I am trying to understand how best to extend the ListBox control. As a learning experience, I wanted to build a ListBox whose ListBoxItem s display a CheckBox instead of just text. I got that working in a basic fashion using the ListBox.ItemTemplate , explicitly setting the names of the properties I wanted to databind to. An example is worth a thousand words, so... I've got a custom object for databinding: public class MyDataItem { public bool Checked { get; set; } public string DisplayName { get; set; } public MyDataItem(bool isChecked, string displayName) { Checked = isChecked; DisplayName = displayName; } } (I build a list of those and set ListBox.ItemsSource to that list.) And my XAML looks like this: <ListBox Name="listBox1"> <ListBox.ItemTemplate> <DataTemplate> <CheckBox IsChecked="{Binding Path=Checked}" Content="{Binding Path=DisplayName}" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> This works. But I want to make this template reusable, i.e. I'll want to bind to other objects with properties other than "Checked" and "DisplayName". How can I modify my template such that I could make it a resource, reuse it on multiple ListBox instances, and for each instance, bind IsChecked and Content to arbitrary property names?
