Hi David,
Thank you for your question.
When an element's
Visibility is set to
Hidden, it continues to occupy its usual space, but it is not drawn on the control (e.g. it still participates in the layout). If you want to hide an element and free the space it occupies, you should set its
Visibility to
Collapsed:
I hope you find this useful. Feel free to write back if you have any further questions.
Kind regards,
