The reordering control consists of three grey, horizontal lines on the right side of the cell. Dragging this control causes the entire cell to be moved to another position in the table.

The reordering control only appears if this property is set and the UITableViewSource.MoveRow(UITableView, Foundation.NSIndexPath, Foundation.NSIndexPath) method has been implemented on the UIKit.UITableViewSource. The reordering control can be selectively hidden on specific rows by returning false from UITableViewSource.CanMoveRow(UITableView, Foundation.NSIndexPath)
