Series.FilterCriteria Property

Gets or sets the current filter criteria. This is a dependency property.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v23.2.dll

NuGet Package: DevExpress.Wpf.Charts


public CriteriaOperator FilterCriteria { get; set; }

Property Value

Type Description

The current filter criteria.


Use the FilterCriteria property to create a filter expression that consists of different conditions applied to multiple data columns, and apply it to the series data. All existing filters are reset after you change the FilterCriteria to a new value.

Use CriteriaOperator‘s descendants to specify the FilterCriteria property. Refer to Criteria Operators for more information.

a chart with an applied filter expression

Alternatively, you can use the Series.FilterString property to pass a filter expression. Note that the FilterString and FilterCriteria properties are dependent. If you update one property, it changes the other property. Refer to Criteria Language Syntax for more information on how to create filter expressions.

series.FilterString = "[ProductCategory]='Automation'";

You can also use the CriteriaOperator.Parse method to convert a filter string to its CriteriaOperator equivalent as follows:

series.FilterCriteria = CriteriaOperator.Parse("[ProductCategory] = 'Automation'");


The following example shows how to use FilterBehavior and AccordionControl to create a UI that allows you to filter chart series data. To apply a filter, bind a series’ Series.FilterCriteria to the FilterBehavior.ActualFilterCriteria property value.
