You can add below piece of code in Controller(You need to Import your custom VORowImpl in CO)

 or Best Practice is to add method in AM and call AM method from Controller.

      if (pageContext.getParameter("DelBtn") != null)
        {
            System.out.println("Proceed Delete");
            OAViewObject vo = (OAViewObject)am.findViewObject("XxFileBlobsVO1");

            Row row[] = vo.getAllRowsInRange();

            for (int i=0;i<row.length;i++)
              {
              XxFileBlobsVORowImpl rowi = (XxFileBlobsVORowImpl)row[i];
                if (rowi.getSelToDel()!= null && rowi.getSelToDel().equals("Y"))
                {
                  oracle.jbo.domain.Number vFileId = (oracle.jbo.domain.Number)rowi.getFileId();
                  rowi.remove();   // Here you can call updates if reqd
                  System.out.println("Selected To Delete File Id "+vFileId);
                }
              }
             
            am.invokeMethod("apply");

       }
