Namespace: DevExpress.ExpressApp.ConditionalAppearance

Assembly: DevExpress.ExpressApp.ConditionalAppearance.v18.1.dll

Declaration

public string BackColor { get; set; }
Public Property BackColor As String

Property Value

Type Description
String

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:

Note

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 Product(Session session) : base(session) { }
    public string Name {
        //...
    }
    public decimal Price {
        //...
    }
    public ProductStatus Status {
        //...
    }
    public Category Category {
        //...
    }
}
