列表視圖標籤導航列ListViewItems是網格列

Question

我有一個ListView水平呈現項目。每個項目是1列網格。外觀是列數爲動態的網格。所有這些工作，看起來像我想要的，除了標籤導航。我在ListView上設置了KeyboardNavigation.TabNavigation="Continue"，並在ItemContainerStyle上將KeyboardNavigation.IsTabStop設置爲false，這允許我通過一個項目中的每一行，然後繼續到下一個項目等。但是，我希望從第一個在第一個項目中行到第二個項目中的第一個行，等等，然後到下一個行。

Ex。

Item1Row1 - > Item2Row1 - > Item3Row1 - > ...

Item1Row2 - > Item2Row2 - > Item3Row2 - > ...

我已經建立了在控件的標籤索引每個單元格（我測試過的都是正確的），但我無法弄清楚我需要在ListView/ListViewItems中啓用TabIndexes的設置。任何幫助將不勝感激。這裏的xaml ...

我決定在後面的代碼中處理這個問題。我刪除了xaml中文本框的選項卡索引。解決方案並不美觀，但在我看來，比刪除列表框並對所有通道進行編碼以便我可以使用Tab索引更好。

預覽鍵按下處理程序上的ListView：

private void LanesListView_PreviewKeyDown(object sender, KeyEventArgs e) 
{ 
    UIElement uie = e.OriginalSource as UIElement; 

    // 'Ctrl + Tab' or 'Shift + Enter' (Reverse Tab) 
    if ((e.Key == Key.Tab || e.Key == Key.Return) && 
     (Keyboard.Modifiers & ModifierKeys.Shift) == ModifierKeys.Shift && 
     uie != null) 
    { 
     MoveFocusPrevious(uie, (UIElement)sender); 

     e.Handled = true; 
    } 
    else if ((e.Key == Key.Tab || e.Key == Key.Return) && uie != null) 
    { 
     // Normal 'Enter' or 'Tab' key click 
     MoveFocusNext(uie, (UIElement)sender); 

     e.Handled = true; 
    } 
} 

移動焦點方法：

private void MoveFocusNext(UIElement uie, UIElement sender) 
{ 
    if(!uie.MoveFocus(new TraversalRequest(FocusNavigationDirection.Right))) 
    { 
     uie.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next)); // Move Down 
     uie = (UIElement)Keyboard.FocusedElement; 
     MoveFocusToFirst(uie, sender); // Move to to first 
    } 
} 

private void MoveFocusPrevious(UIElement uie, UIElement sender) 
{ 
    if (!uie.MoveFocus(new TraversalRequest(FocusNavigationDirection.Left))) 
    { 
     uie.MoveFocus(new TraversalRequest(FocusNavigationDirection.Previous)); // Move Up 
     uie = (UIElement)Keyboard.FocusedElement; 
     MoveFocusToLast(uie, sender); // Move focus to last 
    } 
} 

private void MoveFocusToLast(UIElement uie, UIElement sender) 
{ 
    bool isLast = false; 

    // Move right until hitting last item 
    while(!isLast) 
    { 
     // If Focus cannot be moved, it is last item. 
     isLast = !uie.MoveFocus(new TraversalRequest(FocusNavigationDirection.Right)); 
     uie = (UIElement)Keyboard.FocusedElement; 
    } 
} 

private void MoveFocusToFirst(UIElement uie, UIElement sender) 
{ 
    bool isFirst = false; 

    // Move left until hitting last item 
    while (!isFirst) 
    { 
     // If Focus cannot be moved, it is last item. 
     isFirst = !uie.MoveFocus(new TraversalRequest(FocusNavigationDirection.Left)); 
     uie = (UIElement)Keyboard.FocusedElement; 
    } 
}
