WPF 中的透明边框以编程方式 [英] Transparent border in WPF programmatically

问题描述

在 XAML 文件的视口上生成一个透明的边框(用于轨迹球事件)很简单:

It's trivial to generate a border (to use for Trackball events) transparent over the viewport in the XAML file:

<Border Name="myElement" Background="Transparent" />

但是我如何在 .cs 中做到这一点?

But how do I do it in the .cs?

Border border = new Border();
**border.Background = (VisualBrush)Colors.Transparent;**
grid.Children.Add(viewport);
grid.Children.Add(border);

这当然行不通.

推荐答案

这是因为您不能仅仅将颜色转换为画笔.改用透明画笔>

This is because you can't just cast a Color to be a Brush. use the Transparent brush instead

border.Background = Brushes.Transparent;
