Windows 10 UWP app c＃ - 禁用组合框中的鼠标滚轮

Question

如何在组合框控制中禁用鼠标滚轮？

<ComboBox x:Name="ListDates" SelectedValuePath="Tag" Width="185" Background="#FFFFCC00" BorderThickness="1" Margin="12,8,0,0"/>

Answer 1

If you must do that, it's pretty simple - just disable vertical scrolling on the inner ScrollViewer.

<ComboBox x:Name="ListDates" 
          ScrollViewer.VerticalScrollMode="Disabled" 

Answer 2

这个解决方案很冗长但有效。创建你的组合框类并用空处理程序覆盖OnPointerWheelChanged。

public class ComboBoxNoWheel: ComboBox
{
    protected override void OnPointerWheelChanged(PointerRoutedEventArgs e)
    {

    }
}

您可以添加e.handled = true，但这与我的测试没有任何区别。组合框打开时滚动效果很好。
