Note that the size of the maximized tile depends on the remaining space after the minimized tiles are measured and arranged. For example, if you the RadTileView control is 100 pixels wide and the MinimizedColumnWidth is set to 30px, the maximized item will be stretched over the renaming 70 pixels. You can control the width of the maximized item by setting the tileview's MinimizedColumnWidth. This will resize the minimized area and the also the maximized item.
I hope this information is useful.
