You should modify the ListView.itemTemplate property and add a data template.

Using an item template with data template you can add checkboxes, comboboxes, textboxes, buttons, etc. for every line item in your list view. Here is an example from an answer here in SO.

<ListView ItemsSource="{Binding Links}" x:Name="ListView1">
        <ListView.ItemTemplate>
            <DataTemplate>
                <Border>
                    <Button Command="{Binding ElementName=ListView1, Path=DataContext.GetOddsCommand}" CommandParameter="{Binding}">
                         <TextBlock Text="{Binding}" />
                    </Button>
                </Border>
            </DataTemplate>
        </ListView.ItemTemplate> 
</ListView>

Except you only have to use a combobox instead of a button and use proper bindings..

The CommandParameter is responsible for passing values to the Command. You can pass the specific field (column) from your item to the event. As I've said you have to use proper bindings as I only extracted the sample from some answer here in SO.
