How to show button when the user clicks a listbox item?

Question

I was checking this window. It has a listbox, and when you click an item, it shows three buttons.

I want to implement something similar in my program. How can I do that?

Answer 1

You can bind to the IsSelected of the item, either by directly binding the Visibility using a BooleanToVisibilityConverter or by employing a DataTrigger .

1. Direct Binding

    <ListBox.Resources> <BooleanToVisibilityConverter x:Key="b2v"/> </ListBox.Resources> 

    <ListBox.ItemTemplate> <DataTemplate> <!-- ... --> <Button Visibility="{Binding IsSelected, RelativeSource={RelativeSource AncestorType=ListBoxItem}, Converter={StaticResource b2v}}".../> </DataTemplate> </ListBox.ItemTemplate> 

2. Style & DataTrigger

    throw new NotImplementedException();
