I want to use an ItemsControl with a ItemsSource. My issue is how to ensure that the items maintain their height ratio when displayed. Each time I resize the window, the items should resize accordingly, but their height ratio should remain constant. I want to display all items without using a scrollbar.

I’ve tried using a Grid with Height of RowDefinition set to star(x*) for each row. Obviously, this works well when the number of items is known in advance. However, since I need to use an ItemsSource, using RowDefinitions with an unknown number of rows is not feasible. Is there a way to achieve what I want? Thank you very much.
