在 Powershell 和 WPF 中使用 FindName
Using FindName in Powershell a WPF
我需要一些有关 Powershell 和 WPF 的帮助。
我正在修改某人使用 WPF 和 powershell 制作的加载项。所以我不是 100% 确定 xaml 结构是如何布局的。我想做的是修改运行时生成的某个元素的Text 属性。我用的是Snoop2.8.0，找到了我要修改的元素，名字是属性"FreeTextBox"。我打算使用 FindName 方法获取元素，但是，FindName 方法 returns 什么都没有。
我在一些 post 中读到，有一个单独的东西叫做 contentPresenter，其中存储了这些运行时元素，我需要引用它才能进入我的文本框，但是，我没有知道怎么做。如果有人能指出正确的方向，我将不胜感激。
问候

从第二段代码的最后一行可以看出，我正在尝试使用 findname 来获取从主应用程序创建的 FreeTextBox。不幸的是，我没有创建文本框的代码，因为这是一个从主应用程序调用的插件。我使用 snoop 来找出元素本身的属性，但是堆栈还不允许我 post 图片。
FreeTextBox 可能位于加载到您的 window 的另一个用户控件或数据模板中，因此位于不同的 NameScope 中。 FindName 仅在当前名称范围内查找元素。
您需要使用 VisualTreeHelper API 递归遍历 window 的整个可视子树，并检查每个元素的名称 属性 以找到 FreeTextBox。只需使用 GetChildrenCount 和 GetChild 方法。
我需要一些有关 Powershell 和 WPF 的帮助。
我正在修改某人使用 WPF 和 powershell 制作的加载项。所以我不是 100% 确定 xaml 结构是如何布局的。我想做的是修改运行时生成的某个元素的Text 属性。我用的是Snoop2.8.0，找到了我要修改的元素，名字是属性"FreeTextBox"。我打算使用 FindName 方法获取元素，但是，FindName 方法 returns 什么都没有。
我在一些 post 中读到，有一个单独的东西叫做 contentPresenter，其中存储了这些运行时元素，我需要引用它才能进入我的文本框，但是，我没有知道怎么做。如果有人能指出正确的方向，我将不胜感激。

从第二段代码的最后一行可以看出，我正在尝试使用 findname 来获取从主应用程序创建的 FreeTextBox。不幸的是，我没有创建文本框的代码，因为这是一个从主应用程序调用的插件。我使用 snoop 来找出元素本身的属性，但是堆栈还不允许我 post 图片。
FreeTextBox 可能位于加载到您的 window 的另一个用户控件或数据模板中，因此位于不同的 NameScope 中。 FindName 仅在当前名称范围内查找元素。
您需要使用 VisualTreeHelper API 递归遍历 window 的整个可视子树，并检查每个元素的名称 属性 以找到 FreeTextBox。只需使用 GetChildrenCount 和 GetChild 方法。
