我正在尝试为
XAML:
GroupStyle
控件模板中的控件设置AutomationProperties.Name
属性,但似乎没有任何效果。我已经在模板中的Expander
上设置了它,即使我只插入一些文本而没有绑定,它也没有显示出来。我还尝试在GroupItem
上放置一个setter,但那也没用。我有点不知所措了。我希望在组项上设置该属性可以解决这个问题。XAML:
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

x:Class="WpfApplication8.MainWindow"

Title="MainWindow"
Width="640"
Height="480">
<Grid x:Name="LayoutRoot">
<ListBox x:Name="lstbx"
Margin="71,45,99,78"
ItemsSource="{Binding ElementName=win,
Path=Samples}">
<ListBox.GroupStyle>
<GroupStyle>
<GroupStyle.ContainerStyle>
<Style TargetType="{x:Type GroupItem}">
<Setter Property="AutomationProperties.Name"
Value="this is a test" />
<Setter Property="KeyboardNavigation.TabNavigation"
Value="Cycle" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type GroupItem}">
<Expander Name="templateLstBxExpander"
AutomationProperties.Name="test test test"

Content="{Binding Path=Name}"

</Expander>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

</GroupStyle>

AutomationProperties
类:提供了一种获取或设置AutomationPeer
元素实例的关联属性值的方法。它不适用于标准 WPF 控件。对于ListBox
,有ListBoxAutomationPeer
类。 - AnjumSKhan<StackPanel IsItemHost="True" />
代替<ItemsPresenter />
,因为我在使用Windows屏幕阅读器时遇到了问题,显然它无法读取<ItemsPresenter>
中的内容。我花了几天时间才弄清楚这个问题。 - IronHide
