Question

int index = int.Parse(((Button)sender).CommandArgument);

BLL.Masters _objBll = new BLL.Masters();

var dir = @"D:\\madan\\30-08-2016\\MK_Alumni_Web\\MK_Alumni_Web\Resources\\Images\\" + CtrlTxtStudentID.Text;

if (!Directory.Exists(dir))

Directory.CreateDirectory(dir);

foreach (HttpPostedFile postedFile in FileUpload2.PostedFiles)

string fileName = Path.GetFileName(postedFile.FileName);

postedFile.SaveAs(Path.Combine(dir, fileName));
