ListBoxItem DataTemplate with HyperLink Problem

Kevin Marois

I have a listbox bound to an entity called NavigationItemEntity which displays hyperlinks as the list items: XAML

<ListBox.ItemTemplate>
    <DataTemplate>

        <TextBlock>

            <local:MaroisHyperlink LinkText="{Binding Caption}">
                                                
                <i:Interaction.Triggers>
                    <i:EventTrigger EventName="LinkClicked">
                        <i:InvokeCommandAction Command="{Binding RelativeSource={RelativeSource FindAncestor, 
                                                                    AncestorType={x:Type local:MaroisNavigationPane}}, 
                                                                    Path=ItemClickedCommand}"
                                                CommandParameter="{Binding Path=SelectedItem,ElementName=itemsList}"/>
                    </i:EventTrigger>
                </i:Interaction.Triggers>
                                                
            </local:MaroisHyperlink>
                                            

    </TextBlock>

    </DataTemplate>
</ListBox.ItemTemplate>

</ListBox>

Code behind

private ICommand _ItemClickedCommand;
public ICommand ItemClickedCommand
{
get
{
if (_ItemClickedCommand == null)
_ItemClickedCommand = new RelayCommand<NavigationEntity>(p => ItemClickedExecuted(p), p => ItemClickedCanExecute(p));
return _ItemClickedCommand;
}
}

private bool ItemClickedCanExecute(NavigationEntity args)
{
return true;
}

private void ItemClickedExecuted(NavigationEntity args)
{
RaiseItemClickedEvent(args.Id, args.ItemType);
}

The problem is that if I first don't click the list item, but just the link, then the link is sent as the command parameter. If I first click the list item, THEN click the link, then entity is passed, which is what I want. How can I force the list item to be selected when its link is clicked?

When you click the link, it doesn't select the item first, so the SelectedItem won't be what you're expecting. Try using:

CommandParameter="{Binding}"

That did it. Thanks

If it's not broken, fix it until it is. Everything makes sense in someone's mind. Ya can't fix stupid.
