Specifies the background color of UI elements affected by the conditional appearance rule generated from this attribute instance.

Namespace: DevExpress.ExpressApp.ConditionalAppearance

Assembly: DevExpress.Persistent.Base.v22.2.dll


public string BackColor { get; set; }

Property Value

Type Description

A string specifying the background color of UI elements affected by the conditional appearance rule. A value should be recognizable by the System.Drawing.ColorConverter class.


The following UI elements can change their background color:


It is not recommended to apply the same background color for all business class properties. This setting changes the background color of selected rows in the GridControl, so the selection will be invisible when rows with the modified background color are selected. Additionally, note that the font color depends on the current skin (see IModelApplicationOptionsSkin.Skin). So, ensure that the specified background color does not make the text unreadable in certain skins.

According to the rule demonstrated in the example below, the Product objects whose Price is more than 50 will be displayed in Red background using Maroon font color in List Views.

using DevExpress.ExpressApp.ConditionalAppearance;
[Appearance("RedPriceObject", AppearanceItemType = "ViewItem", TargetItems = "*",
    Criteria = "Price>50", Context = "ListView", BackColor = "Red",
        FontColor = "Maroon", Priority = 2)]
public class Product : BaseObject {
    public virtual string Name { get; set; }
    public virtual decimal Price { get; set; }
    public virtual ProductStatus Status { get; set; }
    public virtual Category Category { get; set; }

// Make sure that you use options.UseChangeTrackingProxies() in your DbContext settings.

You will find many examples demonstrated in the FeatureCenter demo installed with XAF. This demo is located in the %PUBLIC%\Documents\DevExpress Demos 22.2\Components\XAF\FeatureCenter.NETFramework.XPO folder, by default.
