请问是不是用
ViewState[] 的方法来对上面的变量赋值可以减少变量多次赋值现在我想问的是ViewState[] 会占内存吗?在B/S项目中用来代替 这些变量合适吗?
性能怎么样?谢谢

这个是没错。但是我搜索完后,剩下的数据还是要分页的。
我想问的是变量多次赋值这样写太麻烦了。
你们都是用 ViewState[] 这边方法在页面上给变量赋值吗?
只要写一次即可吗?
请问是不是用
ViewState[] 的方法来对上面的变量赋值可以减少变量多次赋值现在我想问的是
ViewState[StrDateStart ]
ViewState[StrDateEnd]
ViewState[StrDateStart_m]
ViewState[StrDateEnd_m]
ViewState[StrItemCode] 会占内存吗?在B/S项目中用来代替 这些变量合适吗?
性能怎么样?谢谢。
