Vista - databinding trigger

I try to create a ListBoxStyle associated with several templates. I would
like to bind dynamically each items to its corresponding template, according
to the value of a field on items.

Have you already use a Trigger with a Binding condition (source code below),
or is there an other way to do a such construction.

<Style x:Key="SmallRosterListItem" TargetType="{x:Type ListBoxItem}">
<Setter Property="Cursor" Value="Hand" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="Template" Value="{StaticResource
item_SmallRosterDetails}" />

<Setter Property="Padding" Value="0,0,0,0" />
<Style.Triggers>
<Trigger Property="Binding XPath=gender" Value="Male">
<Setter Property="Template" Value="{StaticResource
item_BigRosterMale}" />
</Trigger>
</Style>
