Tile dimensions and resizing

I am wondering, how to create a tile larger than its default size.
I have found the Devicebrowser TileWidth/Height properties, but even if I changed it to 300/300 it gives me just a stripe…like on the picture below…The columnspan doesnt change anything, as its managing columns…
Is there any way to create a larger tile? If not, how to create a more complex device/plugin, which will have several buttons, labels, images…


The TileWidth & TileHeight on the DeviceBrowser control determine the Tile size. If that isn’t working for you then that must mean you are doing something wrong.
