Property Value

Type: System.Boolean

true if the opacity of the form can be changed; otherwise, false.

This property is automatically set to true if the Opacity is changed. When the opacity of a form is set using the Opacity property, the form will layer objects on the form. If you set the AllowTransparency property to false the form will not be in layered mode which will improve the display performance of the form.
