ChartRangeControlClientDataProvider.ArgumentDataMember Property
Gets or sets the name of the data field that contains the arguments of the chart range control client’s points.
Namespace: DevExpress.XtraEditors
Assembly: DevExpress.XtraEditors.v18.2.dll
Declaration
[XtraSerializableProperty]
[DefaultValue(null)]
public string ArgumentDataMember { get; set; }Property Value
| Type | Default | Description |
|---|---|---|
| String | *null* | A String value that specifies the data field name. |
Remarks
Use the ArgumentDataMember property to specify the bound data source’s data field from which the chart client provider of the range control obtains its point arguments.
To specify the ArgumentDataMember property for the chart range control client, you should access the ChartRangeControlClientDataProvider object using the ChartRangeControlClientBase.DataProvider property.
Example
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).
