我有一个 Toolbar，其 ItemSource 是 toolbarItems 的集合，其中包含按钮的位图文本和其他信息，xaml 包含一个 DataTemplate 以将数据绑定到按钮。

我们的应用程序现在需要符合 508 标准，当我运行 Accessible Event Watcher 时，它会将所有工具栏按钮名称列为“未知”。

有人可以告诉我如何为按钮提供有意义的名称吗？

这是适用于此问题的 xaml 部分：

<ToolBar.ItemTemplate>
    <DataTemplate DataType="{x:Type src:toolBarItem}">
          <DataTemplate.Resources>
           <src:toolBarItemConverter x:Key="buttonConverter" />
           <src:booleanToVisibilityConverter x:Key="boolToVisibilityConverter" />
              <src:toolBarButtonFormatConverter x:Key="toolBarFormatDisplayConverter" />
              <src:stringToVisibilityConverter x:Key="stringToVisibilityDisplayConverter" />
    </DataTemplate.Resources>

    <StackPanel Orientation="Horizontal">

        <Border Style="{StaticResource SeparatorStyle}" Visibility="{Binding menuSeparator, Converter={StaticResource boolToVisibilityConverter}}"/>

        <Button x:Name="listButton" Height="{Binding menuHeight, Mode=OneWay}" Width="{Binding menuWidth}" VerticalAlignment="Top" HorizontalAlignment="Center" Visibility="{Binding isActiveButton, Converter={StaticResource boolToVisibilityConverter}}" Tag="{Binding}" 
      ToolTip="{Binding menuTooltip}"  IsEnabled="{Binding isEnabled}"  >
             <UniformGrid VerticalAlignment="Center" HorizontalAlignment="Center" Rows="{Binding menuText,Converter={StaticResource toolBarFormatDisplayConverter}}" >
     <!-- button image -->
     <Image Grid.Row="0"  HorizontalAlignment="Center" VerticalAlignment="Center" Source="{Binding menuImage, Converter={StaticResource buttonConverter}}"/>
     <!-- button name -->
              <Viewbox StretchDirection="DownOnly" HorizontalAlignment="Center" VerticalAlignment="Bottom" Visibility="{Binding menuText, Converter={StaticResource stringToVisibilityDisplayConverter}}" >
               <TextBlock x:Name="buttonName" FontFamily="Segoe UI" Width="{Binding menuWidth}"  FontSize="12" Grid.Row="1" TextAlignment="Center" TextWrapping="Wrap" HorizontalAlignment="Center" VerticalAlignment="Bottom" Text="{Binding menuText}" Foreground="Black" />
     </Viewbox>
    </UniformGrid>
      <!-- </StackPanel> -->
      </Button>          
          </StackPanel>
        </DataTemplate>
   </ToolBar.ItemTemplate>

谢谢，

好的，我们想通了。只需将您的名称绑定到 AutomationProperties.Name

<Button x:Name="listButton" AutomationProperties.Name="{Binding menuText}" 
Height="{Binding menuHeight, Mode=OneWay}" Width="{Binding menuWidth}"  
VerticalAlignment="Top" HorizontalAlignment="Center" 
Visibility="{Binding isActiveButton,  
Converter={StaticResource boolToVisibilityConverter}}" 
Tag="{Binding}" ToolTip="{Binding  menuTooltip}"  IsEnabled="{Binding isEnabled}"  >
