Answer 1

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..
