Question

不是有sender吗
把它转成button就好了

Answer 1

Button btn=sender as Button;
然后获取btn.Name

Answer 2

Button btn = ((e.Source as MenuItem).Parent as ContextMenu).PlacementTarget as Button;
 结贴吧。

Answer 3

private void BtnMenuItem_Click(object sender, RoutedEventArgs e)
{
    ContextMenu cm = (ContextMenu)ContextMenu.ItemsControlFromItemContainer((MenuItem)e.OriginalSource);
    UIElement placementTarget = cm.PlacementTarget;
    Button btn = placementTarget as Button;
}

Answer 4

你的却是是正解？但我在ContextMenu用绑定后MenuItem的Parent为null，你试试看是不？     <Button>
                                <Button.ContextMenu>
                                    <ContextMenu>
                                        <ContextMenu.ItemContainerStyle>
                                            <Style TargetType="{x:Type MenuItem}">
                                                <Setter Property="Header" Value="{Binding ItemHeader}"/>
                                                <EventSetter Event="MenuItem.Click" Handler="Item_Click"/>
                                            </Style>
                                        </ContextMenu.ItemContainerStyle>
                                    </ContextMenu>
                                </Button.ContextMenu>
                                <Image Source="images/tools.tif" Stretch="Fill"/>
                            </Button>
  private void Item_Click(object sender, RoutedEventArgs e)
        {
//........
}
