LoginDesigner.UsePreviewControl Property

  • Reference

Definition

Namespace:
System.Web.UI.Design.WebControls
Assembly:
System.Design.dll

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.

protected:
 virtual property bool UsePreviewControl { bool get(); };
protected override bool UsePreviewControl { get; }
member this.UsePreviewControl : bool
Protected Overrides ReadOnly Property UsePreviewControl As Boolean

Property Value

Boolean

Always true.

Remarks

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.
