我在ToolBar中使用ToggleButtons，我想在UI自动化测试中使用它们，但是当我检查AutomationElement.Current这些按钮时，它的ClassName属性是Button，而我期望ToggleButton
xaml不是明星向前，所以我在这里提到它：
<ToolBar ItemsSource="{Binding}"/>
对于ItemsSource中的类型，我有一个DataTemplate：
<DataTemplate DataType="{x:Type myViewModelType}">
<ContentPresenter Content="{Binding}" ContentTemplate="{StaticResource MyToolBarElementTemplate}">
<ContentPresenter.Resources>
<Style TargetType="{x:Type ToggleButton}" BasedOn="{StaticResource ThisStyleSetsWidthAndHeight}"/>
</ContentPresenter.Resources>
</ContentPresenter>
</DataTemplate>
样式定义如下：
<Style TargetType="{x:Type ButtonBase}" x:Key="ThisStyleSetsWidthAndHeight">
<Setter Property="styles:AttachedProperties.ContentWidth" Value="32"/>
<Setter Property="styles:AttachedProperties.ContentHeight" Value="32"/>
</Style>
，内容模板如下所示：
<DataTemplate x:Key="MyToolBarElementTemplate" DataType="{x:Type myViewModelType}">
<ToggleButton x:Name="AutomationIdThatIGetOk">
...
</ToggleButton>
</DataTemplate>
我对Automation Framework有点新，我想它与所有这些模板和样式有关，但有没有办法为这个ToggleButton创建正确的AutomationPeer实例？

您的期望是错误的，因为$start = $_REQUEST['iDisplayStart']; // to handle pagination
$length = $_REQUEST['iDisplayLength']; // to handle pagination
$sSearch = $_REQUEST['sSearch']; // for searching
$col = $_REQUEST['iSortCol_0'];
$arr = array(0 => 'id', 1 => 'first_name', 2 => 'last_name', 3 => 'email');
$sort_by = $arr[$col];
$sort_type = $_REQUEST['sSortDir_0'];
$qry = "select id, first_name, last_name, email, position, office from datatables_demo where (first_name LIKE '%".$sSearch."%' or last_name LIKE '%".$sSearch."%' or email LIKE '%".$sSearch."%') ORDER BY ".$sort_by." ".$sort_type." LIMIT ".$start.", ".$length;
$res = mysql_query($qry);
while($row = mysql_fetch_assoc($res))
{
$data[] = $row;
}
$qry = "select count(id) as count from datatables_demo";
$res = mysql_query($qry);
while($row = mysql_fetch_assoc($res))
{
$iTotal = $row['count'];
}
$rec = array(
'iTotalRecords' => $iTotal,
'iTotalDisplayRecords' => $iTotal,
'aaData' => array()
);
$k=0;
if (isset($data) && is_array($data)) {
foreach ($data as $item) {
$rec['aaData'][$k] = array(
0 => $item['id'],
1 => '<span id="'.$item['id'].'" name="first_name" class="editable">'.$item['first_name'].'</span>',
2 => '<span id="'.$item['id'].'" name="last_name" class="editable">'.$item['last_name'].'</span>',
3 => '<span id="'.$item['id'].'" name="email" class="editable">'.$item['email'].'</span>',
4 => '<span id="'.$item['id'].'" name="position" class="editable">'.$item['position'].'</span>',
5 => '<span id="'.$item['id'].'" name="office" class="editable">'.$item['office'].'</span>'
);
$k++;
}
}
echo json_encode($rec);
类实际上从其ToggleButtonAutomationPeer方法返回string“按钮”：https://referencesource.microsoft.com/#PresentationFramework/src/Framework/System/Windows/Automation/Peers/ToggleButtonAutomationPeer.cs,a58abe77888c16cd
所以你得到了正确的实例。
