LoginDesigner.UsePreviewControl Property

Note: This property is new in the .NET Framework version 2.0.

Gets a value indicating whether the designer should use a temporary copy rather than the actual control associated with the designer to generate the design-time markup.

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

protected override bool UsePreviewControl { get; }
/** @property */
protected boolean get_UsePreviewControl ()

protected override function get UsePreviewControl () : boolean

Property Value

Always true.

Because the UsePreviewControl property is always true, the designer ViewControl property returns a copy of the associated Login control to generate the design-time markup. The ViewControl property creates the copy by persisting the actual Login control, then parsing the persisted control string. The copied control does not affect any persistence for the Login.

If the UsePreviewControl property has been overridden to return false, the designer uses the associated Login itself to generate the design-time markup, and design-time changes to the control will persist to the page markup source.

Notes to Inheritors You can override the UsePreviewControl property to return false or to determine its value based on whether the control is marked with a class-level SupportsPreviewControlAttribute attribute. If the UsePreviewControl is not overridden, the Login control ignores the SupportsPreviewControlAttribute.
