关键是将PreviewMouseRightButtonDown事件设置在正确的位置.你会注意到,即使没有ContextMenu右键单击一个ListViewItem将选择该项目,因此我们需要在每个项目上设置事件,而不是在ListView上.

<ListView>
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListViewItem}">
            <EventSetter Event="PreviewMouseRightButtonDown"
                         Handler="OnListViewItemPreviewMouseRightButtonDown" />
        </Style>
    </ListView.ItemContainerStyle>
    <ListView.ContextMenu>
        <ContextMenu>
            <MenuItem Header="Menu Item">Item 1</MenuItem>
            <MenuItem Header="Menu Item">Item 2</MenuItem>
        </ContextMenu>
    </ListView.ContextMenu>
    <ListViewItem>Item</ListViewItem>
    <ListViewItem>Item</ListViewItem>
    <ListViewItem>Item</ListViewItem>
    <ListViewItem>Item</ListViewItem>
    <ListViewItem>Item</ListViewItem>
    <ListViewItem>Item</ListViewItem>
</ListView>

private void OnListViewItemPreviewMouseRightButtonDown(object sender,MouseButtonEventArgs e)
{
    Trace.WriteLine("Preview MouseRightButtonDown");

    e.Handled = true;
}

由于预览事件为tunneling,因此将阻止RightMouseButtonDown发生在ListViewItems上,从而阻止它们被选中,但不会阻止ListView上的RightMouseButtonDown,因此仍允许ContextMenu打开.
