the background of the control is grey with grid lines, the client wants it to be white - how to change this? i've changed every background setting i can find to white, but no joy.
it is definitely the control background not the map service image backgrounds. if i change the bottom map service to JPG it is no longer is transparent and is white, but every time you pan you see the grey with grid lines until the new image draws, which the client doesn't like.
i'm using 100% dynamic map services, there is no tiled layer.
i've attached a couple of pictures of what it looks like - one raw, one with some green circles illustrating the grid lines i'm talking about.
