LoginViewDesigner.UsePreviewControl Property

Gets a value indicating whether the designer should use a temporary copy rather than the actual control that is 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 Value

Type: System.Boolean
Always true.

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

If the UsePreviewControl property has been overridden to return false, the designer will use the associated LoginView control 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 LoginView ignores the SupportsPreviewControlAttribute.
