Tab键顺序不适用于xaml中的TextBlock。我已将标签索引属性分配给TextBlock，但关注<Canvas x:Name="cvs_links"
Height="19" Width="224"
HorizontalAlignment="Left"
KeyboardNavigation.IsTabStop="True"
KeyboardNavigation.TabNavigation="Local">
<TextBlock x:Name="Link_selectnone"
IsEnabled="{Binding Path=HasDevices}"
Height="19" Width="98.734"
TextWrapping="Wrap"
FontSize="12"
Foreground="#FF6987BF"
MouseEnter="Link_selectall_MouseEnter"
MouseLeave="Link_selectall_MouseLeave"
MouseLeftButtonDown="Link_selectnone_MouseLeftButtonDown"
Canvas.Left="0" Canvas.Top="0">
<Run Text="{x:Static local:Resources.DISCOVERYCTRL_SELECTNONE}"
TextDecorations="Underline"/>
<LineBreak/>
<Run TextDecorations="Underline"/>
<LineBreak/>
<Run TextDecorations="Underline"
KeyboardNavigation.IsTabStop="True"
KeyboardNavigation.TabIndex="1"
Focusable="True"
IsEnabled="True"/>
</TextBlock>
</Canvas>
无法按下TAB按钮。
