ChartRangeControlClientGridOptions Class

Represents the base class for classes that provide grid settings of the chart range control client.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v19.2.dll

Declaration

public abstract class ChartRangeControlClientGridOptions :
    ChartElement
Public MustInherit Class ChartRangeControlClientGridOptions
    Inherits ChartElement

Remarks

The ChartRangeControlClientGridOptions class serves as a base for the ChartRangeControlClientDateTimeGridOptions and ChartRangeControlClientNumericGridOptions classes, and declares properties that define the numeric and date-time grid settings of the chart range control client (e.g., ChartRangeControlClientGridOptions.GridMode, ChartRangeControlClientGridOptions.GridSpacing, ChartRangeControlClientGridOptions.SnapMode, ChartRangeControlClientGridOptions.SnapSpacing, etc.).

To learn how to integrate a chart control with the range control, see Integration with a Range Control.

Examples

This example demonstrates how the grid lines and grid snapping of the chart within the range control's viewport can be customized at runtime.

To access the client options of the chart inside the range control's viewport, use the RangeControl.ClientOptions property. In this example, the chart control contains data with date-time arguments, so this property returns an object of the ChartRangeControlClientDateTimeOptions type.

To access the grid properties (e.g., ChartRangeControlClientGridOptions.SnapSpacing, ChartRangeControlClientDateTimeGridOptions.SnapAlignment, ChartRangeControlClientGridOptions.GridSpacing and ChartRangeControlClientDateTimeGridOptions.GridAlignment) of the chart range control client, access the ChartRangeControlClientDateTimeGridOptions object using the ChartRangeControlClientDateTimeOptions.RangeControlDateTimeGridOptions property.
