Gets or sets an arbitrary string to determine whether a Web Part is authorized to be added to a page.
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
The Web Part infrastructure does not implement any default behavior for the property. However, the property is provided so that you can assign an arbitrary string value to a custom Web Part. This property can be checked by SPWebPartManager during its AuthorizeWebPart event to determine whether the control can be added to the page.
