As the error indicates, you simply can't do this. I'd imagine its a security feature, as the inputFile is allowing uploading of a file from the user's computer. You could use an iframe to contain the input file component, which means that other frames would be unaffected, but from the technical point of view it has to be a full refresh of the containing page.

hi bob.cant we use input type="file",HTML tag – Pankaj Feb 4 at 12:01
No, as this will be regular HTML form rather than a Visualforce form, so the file won't be bound to anything on the controller side. – Bob Buzzard Feb 4 at 12:49
