我遇到了綁定變量顏色的問題，這是我在類中定義的，以便它可以爲我填充區域。Windows phone將xaml綁定到類

我希望綁定的SolidColorBrush的顏色，使其充滿我的領域。

如果您的UserControl_Portugal控件將它的DataContext設置爲「Country」的一個實例，它應該可以工作。（例如：DataContext = new Country（）;） –

@ jonasN89你有沒有找到其他解決方案？ – loop

我認爲你應該重新安排你的代碼，並開始使用MVVM。您可以很容易地通過MVVM使用它。

轉到Nuget並搜索MVVM或Galsoft。

在模型中，你可以定義你想要的。然後你可以創建你的國家作爲一個視圖。然後綁定很容易在ViewModel中完成。

這將需要一些時間來進入它。但是當你做到一切都很簡單！

我也發現了這是前進的方向，所以我開始一個新的，看看它是否會奏效。 – JonasN89

將其綁定到您的網格這樣的..

<Grid HorizontalAlignment="Left" Height="100" VerticalAlignment="Top" Width="88" Background="{Binding color}"/>

，並在你的類..它實現InotifyPropetyChanged好做...你可以做這樣的..

在你的班級做這個..

class Country:INotifyPropertyChanged 
{ 


public Country() 
    { 
     this.InitializeComponent(); 
this.DataContext = this; 
} 

private SolidColorBrush _color; 

    public SolidColorBrush color 
    { 
     get 
     { 
      return _color; 
     } 
     set 
     { 
      _color = value; 
      FirePropertyChanged("color"); 
     } 

    } 

public event PropertyChangedEventHandler PropertyChanged; 
    protected void FirePropertyChanged(string propertyName) 
    { 
     if (this.PropertyChanged != null) 
     { 
      this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); 
     } 
    } 

}

謝謝，但似乎有InitializeComponent和DataContext的問題。這是因爲我錯過了一些代碼或？ – JonasN89

看@ JonasN89你可以使用綁定只有當變量被定義爲像屬性..你的顏色沒有任何獲得（這將在xaml中綁定時使用顏色時調用），所以你沒有得到你的顏色..我的方式以爲你是純粹的基本..所以剛剛閱讀數據綁定的基礎知識，那麼你會發現我告訴你.. – loop

只是檢查任何基本的xaml數據綁定的例子..在谷歌.. – loop
