TimeSpanChartRangeControlClient.Range Property

Provides access to the range settings of the time-span chart range control client.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v19.2.dll


public TimeSpanChartRangeControlClientRange Range { get; }

Property Value

Type Description

A TimeSpanChartRangeControlClientRange object that contains settings to customize the range of the time-span chart range control client.


Use the Range property to access the time-span chart range control client's range settings. After that, you can set the TimeSpanChartRangeControlClientRange.Min and TimeSpanChartRangeControlClientRange.Max properties to define a custom range or use the automatic range calculation (the ChartRangeControlClientRange.Auto is set to true).


This example demonstrates how to configure a range control with the time-span chart client to display a chart with time-span data in the range control's background.

In order to provide data to a chart time-span range control client, access the ChartRangeControlClientDataProvider object using the ChartRangeControlClientBase.DataProvider property and assign a data source to the ChartRangeControlClientDataProvider.DataSource property. Then specify the required data fields via the ChartRangeControlClientDataProvider.ArgumentDataMember, ChartRangeControlClientDataProvider.ValueDataMember, and ChartRangeControlClientDataProvider.SeriesDataMember (optional) properties.

In the current example, a time-span chart client is bound to a simple data table containing three columns ("Argument", "Value", and "Series").

In addition, this example shows how to customize chart client common settings (e.g., change the time-span range, customize template view and grid options).

            rangeControl1.Client = timeSpanChartRangeControlClient1;

            // Generate a data table and bind the time-span client to it.
            timeSpanChartRangeControlClient1.DataProvider.DataSource = CreateChartData(100, 2);
