注意:需要設定ListBox的屬性 ScrollViewer.HorizontalScrollBarVisibility="Disabled"
關鍵程式碼,WPF中有內建的WrapPanel控制元件,在ListBox.ItemsPanel中使用可以讓元素按塊顯示
            <ListBox.ItemsPanel>
                <ItemsPanelTemplate>
                    <WrapPanel/>
                </ItemsPanelTemplate>
            </ListBox.ItemsPanel>
