                remarkb:$("#remarkb").combobox('getValue'),
                endDate:$('#endDate').datebox("getValue")
            };
            $("#tablegrid").datagrid( "load" , queryParams );
            $("#tablegrid").datagrid('unselectAll');
            }
    });

解决方案

分页后会自动取消勾选的
不行自己在onLoadSuccess中代码取消

 onLoadSuccess:function(){
  $(this).datagrid('clearChecked')
}

解决方案二：

分页自动取消勾选，如果想换页还能勾选，配置idField就行了
