smartclient listgrid 数据之间的拖拽
从listgrid1将信息拖拽到listgrid2内，方便灵活实现数据的传递
注意事项：
Listgrid1中增加属性
canDragRecordsOut: true,
dragDataAction: "copy",
listgrid2 中增加属性
canAcceptDroppedRecords: true,
canRemoveRecords: true,
preventDuplicates: true,
leaveScrollbarGap: false,
注意：
Datasource1中的pk在datasource2中做fk，配置这一点时，当拖拽数据时出发add请求，并将所拖拽的数据传递给后台处理
（也可以从listgrid1中选中一行数据，单击蓝色图标触发：projectList.transferSelectedData(employeesList)事件）
