是否有人將MahApps.Metro樣式應用於NavigationWindow?我已經爲一個Window實現了它,但是需要將它應用於帶有Pages的NavigationWindow。我嘗試過擴展NavigationWindow並像MetroWindow那樣添加修改,但沒有運氣。窗口有一個標準的標題欄和邊框,內容完全是黑色的。將MahApps.Metro樣式應用於NavigationWindow

要,我使用的是MetroWindow作爲我的主要瀏覽窗口,並MetroWindow它處理導航內的Frame做到這一點。

導航窗口

<Controls:MetroWindow x:Class="TestWpfApplicationMahApps.Metro.NavWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
         xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro" Title="NavWindow" Height="300" Width="300"> 
    <Window.Resources> 
     <ResourceDictionary> 
      <ResourceDictionary.MergedDictionaries> 
       <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colours.xaml" /> 
       <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" /> 
       <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" /> 
       <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" /> 
       <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" /> 
      </ResourceDictionary.MergedDictionaries> 
     </ResourceDictionary> 
    </Window.Resources> 
    <Frame Source="Page1.xaml" NavigationUIVisibility="Hidden"></Frame> 
</Controls:MetroWindow> 

這讓我不會改變任何導航邏輯的,它可以從NavigationService就像它使用NavigationWindow時被調用。

1的.cs

/// <summary> 
/// Interaction logic for Page1.xaml 
/// </summary> 
public partial class Page1 : Page 
{ 
    public Page1() 
    { 
     InitializeComponent(); 
    } 

    private void button1_Click(object sender, RoutedEventArgs e) 
    { 
     NavigationService.Navigate(new Page2()); 
    } 
} 
+0

我不得不放棄幀的名稱,即:<幀x:名稱= 「_ mainFrame中」 ......和導航代碼更改爲:_mainFrame.Navigate(新MyOtherPage());仍然很好的解決方案,特別是你想刪除導航histroy控制用戶界面.. – BENN1TH
