ASP.Net的FindControl不工作 - 为什么？ [英] ASP.Net FindControl is not working - How come?

问题描述

我已经使用的FindControl 在过去之前，.NET 2.0 / 3.0。这似乎是现在，由于某种原因，该ID是我的控制得到一个时髦的命名分配。例如，我分配一个ID为cbSelect一个复选框，但的FindControl没有找到它。当我看到它被分配在HTML ctl00_bodyPlaceHolder_ctl02_cbSelect 。

I have used FindControl in the past, prior to .NET 2.0/3.0. It seems like now, for some reason, the ID's of my controls get a funky named assigned. For example I assigned an id "cbSelect" to a checkbox, but FindControl does not find it. When I view the HTML it was assigned ctl00_bodyPlaceHolder_ctl02_cbSelect.

我还没有发现的FindControl的一个例子，提到。其实每个人似乎都只是用找到像正常对照组。

I have not found one example of FindControl that mentions that. In fact everyone seems to just use find control like normal.

所以，我做错了什么？没有净变化？任何人都可以摆脱一些轻到这对我来说，这是很无奈！

So, am I doing something wrong? Did .Net change? Can anyone shed some light onto this for me, it is really frustrating!

推荐答案

您可能正在使用一个母版或用户控件（ASCX），这是对客户端ID改变的原因。想象一下，你在用相同的ID为一体，在页面的母版页的控制。这会造成冲突。该ID的变化，确保所有客户端ID属性页上是唯一的。

You are probably using a MasterPage or user controls (ascx) and this is the reason the for client ids change. Imagine you have a control in the master page with the same id as one in the page. This would result in clashes. The id changes ensures all ClientID properties are unique on a page.

与MasterPages工作时的FindControl需要一些特别的注意。看一看 ASP.NET 2.0 MasterPages和的FindControl（）。该工程的FindControl一个命名容器。该MastePage和页面是不同的命名容器。

FindControl needs some special attention when working with MasterPages. Have a look at ASP.NET 2.0 MasterPages and FindControl(). The FindControl works inside a naming container. The MastePage and the page are different naming containers.
