DataSourceCriteriaPropertyAttribute Class

Namespace: DevExpress.Persistent.Base

Assembly: DevExpress.ExpressApp.v20.1.dll

Declaration

[AttributeUsage(AttributeTargets.Property, Inherited = true, AllowMultiple = false)]
public sealed class DataSourceCriteriaPropertyAttribute :
    ModelExportedValueAttribute

<AttributeUsage(AttributeTargets.Property, Inherited:=True, AllowMultiple:=False)>
Public NotInheritable Class DataSourceCriteriaPropertyAttribute
    Inherits ModelExportedValueAttribute

Remarks

You can filter the data source for the List View displayed in a Lookup Property Editor or in the LinkUnlinkController.LinkAction Action's popup window. For this purpose, apply the DataSourceCriteriaProperty attribute to the target property. The constructor of this attribute accepts a string name of the CriteriaOperator type property whose value can be calculated in code as required (see DataSourceCriteriaPropertyAttribute.DataSourceCriteriaProperty). Below is an example of such a property:

public CriteriaOperator DepartmentsCriteria { get; set; }

Public Property DepartmentsCriteria() As CriteriaOperator

DataSourceCriteriaPropertyAttribute overrides DataSourceCriteriaAttribute when both attributes are applied to the same property.

Alternatively, you can use the IModelMember.DataSourceCriteriaProperty and IModelMemberViewItem.DataSourceCriteriaProperty settings that are available in the Application Model for the class members, ListView columns and DetailView items.
