WebZoneDesigner Class

Provides design-time visual support for WebZone controls.

Namespace:  System.Web.UI.Design.WebControls.WebParts
Assembly:  System.Design (in System.Design.dll)

[SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.UnmanagedCode)]
public abstract class WebZoneDesigner : ControlDesigner

The WebZoneDesigner class is the abstract base class for both WebPartZoneBaseDesigner and ToolZoneDesigner, which all the other zone designers inherit from. By inheriting directly from ControlDesigner instead of CompositeControlDesigner, it allows implementations of the GetDesignTimeHtml method that do not automatically clear the Controls collection, thus enabling the designer to render exceptions from child controls.

Like other designers in this namespace, WebZoneDesigner overrides the UsePreviewControl property to always return true.

Notes to Inheritors:

The WebZoneDesigner class does not have a public constructor, so you cannot inherit from it directly outside the System.Web.UI.Design.WebControls.WebParts namespace. Instead, use WebPartZoneBaseDesigner or ToolZoneDesigner.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
