[英]WPF Listbox binding: SelectedItem not setting
I have a ListBox simplified to the following XAML 我将ListBox简化为以下XAML
<ListBox ItemsSource="{Binding Properties}"
DisplayMemberPath="Name"
SelectedItem="SelectedProperty" />
and in my ViewModel: 在我的ViewModel中:
private List<Property> propertyList;
private Property selectedProperty;
public List<Property> Properties
{
get
{
return propertyList;
}
set
{
propertyList = value;
NotifyPropertyChanged("Properties");
}
}
public Property SelectedProperty
{
get
{
return selectedProperty;
}
set
{
NotifyPropertyChanged("SelectedProperty");
selectedProperty= value;
}
}
My List box populates fine, but no matter what I try I cannot seem to get the SelectedProperty to update when I select an item in my list box. 我的列表框填充正常,但无论我尝试什么,当我在列表框中选择一个项目时,我似乎无法更新SelectedProperty。 I have tried switching it all around to use
ObservableCollection
rather than List
and adding an Event handler for CollectionChanged, but this has not worked. 我已经尝试将其全部切换为使用
ObservableCollection
而不是List
并为CollectionChanged添加事件处理程序,但这没有用。
I am sure I am missing something stupid, and cannot see the wood for the trees. 我确信我错过了一些愚蠢的东西,并且看不到树木的木头。 I am reaching the end of my tether and need someone to step in and help.
我到达了我的系绳的末端,需要有人介入并提供帮助。
You need to bind to the SelectedProperty
: 您需要绑定到
SelectedProperty
:
<ListBox ItemsSource="{Binding Properties}"
DisplayMemberPath="Name"
SelectedItem="{Binding SelectedProperty}" />
