我有ListBox
这样:
<ListBox DataContext="{Binding UpdateSourceTrigger=PropertyChanged}"
ItemsSource="{Binding UpdateSourceTrigger=PropertyChanged}"
ListBoxItem.Selected="ListBoxItem_Selected">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<DockPanel>
<Label Content="{Binding Path=Attribute[rdv].Value, UpdateSourceTrigger=PropertyChanged}" />
</DockPanel>
<DockPanel>
<Label Content="{Binding Path=Attribute[type].Value, UpdateSourceTrigger=PropertyChanged}" />
<Label Content="{Binding Path=Element[ville].Attribute[saisie].Value, UpdateSourceTrigger=PropertyChanged}" />
<Label Content=":" />
<Label Content="{Binding Path=Element[adresse].Attribute[saisie].Value, UpdateSourceTrigger=PropertyChanged}" />
</DockPanel>
<Separator />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
当选择ListeBoxItem
时,我想要举办活动。
正如您所看到的,我尝试使用ListBoxItem.Selected="ListBoxItem_Selected"
,但它不起作用。
你有什么想法吗?
提前坦克!

您的处理程序不会被调用,因为ListBox已经处理了Selected事件。您应该在ListBox中处理SelectionChanged事件:
<ListBox DataContext="{Binding UpdateSourceTrigger=PropertyChanged}"
ItemsSource="{Binding UpdateSourceTrigger=PropertyChanged}"
SelectionChanged="ListBox_SelectionChanged">
或者,您可以使用ItemContainerStyle将处理程序附加到每个ListBoxItem:
<ListBox DataContext="{Binding UpdateSourceTrigger=PropertyChanged}"
ItemsSource="{Binding UpdateSourceTrigger=PropertyChanged}">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<EventSetter Event="Selected" Handler="ListBoxItem_Selected"/>
</Style>
</ListBox.ItemContainerStyle>
