如何去掉ListView默认的选中效果

Answer 1

而且它不仅会选中，还会触发一次SelectionChanged事件，当然，我们要让ListView可点击，一种流行的做法确实是用SelectionChanged事件，就像这样：
private void StationsList_OnSelectionChanged(object sender, SelectionChangedEventArgs e)
{
var station = StationsList.SelectedItem as Station;
if (null != station)
{
SelectedStationChanged?.Invoke(this, station);
}

StationsList.SelectedItem = null;
}

但是因为数据绑定之后会被默认选中一项，所以这个事件被直接触发了，用户就会直接进入Item的子页面，ListView会一闪而过，为此我还写过workround：
private void StationSearchResultListControl_OnSelectedStationChanged(object sender, Station station)
{
if (selectedAllStationListCount > 0)
{
if (null != station)
{
Frame.Navigate(typeof(StationDetail), station);
}
}

selectedAllStationListCount++;
}

// Work around, listview seems got default selected value.
private int selectedAllStationListCount;

结果今天发现其实ListView的默认选中效果是可以去掉的，只要把SelectionMode设置为None:
SelectionMode="None"

现在就不会有默认选中项了：

然后把点击的事件从SelectionChanged换成ItemClick，而且一定记得要把IsItemClickEnabled打开：
<ListView x:Name="StationsList"
ItemsSource="{Binding Source={StaticResource GroupedStations}}"
Margin="-10,0,0,0"
SelectionMode="None"
HorizontalContentAlignment="Stretch"
ItemClick="StationsList_OnItemClick"
IsItemClickEnabled="True">

这样后台代码就可以用e.ClickedItem直接获得当前被点击的对象：
private void StationsList_OnItemClick(object sender, ItemClickEventArgs e)
{
var station = e.ClickedItem as Station;
if (null != station)
{
SelectedStationChanged?.Invoke(this, station);
}

StationsList.SelectedItem = null;
}
