I found a lot of questions about how to resize the form when a child control resizes, but I\'m trying to do something much simpler (maybe so simple people don\'t even ask it
For me, anchoring works only if I set it to all four sides:
Anchoring: Top, Bottom, Left, Right
Setting anchoring just to Left, Bottom moves the whole object when the form is resized in bottom, left side. Setting all four sizes really resizes the object, when parent is resized.
