creates the application shortcut in the Windows Start Menu at design time.

Splash Screens - Overlay Wait Form

v18.1 introduces an Overlay Wait form. The Overlay Form is a semi-transparent splash screen that runs in a background thread and prevents access to a control or form by displaying an overlay.

  • The Overlay wait form never locks up the main and operation threads when functioning in a separate thread.
  • You can bind the Overlay form to any control, not just the main UI form.
  • The transparent Overlay wait form overlaps the owner control in its entirety, and prevents an end-user from interacting with the underlying control.
  • You can resize and move the main form while the Overlay form is visible (if you bind the Overlay wait form to a control and perform a lengthy operation asynchronously).
  • Multiple animation options.
  • Its custom painting mechanism allows you to draw the Overlay wait form manually.

Scheduler Control

New Storage Mechanism

We've replaced our existing SchedulerStorage with SchedulerDataStorage. Its features include:

  • Labels and statuses can have their own data sources out-of-the-box.
  • Storage data isn't reloaded after each change in the underlying data source.
  • Previously, any data change fired the same 'CollectionLoaded' event, and it was impossible to identify what kind of operation was performed. The new storage provides various events for different action types.
  • Enclosing data operations with the BeginUpdate\EndUpdate methods is no longer required.
  • The new storage correctly recognizes any data modifications performed at the data source level.

SchedulerStorage will continue to be supported (for backward compatibility purposes).

You now have the ability to cancel selection in code. To cancel selection, set the Cancel property to 'True' within the SelectionChanged event handler.

Multiple Selection - DevExpress Charting

Data Editors

On Demand ItemsSource Initialization

With this release, DevExpress WPF Data Editors that use source collections (e.g. ComboBoxEdit, LookUpEdit, ListBoxEdit), no longer process the entire source collection at startup. Data editors traverse through source items until the selected item is found. This significantly improves startup time for forms with editors bound to large source collections.

We've also introduced a new option that prevents an editor from looking for an empty value in the source collection. This makes forms with empty editors load faster.

TrackBarEdit - Custom Ticks and Steps

In v18.1, our WPF TrackBarEdit exposes new collections that allow you to define custom ticks and steps. For example, you can create a track bar with non-linear steps to better control zoom factors.

SVG Validation Icons

This release includes new SVG icons for validation error indication (used by our WPF Data Editors).

Token Editors - Show Selected Items

Our lookup editors in Token selection mode (ComboBoxEdit and LookUpEdit) can now keep selected items visible in a popup.

Data Grid Control

Server-Side Data Processing with Any Data Source

This release introduces support for virtual data sources. With these sources, our WPF Data Grid can be bound to any data source, even if the record count is unknown. The Grid control only requests top N records and allows you to implement the required data operations supported by your data source.

  • You can connect the grid to data sources not supported by Server Mode (Web Services, NoSQL Databases, etc.).
  • A data source needs to expose an API to only return top N records (total item count is not required; sorting, filtering, and summary calculation operations are optional).
  • You can specify which data operations are allowed (e.g. an end-user can sort by columns A, C, and D, and the Search Panel can filter data using the StartsWith criteria). This prevents a user from overloading the database with non-optimal queries. The Data Grid automatically hides all UI elements for non-supported operations.
  • You can use the asynchronous API to access data (e.g., Entity Framework Async Queries).

In Virtual Source mode, the DevExpress WPF Data Grid can display data split across pages or allow users to navigate records via infinite scrolling.

Data Paging

v18.1 introduces Page Navigation for those who prefer to display and load data page by page. Our new Data Pager supports all data source types and can be used on a standalone basis.

DevExpress WPF Grid - Data Paging

Documentation

Performance Enhancements

Data summary and conditional formatting rules are now calculated much faster. We've optimized summary recalculations by restricting recalculations to those items that have been affected by a property change.

The DevExpress WPF Data Grid does not recalculate total summaries when a user sorts data.

Data Shaping Enhancements (ICollectionView)

When working with ICollectionView sources, our WPF Grid control delegates all data management operations (sorting, filtering, grouping) to ICollectionView. which imposes some limitations on core grid features.

With this release, you can overcome all ICollectionView limitations. Simply disable the 'AllowCollectionView' option, and allow our WPF Grid to perform all data management operations.

Nested Property Notifications

The DevExpress WPF Data Grid and TreeList controls can automatically update individual cells, sorting, grouping, filtering, and summary when nested property values change.

Note: Only the object wherein a property is defined needs to implement the INotifyPropertyChanged interface - There are no such requirements for other objects in the nested property path.

Documentation

Best Fit Enhancements

Our WPF Data Grid and TreeList controls now offer a 'Best Fit' option for Band headers. Best Fit calculates and applies the optimal width required for a band to fully display its contents. This functionality is available for end-users and via the Grid's API.

Documentation

Scrolling Performance

Vertical scrolling has been optimized. It is now 15% faster.

INotifyDataErrorInfo Validation Support

Our WPF Data Grid and TreeList controls automatically display validation errors within data source objects that implement INotifyDataErrorInfo. Unlike IDataErrorInfo, the INotifyDataErrorInfo interface notifies bound UI controls when a validation error occurs within a data source.

Documentation

Retain Scroll Position

The DevExpress WPF Data Grid and TreeList controls ship with a new option that helps the Grid retain scroll position when updating data.

This behavior is supported by all data update types (add/remove, data sorting, full data refresh), and has been designed not to impact performance.

Documentation

Document Scaling

This release introduces document scaling for our WPF Data Grid, TreeList, Pivot Grid and Chart controls. Scaling allows you scale down an oversized control to fit the paper's width, or scale up the control to print it across multiple sheets of paper.

VCL Controls v18.1

New Object-Relational Mapping Tool (Beta)

The VCL ExpressEntityMapping Framework is an object-relational mapping (ORM) tool that simplifies data access and management by converting relational data into objects, properties, and collections for use in code. With this tool, you can query data and implement business logic using entity models and an object-oriented approach instead of handling the low-level data access and constructing/executing SQL statements manually.

DevExpress VCL Object-Relational Mapping Tool

The ExpressEntityMapping Framework ships with the following features:

  • Support for the Code-First, Database-First, and Model-First approaches to application development;
  • A standalone application that helps you design entity models in a visual fashion, and generate classes based on them;
  • Transparent and controllable object-relational mapping via built-in attributes or registration functions;
  • Support for Oracle, Microsoft SQL Server, MySQL, Firebird, SQLite, and Microsoft Access database engines;
  • Comprehensive database generation, updates, and integrity validation based on definitions of your entity classes;
  • Advanced support for existing databases with the capability to prohibit changing their schemas;
  • Data access using FireDAC and dbGo ADO connection components – no additional connections are required in your existing applications;
  • A dataset component allowing you to bind entity objects to data-aware controls;
  • Easy-to-build object queries allowing you to retrieve, sort, and filter data using LINQ expressions, object-based criteria syntax, or plain text, including calculated conditions and a wide set of criteria operators and functions;
  • An advanced parser supporting a database-independent criteria string syntax;
  • Support for ordinal, real, enumerated, and Nullable types, string fields/properties of unlimited size, and BLOB data serialization;
  • Custom object identifiers (keys) allowing you to mark a field/property of any supported data type as a key by a corresponding attribute;
  • IEnumerable and IEnumerable<T> object collections and LINQ expression results.

DevExpress VCL Object-Relational Mapping Tool

Ribbon and Toolbars

This release adds the following enhancements:

  • A new Search Toolbar that follows the ribbon tabs displayed in the tab area;
  • A new editor that allows end-users to search toolbar/ribbon commands by their captions and display search results in a drop-down window. This editor is designed for use in two use-case scenarios: either standalone or when embedded in toolbars or ribbon groups. When embedded in the new Search Toolbar, the editor allows you to mimic the 'Tell Me' box available in modern Microsoft Office applications.

DevExpress VCL Ribbon and Toolbars

Data Export – Improved Performance

With this release, we've improved our data export engine’s performance and optimized memory usage when exporting data.

  • Grid Views without master-detail data presentation are now exported up to 8 times faster and use up to 4 times less memory than in previous releases.
  • The TreeList control’s data export is up to 9 times faster and consumes up to 13 times less memory when compared to previous versions.
  • XLSX export compresses XML files and streams compressed data to the resulting file without storing temporary XML files in memory.

Grid Control

Improved Customization Options

We've improved the quick band/column customization functionality with:

  • A three-state check box allowing users to toggle the checked state of all items on the list;
  • A check box allowing users to sort items alphabetically;
  • Ability to switch the checked state of selected items by pressing the Space key;
  • Ability to select multiple items by pressing and holding the left mouse button and moving the mouse pointer over them. In addition, end-users can hold down the Ctrl key to invert the selection and thus select non-contiguous items.

Miscellaneous Enhancements

  • We've added the ability to manage and apply conditional formatting rules in the Layout and Data Editor at design time.
  • The indicator cell for a row now displays a new icon in response to displaying an in-place Edit Form.

Hybrid Touch-Friendly Scrolling

With this release, we've added a scrollbar mode similar to that found in Universal Windows Platform (UWP) apps that run on Windows 10. This mode is a hybrid of the classic mode and the touch-friendly scrollbar mode introduced in v17.2. In the new mode, the scrollbar thumb appears when an end-user hovers the mouse pointer over a control or scrolls through its content. Hovering the mouse pointer over the scrollbar thumb or its movement path transforms the thumb to a traditional scrollbar.

Moving the mouse pointer away from the scrollbar reduces it back to the thumb. The thumb disappears if the mouse pointer is stationary or the control is not scrolled for some time.

You can enable the new scrollbar mode by switching the corresponding option in a skin (or look&feel) controller.

DevExpress VCL Hybrid Touch-Friendly Scrolling

PDF Viewer

Bookmarks and Hyperlinks

The VCL PDF Viewer now allows you to display bookmarks within its Navigation pane for PDF documents that include bookmarked sections. This release also adds support for hyperlinks (both external links and links to specific parts in a loaded document).

DevExpress VCL PDF Viewer - Bookmarks and Hyperlinks

Page Thumbnail Navigation

With v18.1, we've added navigation by page thumbnails. Page thumbnails represent miniature previews of document pages. The Page Thumbnails panel located in the Navigation pane allows end-users to do the following:

  • Navigate through the document by clicking page thumbnails;
  • Enlarge or reduce the thumbnail size;
  • Select thumbnails using mouse clicks combined with the Shift or Ctrl key;
  • Print pages which correspond to selected thumbnails.

Miscellaneous Enhancements

  • Multi-threaded content rendering improves performance when scrolling, zooming, or rotating pages;
  • The PDF Viewer can now display a 'Locked View' image when opening a PDF document. This is especially useful for large documents.

Scheduler Control

Google and Microsoft Office Calendars

v18.1 introduces a storage component that allows users to create, display, or modify appointments on Google and Microsoft Office calendars.

Accessing calendar data requires that you obtain OAuth 2.0 credentials for your application and specify them via the new authorization components introduced in this release.

DevExpress VCL Scheduler Control

Agenda View

Appointments can now be rearranged using drag and drop.

Skins Library

Vector (SVG) Skins

v18.1 adds full support for SVG (Scalable Vector Graphics) skins. The release ships with a new skin (The Bezier) first introduced in our WinForms product line and which is based entirely on SVG images. This new skin allows our VCL controls to look perfect on any screen with any DPI settings. The Bezier is the first skin that ships with UI elements that allow users to change the skin palette and instantly re-paint the entire skin at runtime. You can choose from dozens of unique palette presets or easily create a custom palette to apply a corporate style to your application.

Skin Editor Enhancements

This release adds the following enhancements:

  • The new tabbed MDI UI simplifies the manner in which you switch between skins and their elements.
  • The Project Manager and tabs allow you to reorder skins in a project using drag and drop and Move Up/Down buttons.
  • A Find Panel allows you to quickly locate skin elements in product groups.
