In wpf, I would like to implement a function, when you click an item of the listbox, and the left mouse button is pressed, the item can be narrowed 1/5 or 1/6, when the left button is released, this item can be reinstated the size, and the best situation is to achieve a DataTemplate or the Style. Any solution or ideas, thanks？
