Question

I have a list of items displayed as a ListBox.

<ListView ItemsSource="{Binding ListOfSomeItems}">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
            <GridViewColumn Header="Status">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <CheckBox IsChecked="{Binding IsReceived}" />
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>

Now there is 2 user cases I need to implement:

1) When user mark an Item as received (the CheckBox get checked) I need to update the item. How should I bind the checked event to ICommand in my ViewModel?

2) When user tries to remove received flag (un-checks the checkBox) a pop up should be provided with an option to cancel the operation (if someone clicked the checkBox by accident) or to provide a note for a reason. That note along with the Item that been unchecked should be sent to different ICommand in VM.

Any suggestions?

Thanks in advance

UPDATE:
My viewModel do implements INoftiyPropertyChanged but I do not have property for the single item. The property is nested in complex class: something like Account.Holders[x].Requirements[y].IsReceived.

Answer 1

1. Why just not bind a command which should be exposed by ViewModel:

<CheckBox 
     Command="{Binding ReceivedStatusChangedCommand}"
     CommandParameter="{Binding ...IsReceived}"
/>

Then in command handler you can analyze passed in value of the IsReceived as command parameter.
