使用如下代碼,當TextBlock文本過長,引發Button的顯示位置在可見區域之外:spa
1 <Window x:Class="WpfApplication11.MainWindow" 2 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 3 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 4 Title="MainWindow" Height="200" Width="200"> 5 6 <DockPanel> 7 <TextBlock Text="edrftgyhjnjmkfvtygbhunjiuhibygtvhnjukiytgvfbyhnj" TextTrimming="CharacterEllipsis"/> 8 <Button Content="Button" Width="100" DockPanel.Dock="Right"/> 9 </DockPanel> 10 </Window>
