Behavior

Anchor Vertically

Sets the location of the control in relation to the parent container. When the parent container changes size, the control may move or resize to maintain its position.

The options for vertically anchoring include:

  • None: The control's size and location are not affected when the container size changes.
  • Top: The distance between the top of the control and the top of the container remains fixed when the container size changes.
  • Bottom: The distance between the bottom of the control and the bottom of the container remains fixed when the container size changes.
  • Both: The distance from the top and bottom of the control from the top and bottom of the container remains fixed when the container size changes. This means that control is resized to maintain these fixed distances.

Anchor Horizontally

Sets the location of the control in relation to the parent container. When the parent container changes size, the control may move or resize to maintain its position.

The options for horizontally anchoring include:

  • None: When the parent container changes size, the control's size and location are not affected when the container size changes.
  • Left: The distance between the left edge of the control and the left side of the container remains fixed when the container size changes.
  • Right: The distance between the right edge of the control and the right side of the container remains fixed when the container size changes.
  • Both: The distance from the left and right edges of the control from the left and right sides of the container remains fixed when the container size changes. This means that control is resized to maintain these fixed distances.
