我正在使用以下层次结构
WPF form
- Grid
- GroupBox
- Grid
- multiline textbox
你能告诉我如何在WPF中垂直拉伸表单时自动增加多行文本框的高度。表格可由用户调整大小。

将TextBox的水平和垂直对齐设置为Stretch。此外，您还必须设计Grid - GroupBox - Grid，其中包含TextBox，这样当窗口大小增加时它们也会增加高度。您可以通过将这些控件的高度设置为*或其对齐等于Stretch（取决于控件）来执行此操作。否则TextBox不会增加它的高度。

XAML没有按照预期的方式工作，因为在最外层的网格中，最后四行声明是没有用的，删除那些并使第三行高度= *得到所需的结果
