Gets or sets the chart client’s data source.
Namespace : DevExpress.Xpf.Charts.RangeControlClient
Assembly : DevExpress.Xpf.Charts.v25.2.dll
NuGet Package : DevExpress.Wpf.Charts
public object ItemsSource { get; set; }
Public Property ItemsSource As Object
| Type | Description |
|---|---|
| Object |
An object that represents the data source from which the chart client retrieves its data.
|
The chart client can be bound to any object that implements the IEnumerable interface or its descendant (e.g., IList, ICollection). To bind a chart client, you should assign a data source to the ItemsSource property.
This example demonstrates how to use the date-time chart client for a range control to display a chart with date-time data within the range control’s viewport.
In this example a date-time chart range control client is bound to a System.Collections.Generic.List containing DateTimeItem objects.
Each DateTimeItem object contains Argument and Value properties, to which a date-time chart range control client is bound via its ChartRangeControlClient.ArgumentDataMember and ChartRangeControlClient.ValueDataMember properties.
