Did you see DataSource.performCustomOperation()?

I've tried to use DSRequest me too but without results... It's very difficult to understand how to use it...

Finally I've passed to server my informations with a custom ListGridRecord:

ListGridRecord rec = new ListGridRecord();
rec.setAttribute("attribute", value);

listGrid.getDataSource().performCustomOperation("test", rec, new DSCallback() {

     @Override
     public void execute(DSResponse response, Object rawData, DSRequest request) {
           // TODO Auto-generated method stub

      }
   }, new DSRequest());
