ThemeableAttribute Constructor (Boolean)


Initializes a new instance of the ThemeableAttribute class, using the specified Boolean value to determine whether the attribute represents a type or member that is affected by themes and control skins.

Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

public ThemeableAttribute(
	bool themeable


Type: System.Boolean

true to initialize the ThemeableAttribute to represent a type or member that can be affected by themes; otherwise, false.

Passing true to this constructor is equivalent to using the Yes field, while passing false is equivalent to using the No field.

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.)

namespace Samples.AspNet.CS.Controls {
    using System;
    using System.Web.UI;
    using System.Web.UI.WebControls;

    public class SomeDataBoundControl : DataBoundControl
        // Implementation of a custom data source control.

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