WebZone.HasHeader Property

Definition

Gets a value indicating whether a zone has a header area.

protected:
 virtual property bool HasHeader { bool get(); };
protected virtual bool HasHeader { get; }
member this.HasHeader : bool
Protected Overridable ReadOnly Property HasHeader As Boolean

Property Value

true if the zone has a header area; otherwise, false. The default value is true.

Remarks

The HasHeader property is primarily used by control developers who are creating custom zones. It exists as a flag so that the Web Parts control set renders a header only when appropriate for a zone. For example, the HasHeader property overrides this property and returns false unless the page is in one of the modes that allow personalization. In this case, a header is not rendered for a WebPartZone control in browse mode, while in most other modes a header is rendered. For more information on display modes and enabling users to switch among them, see Walkthrough: Changing Display Modes on a Web Parts Page.

Tool zones (zones that derive indirectly from the WebZone class by means of the ToolZone class, such as EditorZone and CatalogZone) must have headers that appear only when the page is in the appropriate display mode. Because the HasHeader property is true by default, they do not need to override the property.

Notes to Inheritors

If you are creating a custom tool zone that derives from ToolZone, you can override the RenderHeader(HtmlTextWriter) method and provide rendering for your zone's header.
