WPF MVVM Framework - DXBinding, DXCommand, and DXEvent Extensions

This example demonstrates use cases of the DXBinding, DXCommand, and DXEvent markup extensions.

• The DXBinding allows you to use expressions inside binding paths.

  Text="{DXBinding 'StringValue+DoubleValue.ToString()', Mode=OneWay}"
  

• With the DXCommand, you can bind a command property and define methods to call right in xaml.

  Command="{DXCommand Execute='$MessageBox.Show(@e(message).Text, @e(title).Text)',
                      CanExecute='@e(isEnabled).IsChecked'}"

• The DXEvent allows you to bind an event to methods.

  Click="{DXEvent '$MessageBox.Show($string.Format(@r(clickBindingStringFormat), @r(clickBinding)), Title)'}"
