我可以使用 DataTemplate 作为工具栏按钮并且仍然使名称有意义吗?
我有一个工具栏,其 ItemSource 是工具栏项目的集合,其中包含按钮的位图文本和其他信息,并且 xaml 包含一个将数据绑定到按钮的 DataTemplate。
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一个有意义的名称吗?
以下是适用于此问题的 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,

I have a Toolbar whose ItemSource is a collection of toolbarItems which contain the bitmap text and other info for the button and the xaml includes a DataTemplate to bind the data to the button.
Our app now needs to become 508 compliant and when I run the Accessible Event Watcher it is listing all the toolbar button names as "Unknown".
Can someone tell me how to provide a meaningful name to the buttons?
Here's the portion of xaml applying to this issue:
<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>
Thanks,
Ron

好的,我们想通了。需要简单地将您的名字绑定到 AutomationProperties.Name
OK we figured this out. Need to simply bind your names to the AutomationProperties.Name
