He just had the "NaN" problem I was talking about in other post.
I just replace them with "0.0", and all works.
A strange think I've seen is that if i add each layer and then I drag them up and down in the legend I've no problem, if I read an xml file and then I drag up and down layer in legend I've very strange effects (layer dosen't move).
May be the two things are the same problem ?
Is better I post there or on a codeplex ?
Thanks so much
