ListBox横向排列

<ListBox.Template>
    <ControlTemplate TargetType="{x:Type ListBox}">
        <Border BorderBrush="#e4e4e4" BorderThickness="1">
            <ScrollViewer HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Auto">
                <WrapPanel Orientation="Horizontal" IsItemsHost="True" ScrollViewer.CanContentScroll="True"/>
            </ScrollViewer>
        </Border>
    </ControlTemplate>
</ListBox.Template>

ListBox ListBoxItem 命令

<Button Content="邀请" Height="28">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Click">
            <i:InvokeCommandAction Command="{Binding Path=DataContext.CommandSendPK,RelativeSource={RelativeSource Mode=FindAncestor,AncestorType=ListBox}}" CommandParameter="{Binding Content, RelativeSource ={RelativeSource AncestorType={x:Type ListBoxItem}}}" />
        </i:EventTrigger>
    </i:Interaction.Triggers>
</Button>

默认显示最后一行

public class ScrollingListBox : ListBox
    {
        protected override void OnItemsChanged(System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
        {
            if (e.NewItems!=null)//此处需要判空
            {
                int newItemCount = e.NewItems.Count;
 
                if (newItemCount > 0)
                    this.ScrollIntoView(e.NewItems[newItemCount - 1]);
 
                base.OnItemsChanged(e);
            }            
        }
    }
