我得到一個奇怪的間歇性錯誤,似乎與WPF工具包中的VisualStateManager有關。我正在開發一個使用Toolkit(2009年6月)的應用程序,但不是VisualStateManager。儘管如此,我收到以下錯誤:WPF工具包:VisualStateGroup錯誤?

'TextColor' name cannot be found in the name scope of 'System.Windows.Controls.Grid'. 

不用說,我不試圖更改網格控件上的TextColor屬性。

該異常不指向我的源代碼中的任何特定行。相反,它指向VisualStateManager中的一行 - 我已經複製下面的IL轉儲。我還發布了例外的全文。

有沒有人遇到過這個問題?謝謝你的幫助。

我簡直不敢相信。我在發佈這個問題後立即找到了我的答案。以下是發生的情況:我爲WPF工具包日曆控件創建了一個控件模板(我需要一個沒有導航按鈕的日曆)。所以,我修改了現有控件模板的副本,果然,控件模板確實嘗試在佈局Grid控件上設置(不存在的)TextProperty。它確實發生在原始控件模板使用的VisualStateGroup中。

所以,現在我所要做的就是弄清楚當我修改控件模板時是否引入了錯誤,或者在我開始擺弄控件模板之前是否存在錯誤。無論如何,神祕解決了!
