I have WPF ComboBox inside a data template (a lot of comboboxes in listbox) and I want to handle enter button. It would be easy if it was e.g. a button - I would use Command + Relative binding path etc. Unfortunately, I have no idea how handle key press with a Command or how to set event handler from template. Any suggestions?
You can use the EventSetter in the style you are setting the template with:
<Style TargetType="{x:Type ListBoxItem}">
<EventSetter Event="MouseWheel" Handler="GroupListBox_MouseWheel" />
<Setter Property="Template" ... />
</Style>
