Boolean Properties in Entity Framework

• Jun 11, 2019

The example below illustrates how to implement Boolean Properties in an Entity Framework Code-First class.

C#

// By default, a Boolean property is displayed via a CheckEdit control.
public bool BooleanProperty { get; set; }
// To use a drop-down control, specify captions with the CaptionsForBoolValues attribute.
[CaptionsForBoolValues("TRUE", "FALSE")]
public bool BooleanWithCaptions { get; set; }
// To display images in a drop-down, apply the ImagesForBoolValues attribute.
[ImagesForBoolValues("ImageForTrue", "ImageForFalse")]
[CaptionsForBoolValues("TRUE", "FALSE")]
public bool BooleanWithImages { get; set; }

VB.NET

' By default, a Boolean property is displayed via a CheckEdit control.
Public Property BooleanProperty() As Boolean
' To use a drop-down control, specify captions with the CaptionsForBoolValues attribute.
<CaptionsForBoolValues("TRUE", "FALSE")>
Public Property BooleanWithCaptions() As Boolean
' To display images in a drop-down, apply the ImagesForBoolValues attribute.
<ImagesForBoolValues("ImageForTrue", "ImageForFalse"), _
CaptionsForBoolValues("TRUE", "FALSE")>
Public Property BooleanWithImages() As Boolean

You can also specify captions and images via the following properties in the Model Editor:

• IModelCommonMemberViewItem.CaptionForTrue
• IModelCommonMemberViewItem.CaptionForFalse
• IModelCommonMemberViewItem.ImageForTrue
• IModelCommonMemberViewItem.ImageForFalse
