is that a question?

sry....my mistake....how rotate camera on mouse move so that we can see the object from all side like arcball rotation....i also applied arcball rotation using quaternion....but i dnt know what's the prblm in that...i didn't make the exact rotation about mouse....if u want see my code...rply me

My technique is working perfectly fine in WPF but in DirectX, I dnt know whats the problem in that.

I haven't done that kind of thing while I was programming games. I think you could just rotate the object instead of rotating the whole camera. I'm not sure if it will be the same, but it's worth a try I guess.

Thanks for your help, but I don't want to rotate the object. Rotating camera instead of rotating object is same as the rotating object instead of camera.....we only have to calculate the exact rotation matrix. Thanks Bro...!!!
