ASP.NET单选按钮的名称搞乱（组名） [英] ASP.NET RadioButton messing with the name (groupname)

问题描述

我有一个模板化控件（中继）上市的一些文字和其他标记。每个项目具有与其相关联的单选按钮，从而有可能为用户选择由中继创建的项目之一。

I got a templated control (a repeater) listing some text and other markup. Each item has a radiobutton associated with it, making it possible for the user to select ONE of the items created by the repeater.

中继器写入单选设置与ASP.NET的默认命名约定使每一个单选按钮一个完整的'小组'生成的ID和名称。这意味着所有单选按钮是独立于对方，这再次不幸意味着我可以在同一时间选择所有单选按钮。该单选按钮，用来设置一个共同的名字聪明属性'组名'，使他们获得组合在一起，因此应该依赖（所以我只能选择一次）。问题是 - 这并不工作 - 中继确保id和由此而得名（控制组）是不同的。

The repeater writes the radiobutton setting its id and name generated with the default ASP.NET naming convention making each radiobutton a full 'group'. This means all radiobuttons are independent on each other, which again unfortunately means I can select all radiobuttons at the same time. The radiobutton has the clever attribute 'groupname' used to set a common name, so they get grouped together and thus should be dependant (so I can only select one at a time). The problem is - this doesn't work - the repeater makes sure the id and thus the name (which controls the grouping) are different.

由于我使用一个中继器（可能是一个列表视图或任何其他模板化数据绑定控件），我不能使用单选按钮列表。那么，这是否离开我？

Since I use a repeater (could have been a listview or any other templated databound control) I can't use the RadioButtonList. So where does that leave me?

我知道我已经有这个问题，解决它。我知道，几乎每一个ASP.NET程序员一定也曾经有过，所以我为什么不能谷歌和找到一个坚实的解决问题的办法？我碰到的解决方案来执行由JavaScript分组（丑陋！），甚至处理单选按钮非服务器控件，强迫我做了一个的Request.Form [名称] 读取状态。我也试图与覆盖上的 preRender 事件中的name属性实验 - 不幸的是，拥有的页面和母版再次重写这个名称，以反映全ID /名称，所以我结束与相同的错误的结果。

I know I've had this problem before and solved it. I know almost every ASP.NET programmer must have had it too, so why can't I google and find a solid solution to the problem? I came across solutions to enforce the grouping by JavaScript (ugly!) or even to handle the radiobuttons as non-server controls, forcing me to do a Request.Form[name] to read the status. I also tried experimenting with overriding the name attribute on the PreRender event - unfortunately the owning page and masterpage again overrides this name to reflect the full id/name, so I end up with the same wrong result.

如果你没有比我张贴更好的解决方案，你仍然非常欢迎发表您的想法 - 至少我要知道，我的朋友杰克'是正确的关于如何搞砸了ASP.NET有时;）

If you have no better solution than what I posted, you are still very welcome to post your thoughts - at least I'll know that my friend 'jack' is right about how messed up ASP.NET is sometimes ;)

该ID识别码的确实是一个不幸的后果。我采取将创建一个 - 或采摘的许多可用的一个 - 在客户端上添加了同名支持自定义控制

Indeed an unfortunate consequence of the id mangling. My take would be creating a - or picking one of the many available - custom control that adds support for same name on the client.
