WPF - 获取没有事件的 DataTemplate

发布于 2024-08-15 18:03:31 字数 724 浏览 3 评论 0原文

我在 Windows.Resources 部分中定义了一个 WPF 数据模板。

我想通过后面的代码访问它（实际上是上面的一个列表框）。我该怎么做？

我无法通过事件获得我想要的东西，因为我想在 BackGroundWorker 的已完成步骤中获取引用。（即没有发送者（即 UI 元素）可以离开那里）。

我怎样才能得到这方面的参考？

我已经尝试过：

myContainingPanel.Template.Find("lstBox", myContainingPanel);

并且（取自此处）：

ContentPresenter contentPresenter = myContainingPanel.FindVisualChild<ContentPresenter>();
DataTemplate template = contentPresenter.ContentTemplate;
return (T) template.FindName(name, contentPresenter);

我会接受一个答案说我应该使用 MVVM，如果有一个很好的例子展示它如何工作（使用后台工作人员完成的事件）。

感谢您的帮助

原文

I have a WPF Data template defined in my Windows.Resources section.

I would like to access this (really a list box on it) via the code behind. How can I do this?

I can't get what I want via an event because I want to get the reference in the completed step of a BackGroundWorker. (Ie no sender (that is a UI element) to go off of there).

How can I get a reference to this?

I have tried:

myContainingPanel.Template.Find("lstBox", myContainingPanel);

and (Taken from here):

ContentPresenter contentPresenter = myContainingPanel.FindVisualChild<ContentPresenter>();
DataTemplate template = contentPresenter.ContentTemplate;
return (T) template.FindName(name, contentPresenter);

I would accept an answer that says I should use MVVM if there is an good example showing how that would work (with a backgroundworker completed event).

Thanks for any help
