WPF ComboBox 展开之后,如何实现鼠标移出后自动收起ComboBox Item? RRS feed

  • 问题

  • 尝试直接设置ComboBox的MouseLeave 事件,发现鼠标移出时并不触发;

    然后在别的控件的Mouse Enter中设置相关属性,发现也不触发。


    那么,如何才能实现在鼠标移出后自动收起ComboBox Item?

  • 你好,

    可以使用 IsMouseDirectlyOverChanged 来实现。

    private void ComboBox_IsMouseDirectlyOverChanged(object sender, DependencyPropertyChangedEventArgs e)
                if (combo1.IsDropDownOpen == true)
                    combo1.IsDropDownOpen = false;
