FormViewDesigner.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 returns true.

Because the UsePreviewControl property is always true, the designer uses a View control that contains a copy of the associated FormView control to generate the design-time markup. The View control does not affect any persistence for the FormView. If the UsePreviewControl property has been overridden to return false, the designer will use the associated FormView itself to generate the design-time markup.

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 object. If the UsePreviewControl is not overridden, the FormView control ignores the SupportsPreviewControlAttribute.
