I have a ListView in a StackPanel and when I set the ItemSource property on the ListView it in the code-behind, the height of the ListView becomes taller that StackPanel, and it make the ListView chopped off at the bottom of the StackPanel.

I did not hard-code the height of the ListView, but I thought the default behavior was that the last control in a StackPanel automatically fills the rest of the StackPanel height?

If I hard-code a height in the XAML, it does fine, but I do not want to hard-code height.

What am I missing?
