MouseLeftButtonDown 没有被解雇 [英] MouseLeftButtonDown is not getting fired

问题描述

我有一个从 UserControl 类派生的 WPF 用户控件.MouseLeftButtonDown 根本没有因为控制而被触发.我添加了事件处理程序，并尝试如下.我想它是在其他地方处理的，如何调试并找到它在哪里得到处理.. 任何帮助表示赞赏！

protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e)
{
    base.OnMouseLeftButtonDown(e); 
} 

推荐答案

您是否将 UserControl 的背景设置为某些内容?如果没有，请尝试将其设置为背景=透明"，看看是否有效.如果它不起作用，您能否发布 UserControl 的 XAML 及其用法?

Did you have the Background of the UserControl set to something? If not, try setting it to "Background=Transparent" and see if that works. If it doesn't work, can you post the XAML for your UserControl, as well as the XAML for its usage?
