我的pivotPageViewModel
public class PivotPageViewModel : Conductor<IScreen>.Collection.OneActive
{
private readonly PivotItem1PageViewModel item1;
private readonly PivotItem2PageViewModel item2;
public PivotPageViewModel(PivotItem1PageViewModel item1, PivotItem2PageViewModel item2)
{
this.item1 = item1;
this.item2 = item2;
}
protected override void OnInitialize()
{
base.OnInitialize();
Items.Add(item1);
Items.Add(item2);
ActivateItem(item1);
}
}PivotItem1
public class PivotItem1PageViewModel : Screen
{
public String DisplayName { get; set; }
public List<String> Item{ get; set; }
public PivotItem1PageViewModel (INavigationService navigationService)
: base(navigationService)
{
DisplayName = "Name";
Item= new List<String>();
Item.Add("one");
Item.Add("two");
Item.Add("three");
Item.Add("four");
}
public void SelectedItemChanged(String select)
{
Debug.WriteLine("HElllo!!! " + select);
}
}XAML
<ListBox x:Name="Secretariat" Foreground="Black"
FontFamily="{StaticResource PhoneFontFamilyLight}"
FontSize="50" Margin="10,0,-14,0"
cal:Message.Attach="[Event SelectionChanged] = [Action SelectedItemChanged($this)]">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>`当我使用枢轴时,我的SelectedItemChanged不起作用,但是当我使用正常的页面时,SelectedItemChanged通常能工作。

根据Caliburn.Micro文档:
$this -将操作附加到的实际ui元素
因此,您的select参数很可能不是字符串而是ListBox。你对“找不到的行动”有什么例外吗?
