This sample is an advanced use of the ProvideDataView event. It demonstrates that it is possible to edit any XML-file using TEdit.NET, even the web.config file of your ASP.NET web sites. Warning: take care when deciding to make an edit-page available for a web.config file on a production server. Also note that the ADO.NET Dataset object strips the web.config file from any comments it may contain. All in all, this sample is best treated as a proof-of-concept only.
