Public ReadOnly Property IsRestrictedWindow As Boolean

Property Value


true if the form has restrictions; otherwise, false. The default is true.



The IsRestrictedWindow property determines whether the AllWindows permission is granted. This property is set at run time in the form's constructor, and is cached for the lifetime of the form. Windows Forms applications running in partial trust cannot circumvent this check, as the common language runtime ensures that the parent constructor is always called in partial trust.
