Modify the sizing policy of containers

When as report element is in focus, arrow-shaped controls appear on the four sizing knobs located at the center of each side. These controls allow you to view and modify the sizing policy of a container.

Arrows pointing inward indicate a shrinking sizing policy: Arrows pointing outward indicate a maximizing policy:
  • X-Size="max" and Y-Size="max" or
  • X-Size-Adjustment="expandToParent" and Y-Size-Adjustment="expandToParent"
Click on an arrow to toggle its value.
