TextBox中的奇怪交叉
TextBox出现问题。如果我将属性TextWrap设置为NoWrap，我会在TextBox内看到一个十字架。我可以删除或隐藏这个十字架吗？
UPD：解决我的问题：
- 将
TextWrap设为Wrap - 我使用
FontSize72px，并为Height72px设置TextBox。
它看起来像你的TextBox没有多线并且在里面交叉。

十字架是内置于default template的DeleteButton，如果您在该链接中查看它并转到默认模板的底部，您会看到DeleteButton模板底部的Button。你可以在那里删除它或我在上一篇文章中显示的方式。 ：）
要访问模板（最快捷方式），请右键单击TextBox并选择“编辑模板”，然后编辑副本（将模板放入window.resources）并明确定义或编辑原始模板。
PS-您可以在家中为观众添加您上一篇文章中的图像。

这里老兄，这里是删除按钮的默认模板的副本。只需将它放在您的UserControl.Resources，或Window.Resources，或Application.Resources中，或者只是它可以作为StaticResource找到它。
