DevExpress WPF v20.1 full version download
Accordion Control
Limited project selection
The new API allows you to prevent the selection of accordion items.
- The CanSelect attribute specifies whether the accordion item can be selected.
- The CanSelectItem event allows you to prevent items from being selected based on conditions.
Show pop-up window on hover
Use the new ShowPopupOnHover property to show pop-up windows on mouse hover.
When the mouse pointer leaves the pop-up window, the Accordion control delays to hide the pop-up window. The delay is specified by the PopupHideDelay property.
Charting
Big Data Source Processing (CTP)
v20.1 introduces a new data processing option (XYSeries2D.AllowResample) to minimize memory usage when processing very large data sets. 2D charts with sorted numeric parameters and values will automatically enable this option.
Calculated field
This version includes support for calculated fields, which allow you to apply expressions to data source fields.
<dxc:ChartControl.CalculatedFields> <dxc:ChartCalculatedField FieldName="CalculatedPopulation" DisplayName="Calculated Population" FieldType="Double" Expression="IIF ([Gender] == 'Male', [Population] * -1, [Population])"/> </dxc:ChartControl.CalculatedFields>
Enhanced margin
- You can specify margins separately through the new Range.StartSideMargin and Range.EndSideMargin properties.
- The Range.SideMarginSizeUnit property allows you to specify the unit of measurement used to define the margin. Two options are available: axis unit (default) and axis range percentage.
Edit comments at runtime
End users can now create text and image annotations through ribbon commands (Add Text Annotation/Add Image Annotation).
If the RuntimeEditing option is enabled, the end user can change the existing annotation-edit the text and replace the image, or delete it with the Delete key.
Chart Toolbar
WPF Chart Toolbar allows you to quickly customize chart elements, end users can print charts, call Chart Designer, change the screen data range, etc. The toolbar content is customizable-you can add your own items (commands) and hide items you think are unnecessary, and you can use the ribbon or traditional toolbar for charts.
New DateTime axis mode
v20.1 includes a new SkipRangesWithoutPoints option. Enabling it can automatically exclude all axis ranges without data points. This feature is particularly useful for financial charts. You no longer need to manually define non-working date intervals.
Constant Lines-runtime editing
End users can now add constant lines through the Ribbon command (add vertical constant lines/add horizontal constant lines), end users can move constant lines, edit their titles or delete the lines (via the Delete key).
Side Points
v20.1 includes new Side Points chart elements, you can configure marks and labels for the first and last sequence points, independent of other sequence points.
