my code behind :

Code:
if (fupImage.PostedFile.FileName != "")
            {
                if (!Utitlties.Instance.CheckImageFileType(fupImage.PostedFile.FileName))
                {
                    lblMessageForfupImage.Visible = true;
                    lblMessageForfupImage.Text = "Image file only accept *.jpg, *.png, *.bmp, *.gif Extensions !";
                    fupImage.Focus();
                }
                else
                {
                    evt.ImageURL = Utils.Instance.SaveImage(fupImage.PostedFile.InputStream, fupImage.PostedFile.FileName, true);
                    UniqueDesign.Utilities.Utitlties.Instance.DeleteFile(imgURL.ImageUrl);
                }
            }

when i debbuged it, it's HasFile properties return alway is false, and

fupImage.PostedFile.ContentLength = -2 but it still got filename and filetype.

here is my web.config :
