將ListBoxItem的IsSelected屬性綁定到其源對象上的屬性

Question

我有一個WPF ListBox控件，我將其ItemsSource設置爲一組項目對象。如何將ListBoxItem的IsSelected屬性綁定到相應項目對象的Selected屬性，而無需將該對象的實例設置爲Binding.Source？

Answer 1

只是覆蓋ItemContainerStyle：

<ListBox ItemsSource="..."> 
    <ListBox.ItemContainerStyle> 
     <Style TargetType="{x:Type ListBoxItem}"> 
     <Setter Property="IsSelected" Value="{Binding Selected}"/> 
     </Style> 
    </ListBox.ItemContainerStyle> 
    </ListBox> 

哦，順便說一句，我想你想從dr.WPF這美妙的文章：ItemsControl: A to Z。

希望這會有所幫助。

我正在尋找代碼解決方案，所以這裏是翻譯。

System.Windows.Controls.ListBox innerListBox = new System.Windows.Controls.ListBox(); 

//The source is a collection of my item objects. 
innerListBox.ItemsSource = this.Manager.ItemManagers; 

//Create a binding that we will add to a setter 
System.Windows.Data.Binding binding = new System.Windows.Data.Binding(); 
//The path to the property on your object 
binding.Path = new System.Windows.PropertyPath("Selected"); 
//I was in need of two way binding 
binding.Mode = System.Windows.Data.BindingMode.TwoWay; 

//Create a setter that we will add to a style 
System.Windows.Setter setter = new System.Windows.Setter(); 
//The IsSelected DP is the property of interest on the ListBoxItem 
setter.Property = System.Windows.Controls.ListBoxItem.IsSelectedProperty; 
setter.Value = binding; 

//Create a style 
System.Windows.Style style = new System.Windows.Style(); 
style.TargetType = typeof(System.Windows.Controls.ListBoxItem); 
style.Setters.Add(setter); 

//Overwrite the current ItemContainerStyle of the ListBox with the new style 
innerListBox.ItemContainerStyle = style;
