Properties.Settings with ItemsControl can't show Value

Question

I want to iterate trough my Settings (two settings Files, Settings and Monitor) and Show them in an ItemsControl. The Problem is: I can only bind the DefaultValue (referenced to the Value Bound to the ItemsControl) and not the actual Value.

<UserControl x:Class="ProjectPerformance.Views.Settings"

            <Button x:Name="btnRestart" Width="150" Margin="5" HorizontalAlignment="Right" Content="Restart App" FontSize="15" PreviewMouseLeftButtonDown="btnRestart_PreviewMouseLeftButtonDown"/>
        </StackPanel>
    </ScrollViewer>
</Grid>

I think it could Work like this:

<TextBox Text="{Binding Source={x:Static properties:Monitor.Default}, Path={Binding Name}}"/>

But I don't know how to bind a value inside a Binding.

You can bind to to the PropertyValues property to get the current SettingsPropertyValue values, e.g.:

<ItemsControl ItemsSource="{Binding Source={x:Static properties:Monitor.Default}, Path=PropertyValues}">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition />
                    <ColumnDefinition />
                    <ColumnDefinition />
                </Grid.ColumnDefinitions>
                <TextBlock Text="{Binding Name}" />
                <TextBlock Grid.Column="1" Text="{Binding Property.DefaultValue}" />
                <TextBlock Grid.Column="2" Text="{Binding PropertyValue}" />
            </Grid>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

Note that for the PropertyValues property to actually return any values, you apparently need to either set a property or retrieve each property first. You could do this dynamically using some reflection:

foreach (System.Configuration.SettingsProperty property in Monitor.Default.Properties)
    typeof(Monitor).GetProperty(property.Name).GetValue(Monitor.Default);
