Control developers use the ThemeableAttribute attribute to decorate control types and their members, to signal which ones can and cannot be affected by themes and control skins. By default, all properties exposed by a control are themeable. However, themes are typically applied only to stylistic properties; the Themeable(false) attribute should be applied explicitly to all non-stylistic properties. Decorating a member with the Themeable(false) attribute ensures that the member is not themed, regardless of the value of the EnableTheming property. For example, if the ThemeableAttribute attribute is applied to a control and set to false, the control is not affected by themes even when its EnableTheming property is set to true.
The ThemeableAttribute class maintains a static list of all types that support themes, and this list is consulted whenever the static methods IsObjectThemeable and IsTypeThemeable are called.
The following code example demonstrates how you can apply the ThemeableAttribute attribute to a member of a control. In this example, ThemeableAttribute is applied to a data-bound control and false is passed to the ThemeableAttribute constructor, indicating that the DataSourceID member cannot have themes applied. (Passing false to the constructor results in a ThemeableAttribute instance that is equivalent to the No field.)

[Themeable(false) ] [IDReferenceProperty()] public override string DataSourceID { get { return base.DataSourceID; } set { base.DataSourceID = value; } } } }
