Using EventSetters in Custom-Control to add MouseDoubleClick to a ListViewItem

I am creating a custom control that is supposed to auto-complete stuff. For this, a Popup is getting created where the user can pick the wanted item.
This all works perfectly fine already, with a tiny problem: I want those items (presented inside of a ListView) to also auto-complete using a double click.
This however, presents a problem to me as i cannot add an EventSetter onto the style for the corresponding ListViewItem.
I want to avoid having to add a dependency property with some ICommand to relay the whole thing via attached properties.
XAML code (broken down):
<Style x:Key="{x:Type local:AutoCompleteTextBox}" TargetType="{x:Type local:AutoCompleteTextBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:AutoCompleteTextBox}">
<!-- ... -->
<Popup x:Name="PART_Popup" PlacementTarget="{Binding ...}" IsOpen="{Binding ...}">
<ListView ItemTemplate="{Binding ...}" ItemsSource="{Binding ...}">
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
<!-- 'ResourceDictionary' root element requires a x:Class attribute to support event handlers in the XAML file. Either remove the event handler for the MouseDoubleClick event, or add a x:Class attribute to the root element. -->
<EventSetter Event="MouseDoubleClick" Handler="ListViewItem_MouseDoubleClick"/>
</Style>
</ListView.ItemContainerStyle>
</ListView>
</Popup>
<!-- ... -->
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

So where are you defining the event handler? And what are you doing in it?

nowhere currently @mm8 as it is not possible like it is done above. I want to have it inside of myAutoCompleteTextBoxControl. The Style is inside theThemes.xaml. In the end, the double click is supposed to auto-complete (aka replace) theTextfield of the control.

In the answer to this question is the following suggestion: To attach an event handler override the OnApplyTemplate of the custom control and add the event handler in code. Does that help?

@PhilJollans theoretically you are right but practically it is not possible due the targeted items being potentially not existing atOnApplyTemplatecalltime. It is aboutListViewItemafterall :/
