坚持在回传C＃对象 [英] Persist c# objects across postbacks

问题描述

我有一个具有C＃code-背后做一些东西在Page_Load（）方法（如查询数据库，并提出一些其他调用来填充数据对象）一个asp.net页面。然后，我在页面上显示该数据。这一切工作正常。我设置了一对夫妇回传，使被点击列表框的值时，面板控制充满了相应的对象的数据的其余部分。我想回发是这样做的正确的方式，但是这会导致（整个班级？）重新调用，从而重新初始化我的对象，破坏我想保留的数据。

I've got an asp.net page that has c# code-behind that does some stuff in the Page_Load() method (like query a database and make a few other calls to populate objects with data). I then display this data on the page. This all works fine. I set up a couple of postbacks so that when a value in a listbox is clicked, a panel control is filled with the rest of the corresponding object's data. I thought postbacks were the right way to do this, but this causes the (entire class?) to be re-called, which re-initializes my objects and destroys the data I want to keep.

将某种形式的局部回传的解决这个问题，还是有实现我想要做的更好的办法？

Will some form of partial-postback solve this problem, or is there a better way to implement what I'm trying to do?

我不希望每次回传被调用时重新填充的对象，因为这需要一个数据库查询，我想避免重新查询每一次的东西被点击...

I don't want to re-populate the objects every time a postback is called, as that takes a database query, and I want to avoid re-querying every time something is clicked...

我发现关于坚持JavaScript对象的许多问题，但没有真正似乎解决这​​个问题。我使用.NET 4.0

I've found many questions regarding persisting Javascript objects, but nothing that really seems to address this. I'm using .Net 4.0
