帮助！

在我正在开发的wpf应用程序中使用Touch事件时遇到问题摔跤。

让我设置场景......

我有一个主窗口（fmMainWindow），上面有一个文本框。打开时，窗口被编码为以屏幕为中心。在Textbox的TouchUp事件中，我有使用语法ShowDialog打开另一个窗口（fmKeypad_Numeric）的代码。该窗口也居中。它是一个数字小键盘，上面有编号按钮。

我的问题是主窗口上使用的触摸事件对它打开的窗口上的按钮的Click事件有影响。

看起来触摸事件发生在屏幕上的任何地方，下一个窗口上的按钮在同一位置打开似乎最初有某种焦点＆＃39; （好像鼠标悬停在它上面）。

如果您点击最初具有焦点＆＃39;的按钮，则点击事件会按预期触发。

但是，如果您首先点击其他一个没有关注焦点的按钮。它的点击事件不会触发。需要再次点击才能触发？

我已经使用Snoop来查看事件是如何触发的，以及当您点击其他按钮之一时，这些按钮最初没有＆＃39;焦点＆＃39;，与具有＆＃的按钮相关的事件39;聚焦＆＃39;火??

有人有任何想法吗？我在这个上花了好几天。

两个窗口的代码在

之下

非常感谢，
