SelectTextOnFocus

The SelectTextOnFocus behavior makes it easy to select all text when a TextBox receives the focus.

  1. Add the following XML namespaces:
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
xmlns:catel="http://schemas.catelproject.com"
  1. Use the following definition:
<TextBox Text={Binding Amount}">
    <i:Interaction.Behaviors>
        <catel:SelectTextOnFocus />
    </i:Interaction.Behaviors>
</TextBox>
