我有一个 WPF 应用程序，当主窗口最大化并且特定选项卡可见并且在我的选项卡控件顶部时，它经常挂起（变得完全无响应）。当窗户恢复下来时，它就像魅力一样。我能做些什么来解决这个问题？

有问题的选项卡有很多控件（文本框、图像、按钮、组合框、网格分割器、文本块、数据网格），我正在处理来自这些不同字段的事件，所以它是一个非常“忙碌”的网格。

这听起来类似于以下未解决的问题：WPF Datagrids freeze when windows Maximize ( http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/4641d825-cf80-4b76-a4f9-14183bb72bb2# 58dc7fdf-b43c-4782-833f-1d90401f1914 )

最后，让我说一下我没有按照我应该设计的那样设计应用程序，并且在主窗口中有超过 3000 行代码。我可能应该将这些繁忙的表单创建为用户控件。这会导致我的问题吗？

挂起可能来自绑定/事件处理程序中的无限循环/ ...也可能来自 wpf 无法解决您设置的所有约束（width/maxWidth/... with bindings...）以显示所有内容. 所以对于 xaml：布局、大小和视觉内容：让所有事情都变得非常简单，然后放回你的真实设计，直到它坏掉。对于代码：将其拆分为一些大块，并使用允许禁用/启用这些块的布尔值。然后将这些布尔值设置为 false/true，直到它运行正常。然后将非工作代码拆分成更小的部分并启用/禁用功能，直到它运行良好，以找到循环。（布尔值可能会阻止事件触发，在函数开始时返回默认值，......取决于你在做什么）

只是一个简单的问题，如果您对调试器进行（一些）暂停，它会在哪里停止？也可能让您了解核心循环问题。如果调试器从未在代码中停止，则很可能您遇到了 xaml 问题（布局）。

将代码分解一下可能是明智的，因为超过 3000 行不会有帮助。此外，如果您的主窗口上有很多控件，明智的做法是查看线程以及 WPF 执行 UI 线程的方式http://msdn.microsoft.com/en-us/library/ms741870.aspx 作为渲染WPF 中的控件，尤其是 DataGrid 中的控件很慢。当我上次使用 WPF 数据网格显示大量数据时，我实现了数据分页，然后加载第一页，同时仍检索数据以帮助加快速度。

希望这可以帮助

WPF 使用图形芯片的资源来呈现应用程序，尤其是在调整窗口大小时。您是否尝试过在不同的硬件上运行您的应用程序？你仍然得到相同的行为吗？

此外，它可能来自最大化事件处理程序中的一些自定义代码。

这简直太奇怪了。请确认症状。请定义“最大化”。只有当你点击最大化按钮时？如果在调整大小模式下，您可以拖动到全尺寸吗？

请发布 XAML 的窗口部分。

据我所知，没有特定的最大化事件 - 它只是一种调整大小。

根据this这个链接，可能有不同的处理最大化过大到最大值。“优先顺序也可以确定窗口最大化时的大小” 在此处输入链接描述 这是一个范围，但您可能在 Window XAML 中有一些设置会导致冲突。
