NuGet Package: DevExpress.ExpressApp

Declaration

[AttributeUsage(AttributeTargets.Property | AttributeTargets.Field, Inherited = true, AllowMultiple = false)]
public class ImagesForBoolValuesAttribute :

Remarks

By default, Boolean properties are represented in a UI via a check box:

BooleanPropertyEditor_1

When the ImagesForBoolValuesAttribute is applied to a property, it is displayed via a combo box containing the specified images:

BooleanPropertyEditor_4

The attribute’s parameter values are assigned to the IModelCommonMemberViewItem.ImageForFalse and IModelCommonMemberViewItem.ImageForTrue properties of the Application Model‘s BOModel | <Class> | OwnMembers | <Member> node. Additionally, these property values are set for the same properties of the Views | ListView | Columns | Column and Views | <DetailView> | Items | <PropertyEditor> nodes. You can set other values to these properties, in the appropriate node.

To add captions to the combo box, you can apply the CaptionsForBoolValuesAttribute:

BooleanPropertyEditor_3
