Assembly: Microsoft.SharePoint (in microsoft.sharepoint.dll)
Web site deletion events occur in the following cases:
The Web site is deleted through the user interface.
The folder that contains a Web site is deleted in an application that is compatible with Windows SharePoint Services (such as Microsoft Office SharePoint Designer 2007) through remote procedure call protocol (RPC).
The folder that contains a Web site is deleted through Distributed Authoring and Versioning (DAV).
Web site deletion events occur only for the first Web site in a chain of sites. For example, if a Web site at
http://TopSite/Site, which has the subwebs
TopSite/Site/Subsite2, is deleted in Office SharePoint Designer 2007, only one deletion event occurs, namely, for the
http://TopSite/Site root Web site.
