Is the SF provide the wrapper class for the DevExpress ASPxGrid and Editors Library for ASP.Net ? If not, will it be supported in the future release ?

The DevExpress wrapper does not contain inherited versions of DevExpress's ASP.NET controls, yet, but we are planning to include them in a future version.  We do not inherit/extend the grids since you can bind to them through the BusinessBindingSource.  We are currently developing a WebBusinessBindingSource, but it is not currently included in the release.
