How can I find a style trigger-embedded element by name in WPF?

由 依然范特西╮ 提交于 2019-12-11 03:04:34
问题 First, the heart of the question: If an element is assigned as the Content of a ContentControl via a style trigger, I can't seem to find it by name.

When that bug is null, it is a search form, when it is non-null, it is a simple viewer for properties of that bug. The XAML then look something like: <ContentControl DataContext="...">

My initial hope was that the sub classed DataTemplateSelector would be called, but it isn't. Then I tried adding an entry in the Resource Dictionary of the calling assembly with the same key but the sub classed selector, but that doesn't get it done either. Is there a way

问题 Im trying to create some chart images without ever displaying those charts on the screen. I'v been at this for quite a while and tried a lot of different things but nothing seems to work. The code works perfectly if I display the chart in a window first, but if I don't display it in a window, the bitmap is just white with a black border (no idea why). I have tried adding the chart to a border before rendering and giving the border a green borderBrush. In the bitmap, I see the green
