ListView: Set the right column to auto width

Hello,

The following XAML code is a ListView with 3 columns.

How can I make the right column width to be "Auto" ?

<ListView Grid.Row="3" x:Name="Log"><ListView.View><GridView><GridViewColumn Header="Severity" DisplayMemberBinding="{Binding Icon}"/><GridViewColumn Header="Time" DisplayMemberBinding="{Binding Time}"/><GridViewColumn Header="Message" Width="100" DisplayMemberBinding="{Binding Msg}"/></GridView></ListView.View></ListView>

Regards,

Z.V
