Is there any way to update listbox items text after updating it in textboxes? I wanna do it only with bindings if it is possible. Listbox is reading from list, but list isn't updating so it's never gonna change, unless I add new item to list. Here is code
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication1"
Title="MainWindow" Height="350" Width="525">
<Grid>
<DockPanel VerticalAlignment="Top" HorizontalAlignment="Left">
<Button Name="dodaj" Width="40" Margin="5" Click="dodaj_Click">Dodaj</Button>
<Button Name="usun" Width="40" Margin=" 5" Click="usun_Click">Usuń</Button>
</DockPanel>
<DockPanel HorizontalAlignment="Left" VerticalAlignment="Center" DataContext="{Binding ElementName=lista, Path=osoba, Mode=TwoWay}">
<ListBox Name="lb" ItemsSource="{Binding}" Width="200" Height="230">
</ListBox>
</DockPanel>
<DockPanel HorizontalAlignment="Right" VerticalAlignment="top">
<WrapPanel>
<StackPanel>
<Label>Imię</Label>
<Label>Nazwisko</Label>
<Label>Email</Label>
<Label>Telefon</Label>
</StackPanel>
<StackPanel DataContext="{Binding ElementName=lb, Path=SelectedItem, UpdateSourceTrigger=LostFocus}" TextBoxBase.TextChanged="zmiana">
<TextBox Width="200" Margin="3" Name="imie" Text="{Binding Path=imie}"></TextBox>
<TextBox Width="200" Name="nazwisko" Text="{Binding Path=nazwisko}"></TextBox>
<TextBox Width="200" Margin="3" Name="email" Text="{Binding Path=email}"></TextBox>
<TextBox Width="200" Name="telefon" Text="{Binding Path=telefon}"></TextBox>
</StackPanel>
</WrapPanel>
</DockPanel>
</Grid>
