WPF-获取没有事件的DataTemplate [英] WPF - Get DataTemplate without an event

问题描述

我在Windows.Resources部分中定义了WPF数据模板。

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

我想通过后面的代码访问它（实际上是列表框） 。我该怎么办？

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

我无法通过事件获得想要的东西，因为我想在BackGroundWorker的完整步骤中获得引用。 （即没有发送者（即UI元素）可以离开那里。）

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).

如何获得对此的引用？

我尝试过：

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

和（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，即如果有一个很好的例子说明应该如何使用MVVM，我应该使用MVVM。

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).

感谢您的帮助

推荐答案

FrameworkElement.FindResource（）应该管用。从viewmodel查找数据模板对我来说似乎不合适。您想做什么？

FrameworkElement.FindResource() should work. Finding data templates from viewmodel doesn't seem right to me. What are you trying to do?
