我有一个对话框，允许用户在自定义操作的帮助下选择网络共享。除非已设置此位置，否则我不希望用户能够继续安装。为了实现这个目标，我禁用了将用户带到下一个对话框的按钮控件。我的 CustomAction 设置了在该 PushButton 控件的 Condition 元素中检查的属性。
这一切都很好。困扰我的是我希望用户能够尽可能轻松地浏览对话框。这就是我制作 PushButton 控件的原因，它将用户带到浏览对话框 CustomAction，即对话框的默认控件。这也基于 CustomAction 设置的属性条件。设置属性后，将启用将用户带到下一个对话框的 PushButton 并将其设置为默认控件。正如您在屏幕截图中看到的那样，这确实有效。
有趣的是，Dialog 的 Default 控件确实发生了变化，但选项卡式控件仍然是打开浏览对话框 CustomAction 的 PushButton。这种情况导致当Return按下键时，浏览对话框再次打开，尽管属性已经设置，即文件夹路径已经选择。
有什么办法可以纠正这种行为吗？我希望根据属性的状态将焦点从一个控件移到另一个控件。我该怎么做？
另外： TabSkip 和 Default 属性如何结合在一起？
这是对话框的代码：
