Latest maintenance release.

Fixes

• Fixed issue with the display of null values in conjunction with a bug in the .NET Framework. This bug can result in a cell displaying an invalid value instead of a blank (null) value, for instance when scrolling or when receiving an update from the data source.

Adds intuitive column based search option to the data grid.

Features

• Data Grid
  • Auto Filter Row - This update includes an intuitive column based search option. By enabling the Auto-Filter Row (displayed at the top of the grid), users can filter grid contents by individual column values. You can control the search operators used (LIKE, EQUALS, etc.) based on the data type associated with each column.
  • New Item Row - Inspired by Outlook, the Data Grid's New Item Row allows end-users to add new records within the Data Grid. It can be displayed above or below all data/group rows. New API events allow you to initialize and update new records.
  • API Enhancements - The new CellValueChanging event fires when an end-user changes a cell editor's value, and allows you to cancel the changes made, or implement custom value processing/posting.
• .NET Core 2.0 - With this release, DevExpress UWP controls are based on .Net Core 2.0.

Spreadsheet control now supports all shape types.

Features

• Accordion Control
  • Navigation Pane Mode - A new Navigation Pane mode allows you to create an Outlook-inspired side bar panel and integrate it with the WPF Office Navigation Bar control.
• Chart Control
  • Custom Units of Measurement - You can now aggregate data by a custom unit of measurement (e.g. 15 minutes, 4 hours, etc.) You can also define a custom function that aggregates values using custom rules without modifying the source collection.
  • Crosshair Cursor Enhancements - New features include:
    • Display values of series points that are selected by the Crosshair Cursor in a legend.
    • Crosshair Cursor Lines (argument and value) follow the mouse cursor simultaneously.
    • The ability to display the Crosshair Cursor in the exported/printed chart.
    • The ability to display any data source field value within the Crosshair Cursor's Label.
  • Top N and Others - With this release, you can limit the amount of information displayed by a chart and visualize data more effectively. You can adjust the number of points included in the Top N group. All other points will be aggregated into the "Others" group.
  • Multi-Select Enhancements - You can select multiple items by drawing a rectangular region with the CTRL key pressed.
• 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.
  • TrackBarEdit - Custom Ticks and Steps - In v18.1, the 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 the WPF Data Editors).
  • Token Editors - Show Selected Items - The 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, the 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.
  • Data Paging - v18.1 introduces Page Navigation for those who prefer to display and load data page by page. The new Data Pager supports all data source types and can be used on a standalone basis.
  • Performance Enhancements - Data summary and conditional formatting rules are now calculated much faster. Summary recalculations have been optimized by restricting recalculations to those items that have been affected by a property change.
  • Data Shaping Enhancements (ICollectionView) - When working with ICollectionView sources, the 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.
• Data Grid & Tree List
  • Band Separators - With this release, the WPF Data Grid and TreeList controls display thick band separators. You can specify separator color and thickness. You can also specify different appearance settings for root and nested band separators.
  • 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.
  • Best Fit Enhancements - The 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.
  • Scrolling Performance - Vertical scrolling has been optimized. It is now 15% faster.
  • INotifyDataErrorInfo Validation Support - The 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.
  • 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.
  • Document Scaling - This release introduces document scaling for the 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.
• Dialogs
  • Folder Browser and Open/Save File Dialogs - The DevExpress WPF Open File, Save File and Folder Browser Dialogs were first released as a community technology preview in v17.2. This update marks their official release. New enhancements include:

Batch modifications allow you to eliminate unnecessary server updates (visual, re-sorting, selection updates, etc.) and speed up grid performance. You update the grid once, after all necessary changes have been made on a client.
  • Bands - With this release, our Bootstrap Grid View control supports column header and data cell bands.
  • Cell Merging - Much like Microsoft Excel, the Grid's cell merging option allows you to improve usability by avoiding the duplication of common information. Neighboring data cells across different rows can be merged whenever they display matching values.
  • Column Resizing - End-users can now resize grid columns by dragging a column header's border.
  • Merged Column Grouping - The ASP.NET Bootstrap GridView now includes a 'Merge Column Groups' mode. In this mode, you can merge grouped columns by dragging the appropriate column header(s) to the group panel and arrange them across a line.
  • Header Filter - Instant Find - v18.1 introduces a simple and quick way to find column filter values. The Find Panel allows users to enter a search string and initiate a search against all filter values displayed in the header dropdown.
  • Server Mode - Binding to Large Datasets - The Bootstrap Grid View control now supports data binding in server mode. In this mode, the Grid View loads only the minimum amount of data required for display purposes and delegates all data processing (such as grouping and sorting) to the database server.
  • Insert Bootstrap Control Wizard - The ASP.NET Core Bootstrap control suite includes an Insert DevExpress Bootstrap Control wizard. This wizard allows you to generate boilerplate code for DevExpress Bootstrap controls within your ASP.NET Core applications.
  • Navigation
  • New ASP.NET Core Bootstrap Toolbar - The ASP.NET Core Bootstrap Toolbar Control allows you to supply your web application with a lightweight adaptive toolbar interface. A toolbar is presented as a set of buttons arranged across groups.
  • ASP.NET Core Bootstrap Popup Menu - The DevExpress ASP.NET Core Bootstrap Popup Menu is a context sensitive menu that can be associated with a control on a web page.
