我在访问TreeView的每个节点中的控件时遇到了困难。我可以访问树视图节点，但不能访问它们中的控件（扩展器按钮及其消息）。TreeView绑定到ValidationResult数组（代码如下）。
我在这里上传了一张控件的图片：http://s30.postimg.org/j2vszwc01/Results_form.jpg 边框突出显示来自Coded UI Test Builder。它没有看到任何低于TreeViewItem节点级别的内容。
结果查看器控件的定义如下：

验证结果类的定义如下（VerificationError和VerificationWarning每个都包含Description和Message字符串字段）：
[DataContract]
public class ValidationResult
{
[DataMember(Order = 1)]
public VerificationError[] Errors { get; set; }
[DataMember(Order = 2)]
public VerificationWarning[] Warnings { get; set; }
[DataMember(Order = 3)]
public virtual string Description { get; set; }
}
为了访问TreeView中的消息，我需要做什么？
编辑：我尝试以编程方式访问项目并设置每个TreeViewItem的AutomationId，但这两种方法都不起作用。我还创建了一个类似的层次结构，没有数据绑定树视图，我没有访问控件有任何问题。我猜测问题在于数据绑定（http://blogs.msdn.com/b/tapas_sahoos_blog/archive/2011/12/13/verifying-wpf-data-bound-item-controls-in-coded-ui-test-recording-context.aspx），但我不知道如何纠正它。
答案 0 :(得分：1)
您是否尝试过以编程方式访问树？例如：
UITestControl myControl = treeObjectPath;
foreach（myControl.GetChildren（）中的UITestControl x） { 做一点事... }
有时使用Coded UI Test Spy无法捕获对象。
