The FlowLayoutControl arranges its items into rows or columns, according to the FlowLayoutControl.Orientation property. By default, the flow of items is automatically wrapped at the container’s edge. However, you can wrap the flow manually at a specific item. In the following image, the flow of items is automatically wrapped at Item 6, and manually at Item 9:
The following code snippet displays items in FlowLayoutControl and enables the maximization feature.

The FlowLayoutControl supports the following features:
Automatic and manual item flow wrapping.
To disable item flow wrapping use the FlowLayoutControl.BreakFlowToFit property. The FlowLayoutControl.IsFlowBreak attached property allows you to manually wrap the flow of items, starting a new column or row, at a specific item.
- Items can be stretched to the width/height of the FlowLayoutControl. See the FlowLayoutControl.StretchContent property.
- Dragging-and-dropping items, allowing an end-user to move items to new positions. See the FlowLayoutControl.AllowItemMoving property.
- Resizing layers using built-in layer separators. See the FlowLayoutControl.AllowLayerSizing property.
- Maximizing a specific item in the center of the FlowLayoutControl, while other items are arranged in a single layer (column or row) along the control’s edge. See the FlowLayoutControl.MaximizedElement property.
