ChartRangeControlClientDataProvider.SeriesDataMember Property

Gets or sets the name of the data field whose values are used to automatically generate and populate the series of a chart range control client.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v20.1.dll

Declaration

[XtraSerializableProperty]
[DefaultValue(null)]
public string SeriesDataMember { get; set; }
<XtraSerializableProperty>
<DefaultValue(Nothing)>
Public Property SeriesDataMember As String

Property Value

Type Default Description
String

null

A String value that specifies the data field's name.

Remarks

When a data source is assigned to the ChartRangeControlClientDataProvider.DataSource property, define the name of a data column upon which new series will be created, via the SeriesDataMember property. Then, assign the required data fields to the ChartRangeControlClientDataProvider.ArgumentDataMember and ChartRangeControlClientDataProvider.ValueDataMember properties.

To specify the SeriesDataMember property for the chart range control client, you should access the ChartRangeControlClientDataProvider object using the ChartRangeControlClientBase.DataProvider property.

Examples

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

In order to provide data to a chart date-time range control client, you need to 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 date-time 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 date-time range, customize template view and grid options).
