推荐答案

首先从这开始...

查看状态：

使用viewstate存储同一页面访问的数据。理想情况下是POSTBACK情况。

例如，想一个报告。当用户选择条件时，附加过滤条件，最后当用户点击提交时，生成报告。在这里，我们可以使用viewstate来保存过滤条件，因为回发了相同的页面。当我们在这里使用session时，过滤条件在会话到期时丢失。



一般来说，对于冗长的报告，禁用viewstate for datastids是一个很好的做法。

First start with this...
View State:
Use viewstate to store data that are accessed by the same page. Ideally a POSTBACK situation.
For example, think of a report. The filter condition is appended as and when the user selects a condition and finally when the user click submit the report is generated. Here we can use viewstate to save the filter condition since the same page is posted back. When we use session here, the filter condition is lost on session expiry.

In general, its a good practice to disable viewstate for datagrids for lengthy reports.
