按鈕列表中的單個選項按鈕

Question

目標：
需要在列表視圖中選擇包含單個行的按鈕。

問題：
當您點擊位於listview內部的按鈕時，不知道如何在列表視圖中進行單個選擇。在一個簡單的解釋中，當點擊按鈕時，沒有選擇將被應用在列表視圖的行中

如果在輸入按鈕的方法之前應用選擇會很好因爲我需要從listview的單選中獲取信息應該發送給業務邏輯。

Answer 1

你不應該需要選擇ListViewItem的，你可以從Button的DataContext讓您的數據對象，你不需要從數據其他行無論如何你都想要一個選擇。

在事件處理程序：

var data = (sender as FrameworkElement).DataContext as MyData; 

（在一個側面說明，他這樣說，你需要在所有的選擇。如果不使用ItemsControl？）

爲了使ListViewItem選擇自己，如果按鈕被點擊，你可以使用這樣一個ItemContainerStyle：

<ListView.ItemContainerStyle> 
    <Style TargetType="{x:Type ListViewItem}"> 
     <Setter Property="IsSelected" 
       Value="{Binding RelativeSource={RelativeSource Self}, Path=IsKeyboardFocusWithin, Mode=OneWay}" /> 
    </Style> 
</ListView.ItemContainerStyle> 

這裏是使用後的ListView失去聚焦其保留所選擇的項目的動畫的替代方案（僅與ListView.SelectionMode是Single工作，它似乎並不可能以清除利用動畫先前的選擇）：

<Style TargetType="{x:Type ListViewItem}"> 
    <Style.Triggers> 
     <DataTrigger 
       Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsKeyboardFocusWithin, Mode=OneWay}" 
       Value="True"> 
      <DataTrigger.EnterActions> 
       <BeginStoryboard> 
        <Storyboard> 
         <BooleanAnimationUsingKeyFrames Storyboard.TargetProperty="IsSelected"> 
          <DiscreteBooleanKeyFrame KeyTime="0" Value="True" /> 
         </BooleanAnimationUsingKeyFrames> 
        </Storyboard> 
       </BeginStoryboard> 
      </DataTrigger.EnterActions> 
     </DataTrigger> 
    </Style.Triggers> 
</Style>
