#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. |
#Remarks
The following UI elements can change their background color:
- Data cells in a GridListEditor, ASPxGridListEditor and DxGridListEditor
- Nodes in a TreeListEditor and ASPxTreeListEditor
- Property Editors that are inherited from the DXPropertyEditor, WebPropertyEditor and BlazorPropertyEditorBase types

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 Grid

//...
[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; }
}
