使用在 Caliburn Micro网站我修改了您的XAML,使其看起来像这样:
Using the information I found on the Caliburn Micro site I modified your XAML to look like this:
<Grid Background="White" HorizontalAlignment="Stretch" Height="200" Name="GridLayout">
<ListBox x:Name="ListBoxItems">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid Tag="{Binding DataContext, ElementName=GridLayout}">
<Grid.ContextMenu>
<ContextMenu Name="cm" cal:Action.TargetWithoutContext="{Binding Path=PlacementTarget.Tag, RelativeSource={RelativeSource Self}}">
<MenuItem Header="Open"
cal:Message.Attach="Open($dataContext)">
</MenuItem>
</ContextMenu>
</Grid.ContextMenu>
<TextBlock VerticalAlignment="Center" >
.. text..
</TextBlock>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
我的视图模型:
public List<string> ListBoxItems { get; set; }
public ShellViewModel()
{
ListBoxItems = new List<string> {"One", "Two", "Three"};
}
public void Open(object source)
{
MessageBox.Show((string) source);
}
已使用列表框中的相应字符串成功调用了Open。
Open was successfully called with the appropriate strings from the list box.
