找不到綁定的源代碼'RelativeSource FindAncestor，AncestorType ='MahApps.Metro.Controls.Glow'，AncestorLevel ='''

Question

我創建了一個wpf應用程序，其中我使用了MahApps Metro工具查看窗口。我的應用程序運行正常，但輸出窗口中顯示綁定錯誤。我沒有使用任何在該錯誤中提到的代碼。

錯誤是：

不能用於與參考1 ' '結合 '的RelativeSource FindAncestor，AncestorType =' MahApps.Metro.Controls.Glow' AncestorLevel =' 找到源。 BindingExpression：路徑= GlowColor;的DataItem = NULL; 目標元素是'SolidColorBrush'（HashCode = 9047482）;目標 屬性是「顏色」（Type「色彩」）

XAML代碼：

Answer 1

聽起來好像與你的全局樣式，模板或用戶控件綁定錯誤。

我寫了一些關於調試綁定錯誤here。

總之，如果你在分號和逗號添加換行符，並讀取錯誤向後

做到這一點與你的錯誤，你會得到這個最簡單的方法：

 
target property is 'Color' (type 'Color') 
target element is 'SolidColorBrush' (HashCode=9047482); 
DataItem=null; 
Cannot find source for binding with reference 'RelativeSource FindAncestor, 
    AncestorType='MahApps.Metro.Controls.Glow', 
    AncestorLevel='1''. 
    BindingExpression:Path=GlowColor; 

它告訴你：

• 某處你有一個Color屬性導致綁定錯誤。

• 該屬性是SolidColorBrush對象

• 該項目的DataContext是null。

• 而且結合它有問題的評估是一個RelativeSource綁定，進一步尋找MahApps.Metro.Controls.Glow對象了視覺樹，以便它可以找到該對象的GlowColor屬性，並使用它。

嘗試在您的應用程序上搜索GlowColor並查看是否可以找到它。這很可能在您的Colours.xaml文件中，因爲它可能包含您的SolidColorBrush對象。
