in AGX 1200 you can add an GP Service to your project. But the input parameters (eg points for the DriveTime Analysis) can only be added interactively by clicking into the map. This way it works fine, but is it possible to load a complete set of input parameters? I want to load local data (xy text r shape file) into such a GP Service? I think it's not possible out-of-the-box. But is it possible to extend AGX via the SDK?
At the next release you will be able to add feature layers whose datasource is either a Layer Package, a File or ArcSDE Geodatabase, or a Shapefile or drag and drop Notes from the Contents window on to the feature list.
