Hi Guys,
I've spent far too much time with this and can't find the mistake. Maybe I'm missing something very obvious or I may have just found a bug in the WPF Element Host for
Winforms.
I am binding a ListView to a ObeservableList that lives on my ProductListViewModel.
I'm trying to implement searching for the ListView with the general Idea to just change the ObservableList with a new list that is filtered.
Anyway, the ListView Binding code looks like this:
<ListView ItemsSource="{Binding Path=Products}" SelectedItem="{Binding Path=SelectedItem}" SelectionMode="Single">
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
<Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}"></Setter>
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}"></TextBlock>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
And the ViewModel code is as vanilla as it can get:
private ObservableCollection<ProductViewModel> products;
public ObservableCollection<ProductViewModel> Products
{
get { return products; }
private set
{
if (products != value)
{
products = value;
OnPropertyChanged("Products");
}
}
}
Now the problem here: Once I debug into my OnPropertyChanged method, I can see that there are no subscribers to the PropertyChanged event (it's null), so nothing happens on the UI..
I already tried Mode=TwoWay and other Binding modes, it seems I can't get the ListView to subscribe to the ItemsSource...
Can anyone help me with this? I'm just about to forget about the ElemenHost and just do it in
Winforms
greetings Daniel
