The C1TileView.Columns and C1TileView.Rows properties get or set the number of columns and rows the C1TileViewItems are laid in respectively. If the value is zero, the minimum number that doesn't require scrolling is used. If both Columns and Rows are zero, the items are laid in a square.

The default state uses the Columns and Rows properties to determine the layout. The minimized/maximized states use the MinimizedItemsPosition property to determine layout. For more information about states, see TileViewItem States.
