1. var model = grid.getSelectionModel();
2. model.selectAll();//选择所有行
3. model.selectFirstRow();//选择第一行
4. model.selectLastRow([flag]);//选择最后一行,flag为正的话保持当前已经选中的行数,不填则默认false
5. model.selectNext();//选择下一行
6. model.selectPrevious();//选择上一行
7. model.selectRange(tartRow,ndRow, [Boolean keepExisting] );//选择范围间的行
8. model.selectRow(row);//选择某一行
9. model.selectRows(rows);//选择指定一些行,传递数组如[1,3,5],则分别选择1,3,5行
10. model.clearSelections();//清空所有选择
11. model.deselectRange( startRow, endRow );//取消从startrow到endrow的记录的选择状态
12. model.deselectRow(row);//取消指定行的记录
