如何从WPF列表框中选中的单选按钮中选中的列表项

Question

列表框的图片如下：

Listbox with Dynamic column with check boxes and static radio buttons

我要寻找从列表框中选择的项目和选定的单选按钮每个选择的项目

<ListBox Height="226" HorizontalAlignment="Left" Margin="404,339,0,0" Name="listBoxItems" VerticalAlignment="Top" Width="282" SelectionChanged="listBoxItems_SelectionChanged" SelectionMode="Multiple"> 
      <ListBox.ItemTemplate> 
       <DataTemplate> 
        <StackPanel Orientation="Horizontal" Margin="10,5,0,0"> 
         <CheckBox Width="130" x:Name="chbPrescr" Content="{Binding}" IsChecked="{Binding RelativeSource={RelativeSource AncestorType={x:Type ListBoxItem}}, Path=IsSelected}"> 
          <!--<TextBlock Text="{Binding}" Width="115"></TextBlock>--> 

         </CheckBox> 
         <RadioButton x:Name="rdOD" Width="40" Content ="OD" Checked="rdOD_Checked" /> 
         <RadioButton x:Name="rdBD" Width="40" Content ="BD" Checked="rdBD_Checked"/> 
         <RadioButton x:Name="rdTDS" Width="40" Content ="TDS" Checked="rdTDS_Checked"/> 
        </StackPanel> 
       </DataTemplate> 
      </ListBox.ItemTemplate> 
     </ListBox> 

，并在回发事件我得到选中的列表项，但不是选定的单选按钮为选中的列表项

foreach (var items in listBoxItems.SelectedItems) 
{ 
    string a = items.ToString(); 
    ItemCollection itemCollection = listBoxItems.Items; 
    object currentItem = itemCollection.CurrentItem; 
} 

我需要知道如何获得每种选定药物的类别。由于

您可以在RadioButtons的IsChecked属性绑定到数据类的源属性：

WPF + MVVM + RadioButton : Handle binding with single property

这是最好的解决办法。

最快的国家之一可能是发现在可视化树中选择RadioButton：

private void listBoxItems_SelectionChanged(object sender, SelectionChangedEventArgs e) 
{ 
    foreach (var items in listBoxItems.SelectedItems) 
    { 
     ListBoxItem lbi = listBoxItems.ItemContainerGenerator.ContainerFromItem(items) as ListBoxItem; 
     if (lbi != null) 
     { 
      RadioButton rb = FindVisualChildren<RadioButton>(lbi).FirstOrDefault(x => x.IsChecked == true); 
      if (rb != null) 
      { 
       MessageBox.Show("selected: " + rb.Content.ToString()); 
      } 
     } 
    } 
} 

private static IEnumerable<T> FindVisualChildren<T>(DependencyObject depObj) where T : DependencyObject 
{ 
    if (depObj != null) 
    { 
     int NbChild = VisualTreeHelper.GetChildrenCount(depObj); 

     for (int i = 0; i < NbChild; i++) 
     { 
      DependencyObject child = VisualTreeHelper.GetChild(depObj, i); 

      if (child != null && child is T) 
      { 
       yield return (T)child; 
      } 

      foreach (T childNiv2 in FindVisualChildren<T>(child)) 
      { 
       yield return childNiv2; 
      } 
     } 
    } 
}
