Hi Ken,

Thanks for your response. I did try your suggestion,  but I got the same problem. The problem is that, my MVC is dynamic form. The form's elements are rendered from database, each element has its appropriate view, for example, element type button has its view button.cshtml, type input has its view input.cshtml and so on. When I tried to integrated Upload button to this form, whenever I clicked it, the submit event was automatically called, its controller's actions were not called. And that caused all the problems. Do you have any new approach?

Thanks,

Regards,
