  1. POWPF ListBox: how to update data with binding
    text
    copied!<p>I have listbox that displays information about list of objects:</p> <pre><code> &lt;ListBox Grid.Column="0" Height="152" Name="CustomersList" HorizontalAlignment="Stretch"&gt; &lt;ListBox.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;TextBlock Text="{Binding Path=Name, Mode=OneWay}"/&gt; &lt;/DataTemplate&gt; &lt;/ListBox.ItemTemplate&gt; &lt;/ListBox&gt; </code></pre> <p>I would show more detailed information about selected item in another block, but I don't know (and can't find) how to bind selected item to those block data context. I guess it should be something like this:</p> <pre><code> &lt;Grid Grid.Column="1" DataContext="{Binding Path=ItemSelected, UpdateSourceTrigger=PropertyChanged}" VerticalAlignment="Top"&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition Width="150"/&gt; &lt;ColumnDefinition Width="250"/&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition /&gt; &lt;RowDefinition/&gt; &lt;RowDefinition/&gt; &lt;/Grid.RowDefinitions&gt; &lt;TextBlock Grid.Row="0" Grid.Column="0" Text="Id" VerticalAlignment="Center" /&gt; &lt;TextBox Grid.Row="0" Grid.Column="1" Text="{Binding Path=Id}" VerticalAlignment="Center"/&gt; &lt;TextBlock Grid.Row="1" Grid.Column="0" Text="Name" VerticalAlignment="Center"/&gt; &lt;TextBox Grid.Row="1" Grid.Column="1" Text="{Binding Path=Name}" VerticalAlignment="Center"/&gt; &lt;StackPanel Grid.Row="2" Grid.ColumnSpan="2" Orientation="Horizontal" HorizontalAlignment="Center"&gt; &lt;Button Content="Add new" /&gt; &lt;Button Content="Store changes" /&gt; &lt;/StackPanel&gt; &lt;/Grid&gt; </code></pre> <p>But the problem is that data item to be binded to the grid is not specified anywhere and I don't know how to do that.</p> <p>Any suggestion would be wellcome.</p> <p>Thanks!</p> <p>P.S. I've tried to specify CustomersList.ItemsSource as DataContext for the Grid - this didn't give any result.</p>
