Hello Larkin Young,
The TelerikSPRadGrid Web Part features a structure-and-data
designer that makes it possible to display and manipulate data coming from tables lying on
SharePoint lists either in a flat or hierarchical form. (see
Hierarchical Data for more information). So there should be no issues with binding RadGrid to SP list using the designer. All features you mentioned will work properly.
Greetings,
Maria Ilieva
