Visibility.Collapsed Property - Only Collapses Horizontally?

I am using a Grid container with several controls. I have some logic to change the visibility of the controls.

If all the controls in a row are collapsed then the other fields move up as expected. However, if all the controls in a column are collapsed the fields do not move to the left as expected.

Is this expected behavior of the collapsed property?

Thanks
