我在我的UWP应用程序中使用Telerik RadListView控件。我想删除RadlistView提供的默认选择背景，它在image here中以绿色显示
答案
Telerik for UWP现在是开源的。你可以从GitHub看到它的所有代码：https://github.com/telerik/UI-For-UWP
对于您的问题，如果您在visual studio中调试项目并检查其可视化树，您会看到它实际上是一个名为“CheckBox”的Grid控件。
因此，我们需要做的是找到RadListViewItem的样式，并在选中时更改'CheckBackground [Path]'填充颜色。
然后，RadListViewItem的样式也可以在github：https://github.com/telerik/UI-For-UWP/blob/master/Controls/DataControls/DataControls.UWP/Themes/Generic.xaml#L705上找到
您可以复制它并将其应用于您自己的项目。为了满足您的要求，您只需要更改此样式中的“已选择”视觉状态。
我做了一个代码示例供您参考：
