Each C1TileViewItem includes three different states – minimized, maximized, and the default state (which is neither minimized nor maximized). For example, in the following images all three of the C1TileViewItems in the C1TileView control appear in the default state:

In the following image, the red C1TileViewItem is maximized and the other two items are minimized:

When one item is maximized, the other items are minimized and appear as specified by the MinimizedItem property. The default state uses the Columns and Rows properties to determine the layout. The minimized/maximized states use the MinimizedItemsPosition property to determine layout.
