System.Windows.Media.SolidColorBrush必须将IsFrozen设置为False才能编辑错误

我有一个WPF应用程序，我在其中修改了许多控件的模板。在许多不同的情况下，我得到了以下堆栈跟踪：System.Windows.Media.SolidColorBrush必须将IsFrozen设置为False才能编辑错误

Specified value of type 'System.Windows.Media.SolidColorBrush' must have IsFrozen set to false to modify.

我没有写任何试图改变任何画笔的瓦莱斯任何代码。我不知道哪个控件产生错误。我怀疑问题出在我修改的模板之一中，但我不知道哪一个。

我不知道如何跟踪和调试它。有人有想法吗？

讨厌！我不明确如何解决你的问题，但面对这种情况，我可能会改变Debug |例外|抛出CLR异常，然后在IDE中运行该应用程序，并在异常命中时查看汽车和本地人以尝试确定违规模板是什么。 –

我很幸运，在这一个。

我注意到错误发生在应用程序的两个不同的屏幕上。他们唯一的共同点就是Telerik的RadGridView控制。我已经对此控件进行了一些自定义修改，以支持将颜色托盘从“白天模式”更改为“夜间模式”。

我不知道我做了什么，但是我从app.xaml文件中删除了自定义模板，错误消失了。然后，我在Expression Blend中重新生成了模板，只替换了我所做颜色更改的Setters。而错误仍然消失！

我怀疑我可能在实施“夜间模式”的过程中升级了Telerik库，并且我有一个用于控件的过时模板。无论如何，这个错误已经消失了，至少现在是这样。
