我是新的XAML和混合，但这里是我试图做的。我正在开发一个应用程序，其中我需要放置一个

文本框

（或任何输入控件），但它不应该具有

文本框

的属性。请参考下图

我想要帮助实现下面提到的功能

点击-它应该允许我编辑值，而不突出显示背景区域-这通常是

文本框

所做的事情

我不需要任何边界

一旦我停止编辑并在控件外点击，它应该看起来像一个

TextBlock

，再次点击它可以让您正常编辑

您有两个（简单）选项：

您可以创建一个

Grid

元素，并将

TextBlock

和

TextBox

放在里面，这样它们就重叠了。然后将

文本框的不透明度
设置为0.01（不要完全隐藏，因为这样不起作用）


您可以修改VisualStudio中文本框
元素的属性，只需将焦点内和焦点外的背景
设置为透明
。您还可以在属性中将边框
设置为透明
