I am trying to work to the MVVM principles within a small WPF project using c#. I have a List box that is populated with Checkboxes created through binding back to the ViewModel. I also have a command bound to the checkboxes and wish to pass the checkbox Content as a commandParameter. I was looking at something like the below

Unfortuetly because the Checkboxes are created through a binding I don’t have the element name.

The code for ListBox / ListBoxItem Style is below

<Style x:Key="CheckBoxListStyle" TargetType="{x:Type ListBox}">   <Setter Property="SelectionMode" Value="Multiple"></Setter>   <Setter Property="ItemContainerStyle">   <Setter.Value>   <Style TargetType="{x:Type ListBoxItem}" >   <Setter Property="Margin" Value="2" />   <Setter Property="Template">   <Setter.Value>   <ControlTemplate TargetType="{x:Type ListBoxItem}">   <CheckBox Command="{Binding SelectedItemCommand, Mode=OneWay, Source={StaticResource comd}}">   <CheckBox.CommandParameter>   <MultiBinding Converter="{StaticResource cv}">   <Binding ElementName="" Path="Content"/>   <Binding ElementName="" Path="IsChecked"/>   </MultiBinding>   </CheckBox.CommandParameter>   <ContentPresenter></ContentPresenter>   </CheckBox>   </ControlTemplate>   </Setter.Value>   </Setter>   </Style>   </Setter.Value>   </Setter>  </Style> 

And its implementation is

Ultimately my aim is to be able to display all the selected items Text Content (Countries in this case) in a text box were each country is separated by a comma. The only thing I am currently missing is the Country. I would be grateful for any assistance.
