我知道以前有人问过这类问题,但我尝试了这些建议无济于事,所以希望一些新鲜的眼睛可以帮助我解决这个问题。
我有一个自定义控件,它基本上是一个带有网格的边框,其中包含 2 个文本框和一个按钮。
该控件还有一个在代码隐藏中添加的八边形。
按钮的单击事件不会触发。我收集它可能与它上面的控件获取点击事件而不是按钮有关,但我不知道如何解决它。或者可能是因为八边形是后来在后面的代码中绘制的。
我尝试了很多不同的东西,移动按钮,添加另一个网格,将背景设置为透明。这让我发疯了。
下面是代码。

有任何想法吗?

更新:
我已经测试过将 MouseLeftButtonUp 事件快速放在网格和边框上。
当我单击边框时,首先触发网格事件,然后触发边框事件,但是如果我单击按钮,则不会触发。这是否意味着 Button 位于网格和边框上方,因此应该触发事件?
在此期间,我也会尝试其他一些建议。

更新 2:
它变得陌生。我将按钮移到顶部,然后单击事件触发。我看到的是,从某个 Y 点及以下,绝对没有 mouseleftbuttonup 或 click 事件触发,nada。这是没有意义的。如果我从底部开始并单击缓慢向上移动,那么在某个点,所有事件都开始触发。

大家好,
在逐一删除控件以查看导致问题的原因后,我现在知道它是边界控件。如果我删除它,一切正常,当它回来时,和以前一样的问题。有任何想法吗?
谢谢

大家好,
好的,所以我终于解决了问题,以防万一有人发现自己处于类似情况。它与那个页面完全没有关系。我正在从不同页面的框架中加载页面,看起来我必须在主页的网格中设置许多行定义。在我更正之后,一切正常。
谢谢
