什么更好，隐藏的表单字段或viewstate？ [英] What's better, a hidden form field or viewstate?

问题描述

你好，


我有一个页面在查询字符串中传递了一个ID。然后它使用

这个ID从数据库中提取信息并在

页面上填充控件。当页面回发后，查询字符串将不再是

，所以我需要一些方法来存储ID。


什么这是最好的方法吗？显而易见的想法是一个隐藏的形式

字段，但似乎没有一个网页控件。我只是

使用普通的HTML控件吗？


另一个想法是把ID放在viewstate中，但这个

听起来有点超过顶部，而且它有可能从视图状态下降价值

。


我不是想要将它存储在Session中，因为它超时。


有何评论？ TIA

Hello,

I have a page that gets passed an ID in the query string. It then uses
this ID to pull info out of a database and populate controls on the
page. When the page is posted back, the query string is not going to be
there any more, so I need some way of storing the ID.

What''s the best way of doing this? The obvious thought is a hidden form
field, but there doesn''t seem to be a web control for this. Do I just
use an ordinary HTML control?

The other thought I had was to put the ID in the viewstate, but this
sounds a bit over the top, plus it has the risk that the value might be
dropped form the viewstate.

I don''t want to store it in the Session as that times out.

Any comments? TIA

推荐答案

如果您需要在服务器和

客户端之间传递值，则使用隐藏的表单字段。如果只需要在回发之间保持一个值，请使用

viewstate。

A hidden form field is used if you need to pass values between server and
client. If all you need is just to persist a value between postbacks, use
viewstate.

最好的方法是什么这个？显而易见的想法是一个隐藏的形式领域，但似乎没有一个网络控制。我只是使用普通的HTML控件吗？

另一个想法是将ID放在viewstate中，但这听起来有点过头，加上它可能会从视图状态中删除该值。

我不想将其存储在会话中，因为它会超时。

Viewstate也放在一个隐藏的表单字段中，所以没有太大区别

除了viewstate更容易。


如果你让我知道还有其他问题..

Viewstate is also put in a hidden form field so there is no big difference
other than that viewstate is easier.

Let me know if you have any more questions..

我同意以前的帖子，viewstate是最简单的。

如果你确实想要使用隐藏字段动态值你可以在你的表单中添加一个

''Literal''web控件并在页面中设置它的文本属性

加载到：


"< input type =''hidden''id =''hiddenField''value =''" + ID +"''>" ;;


"到******************** @ pandora。是"写道：

I agree with the previous posts, viewstate is easiest.
If you did want to use a hidden field with a dynamic value you can add a
''Literal'' web control to your form and set it''s text property during the Page
Load to:

"<input type=''hidden'' id=''hiddenField'' value=''" + ID + "''>";
