should first check page if it is postback, then .... -alittleman(凡人); 2007-5-11 (#3669174@0)

no, this actually has been reported to microsoft previously -sowen(sowen); 2007-5-11 {192} (#3669478@0)

I *guess* the server-side ReadOnly property kind of persists the value in viewstates and doesn't let it refresh from postback, while Attribute["readonly"] just simply passes to client as HTML attribute setting. -tonixlaw(bigt); 2007-5-25 (#3699824@0)

试一下: 把textbox的readonly改为disabled. 这样看上去readonly但你可以用javascript操作它. 我最近这样的事做了不少.我用是ASP,还没到.net. 但HTML,javascript的东西都是一样的. 有什么问题可以交流. -dabiziabu(大鼻子阿布); 2007-5-15 (#3678514@0)

其实我上面找到的那个 ms lab 的link里面已经解释了这个issue，那里有好几个work around，你说的可以是一种，不过disable会改变textbox feel，所以我用了另外一种solution -sowen(sowen); 2007-5-16 (#3678757@0)

现在的web develper都不需要懂HTML,Javascript就可以干活了，微软真是有本事。 -dzhu(Daniel); 2007-5-25 (#3699663@0)

what the hell do u mean? when I was working on web development, u might not start coding yet! on the other hand, it's apparently not a javascript issue, it's a server-side behavior. -sowen(sowen); 2007-5-25 (#3699685@0)

我不太写Code了，我只是想说aspx里最好只有一行code，C# 里别有if(Page.ispostback)，不然只是入门级.Net web developer -dzhu(Daniel); 2007-5-25 (#3699773@0)

u totally lost me, I guess u have no idea what I was discussingReadOnly is a server-side property, in ASP.NET 2.0, MS changed the behavior to handle readonly textbox. That's why we have to use client-side script to make a readonly textbox to workaround.

I don't know what the heck u want to say now -sowen(sowen); 2007-5-25 {241} (#3699819@0)
Would you detail your seond part of the comments? Why is that? -tonixlaw(bigt); 2007-5-25 (#3699834@0)
我也觉的我没说清楚，不过要说清因该要很多篇幅，简单的说说吧，请进就提几个问题当作启发吧：

1. viewState
这个东西在稍微大点的项目里因该都会被明文禁止，在web.config里关了后，尝试完成以前postback self的功能，这样是不是不用那么在乎server behavior

2. 假设楼主做的页面是10000个这样的button ,link ，也这样写吗

3. 要是这个项目被突然要求改为PHP了怎么办 -dzhu(Daniel); 2007-5-25 {287} (#3699943@0)

interesting, I am working on a framework, which is a control that will be used by over 10000 pages, u don't need to worry about that. for ViewState point -sowen(sowen); 2007-5-25 {800} (#3699993@0)

i don't get it - why "(viewstate)这个东西在稍微大点的项目里因该都会被明文禁止"? under what kind of specific circumstances? -tonixlaw(bigt); 2007-5-26 (#3701109@0)

Viewstate has lots of advantages and as well as disadvantages。 -dzhu(Daniel); 2007-5-27 {1333} (#3703089@0)

如果你一定要那么 picky，viewstate 的坏处我闭着眼都能讲出一大堆，ASP.NET 2.0 或者 WFX 的坏处也是随手可来问题是，所有的 framework 目的都是在于 productivity ，都是靠牺牲 performance 来提高 maintenance， scalability 和 extensibility，我很怀疑你是否真的是一个所谓“大师级”的web app developer or consultant, whatever you name yourself，java 的 framework 也一样有这样的毛病， RUBY 又何尝不是？

所以，如果一个公司决定要用一个技术，是 compromise 而不是 refuse to use its feature and then tell urself u r doing the correct thing -sowen(sowen); 2007-5-28 {421} (#3704889@0)
can't agree with you -tonixlaw(bigt); 2007-5-29 {2062} (#3707543@0)

exactly, I really doubt if that guy can call himself understand viewstate or not如果一个 datagrid is sorted，然后 page，结果还是 sorted 的

在新的 asp.net 里，就是通过 viewstate 来完成的，并不是象以前那样重新 query 然后 position

至于 viewstate size，有很多方法 avoid，包括 serverside viewstate 等等 -sowen(sowen); 2007-5-29 {225} (#3707559@0)

viewstate很灵活，说禁止viewstate,那是不懂。微软在网页放的这些垃圾，是asp.net的基础，没有它们，asp.net就没有那么强大，易用了。 -googlebot(bot); 2007-5-27 (#3703535@0)

正是如此。下一步，将消灭desktop application和web (client) application 的区别。 -alittleman(凡人); 2007-5-25 (#3700074@0)
HTML， JS还是要知道一点的，可以起到画龙点睛的效果 -sunnyside(sunnyside); 2007-5-26 (#3701552@0)

That is almost the same problem I had recently.. its a bug on DotNet 2.0. If you use DotNet 1.x. "readonly" textbox on postback works perfectly. There is way to work around it. -sunday8(sunday8); 2007-5-25 (#3699998@0)

yes yes, already fixed it after I post it a short while later, I have the same URL in the above reply. thanks though. -sowen(sowen); 2007-5-25 (#3700025@0)

other than your indicated workaround, i think if you use a (server-side) hidden field to actually store user's input and be posted back to server, that will work too. -tonixlaw(bigt); 2007-5-26 (#3701111@0)
