WPF按钮单击事件

Question

我正在制作我的第一个WPF窗口.我在其上放置了一个网格,并将网格划分为行和列,如果调整窗口大小,则会自动调整大小.有两个按钮可以填充网格的两个单元格.按钮内容分别设置为"OK"和"EXIT".我有点难以理解的是,为什么这些按钮仅在我点击文本时才起作用,但如果我点击文本周围的区域并且仍在相应的按钮内,则不会做出反应.有没有办法让它可以点击按钮上的任何地方,它会按下(即使我点击文本很远的地方)？任何帮助将不胜感激,谢谢!

Answer 1

而不是将背景设置为{x:Null},将其设置为Transparent.

设置背景以{x:Null}使周围区域不可点击.空背景不响应鼠标事件.
