Enumeration Properties in Entity Framework
The example below illustrates how to implement Enumeration Properties in an Entity Framework Code-First class.
Note that ASP.NET Core Blazor applications ignore the ImageName attribute applied to enumeration values.
public TextOnlyEnum TextOnlyEnumProperty { get; set; }
public TextAndImageEnum TextAndImageEnumProperty { get; set; }
// ...
public enum TextOnlyEnum { Minor, Moderate, Severe }
public enum TextAndImageEnum {
[ImageName("State_Priority_Low")]
Low,
[ImageName("State_Priority_Normal")]
Normal,
[ImageName("State_Priority_High")]
High
}
To be able to use this enumeration type in design-time criteria editors, register it in the constructor of your ModuleBase descendant using the EnumProcessingHelper.RegisterEnum method as follows.
using DevExpress.Data.Filtering;
//...
public sealed partial class MySolutionModule : ModuleBase {
public MySolutionModule() {
InitializeComponent();
EnumProcessingHelper.RegisterEnum(typeof(MySolution.Module.BusinessObjects.MyClass.TextOnlyEnum));
//...
}
//...
}
