Series.ValueDataMember Property

Gets or sets the name of the data field which contains values for generated series points.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v24.1.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#

public string ValueDataMember { get; set; }

VB.NET

Public Property ValueDataMember As String

Property Value

Type	Description
String	A String value that specifies the data field name.

Remarks

Use the Series.ArgumentDataMember and ValueDataMember properties to bind a series to data. For more information, refer to Bind a Series to a Data Source.

Example

The following example demonstrates how to bind a DXCharts control to an MDB database.

To accomplish this, it is necessary to add a corresponding DataSet to a project, and set the Series.ArgumentScaleType, Series.ArgumentDataMember, Series.ValueScaleType and Series.ValueDataMember properties to the required values.

Then, in a code-behind the Window.Initialize method, you can obtain all data from a DataSet, using the data adapter’s GetData method, and assign this data to a series’ Series.DataSource property.
