If I start with
如果我开始
Page.Controls
Then recursively call all the children control.Controls, will the guarantee that I find all the controls that exist on a given page. Are there any time that orphaned controls can exist, or any other controls that will not show up when iterating through the page's controls in this way?
然后递归调用所有子控件。控件,将保证我找到给定页面上存在的所有控件。是否有任何时候可以存在孤立控件,或者以这种方式迭代页面控件时不会显示的任何其他控件?
Even if this is correct is there a better way of finding all of a page's controls?
即使这是正确的,有更好的方法来查找页面的所有控件吗?
3 个解决方案
#1
It will find all the controls that exist when you ask. There's nothing to say that more controls won't be added later, after DataBinding, for instance.
当你提问时,它会找到所有存在的控件。没有什么可说的,例如,在DataBinding之后,以后不会添加更多的控件。
Maybe you want to check in the OnPreRenderComplete method?
也许你想检查一下OnPreRenderComplete方法?
#2
Obviously, this will give you controls with runat=server specified. It won't give plain old HTML controls.
显然,这将为您提供指定runat = server的控件。它不会提供普通的旧HTML控件。
#3
I use ControlFinder helper for access to all my children controls. Get it and adapt to your code.
我使用ControlFinder帮助程序访问我所有的子控件。获取它并适应您的代码。
