Attempting to get property of control when using applying EventTriggerBehavior via styles

[Jeremyltw]

Hi,

So, I am implementing this within the styles of the UserControl

<UserControl.Styles>
	<Style Selector="TextBox">
			<Setter Property="(i:Interaction.Behaviors)">
				<i:BehaviorCollectionTemplate>
					<i:BehaviorCollection>
						<ia:EventTriggerBehavior EventName="LostFocus">
							<ia:InvokeCommandAction
								Command="{Binding TestCommand}"
								CommandParameter="{Binding RelativeSource={RelativeSource Self}, Path=Name}"/>
						</ia:EventTriggerBehavior>
					</i:BehaviorCollection>
				</i:BehaviorCollectionTemplate>
			</Setter>		
		</Style>
</UserControl.Styles>

However, the command parameter doesn't seem to get the textbox's name. If I were to put this directly into a textbox,eg.

<TextBox
	x:Name="tbName">

		<i:Interaction.Behaviors>
			<<ia:EventTriggerBehavior EventName="LostFocus">
				<ia:InvokeCommandAction
					Command="{Binding TestCommand}"
					CommandParameter="{Binding RelativeSource={RelativeSource Self}, Path=Name}"
						/>

			</ia:EventTriggerBehavior>

		</i:Interaction.Behaviors>
	</TextBox>

the textbox name appears in the command parameters within the viewmodel.

Is there a way to get the property of the control within the commandparameter when the behavior is set at the styles instead of directly within the control?
