Tiles can display one or several images. An image can be specified in the Tile using its Image, ImageKey, or Symbol properties. Also, it can be specified as a part of the template's ImageElement or stored in one of the CommonImage objects that belong to C1TileControl.
There are a few tricks when working with images. For example, you can create a big image that consists of N images in width and M images in height. If so, the ImageColumns property must be set to N, and ImageRows property must be set to N. Also, the ColumnIndex and RowIndex properties can be used to pick a small image from large matrix.
The ImageList collection should be specified first in order to use the ImageIndex property.
