Me parece que si lograste la forma de cargar la grilla con un servicio (me imagino que un HttpRequest), entonces el problema está resuelto, ya que lograste la comunicación con el servidor. Para guardar los datos, tenés que implementar un servicio parecido, solamente que los parámetros que le pasás te sirven para guardarlo, y el servicio no te devolvería dato alguno (o si). Para agregados/modificados, sólo basta recorrer el dataset asociado a la grilla, obtener los records modificados (la grilla tiene un método que te los proveed) y chequear si el Record ha sido modificado/ agregado. Creo que convendría llamar al servicio que modifica por cada uno de los records. Sería de ayuda si postearas parte del codigo (el que te funciona para cargar y el que intentaste para guardar).
El lunes lo veo y te aviso. Un abrazo. Leo <!--ENGLISH--> I think that if you could load the grid with a services (I presume a HttpRequest), the problem should be that, because you made the connection with the server. To save data, you should do the same and the parameters that you pass are the data you want to save. To detect the records on your grid's dataset which have been modified/ added, the grid has a method that gives you those records. Then you could call the service to save data for each modified/added record. If you could post some code, it will help us to help you.
