WPF - adding item of different template in listview

Question

When item on my ListView is clicked I want to make another one of different template to appear below it. I have defined templates in Window.Resources and I thought about changing ItemTemplate when item is clicked, adding new item and changing it to default template, but i am using list with my ListView as ItemsSource it showed only one template and only because (for now) both of them are the same in bindings. What should i do?

Code:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        List<TransactionItem> item = new List<TransactionItem>();
        item.Add(new TransactionItem() { category="Deska", index="2", name="Topielec"});
        List<object> transactions = new List<object>();
        transactions.Add(new Transaction() { name = "Maciek", surname = "Chludzinski", begin = "Dzisiaj 20:14", end = "Dzisiaj 21:14", price = "240 zł", remain = "42 minuty", items = item });
        obMainListBinding.ItemTemplate = (DataTemplate)this.FindResource("LessClientTemplate");
        MessageBox.Show(obMainListBinding.ItemTemplate.DataTemplateKey.ToString());
        transactions.Insert(1, new Transaction() { name = "jhadf", surname = "Chludzhadfi", begin = "Dhad:14", end = "Dzisiajah", price = "240 zł", remain = "42 minuty"});
        obMainListBinding.ItemTemplate = (DataTemplate)this.FindResource("BasicTransactionTemplate");
        obMainListBinding.ItemsSource = transactions;

    }

    public class Transaction
    {
        public string name { get; set; }
        public string surname { get; set; }
        public string begin { get; set; }
        public string end { get; set; }
        public string remain { get; set; }
        public string price { get; set; }
        public List<TransactionItem> items { get; set; }
    }

    public class TransactionItem
    {
        public string category { get; set; }
        public string index { get; set; }
        public string name { get;set; }
    }

    public class LessTransaction
    {
        public string name { get; set; }
        public string surname { get; set; }
        public string begin { get; set; }
        public string end { get; set; }
        public string remain { get; set; }
        public string price { get; set; }
    }

}

Answer 1

You could try to use the ItemTemplateSelector property:

How do I use a ItemTemplateSelector together with a HeaderTemplate in a WPF ListView?

and(or) triggers that change Template:

How to change control template from Style.Triggers

EDIT

To use TemplateSelector you could add some dummy property on your items(or wrap them) that will allow you to discern new item from old.

...
public Int32 Generation
{
    get ...
}

public class GenerationTypeSelector : DataTemplateSelector
  {
    public override DataTemplate SelectTemplate(object item, DependencyObject container)
    {
        var transaction = (TransactionItem)item;
        if (transaction .Generation == 0)
            return Gen0Template;
        else
            return Gen1Template;
    }
  }
