I use the following code: (returns an excel obviously)
ControllerContext.HttpContext.Response.ContentType = "application/ms-excel";
ControllerContext.HttpContext.Response.Write(sw.ToString());
ControllerContext.HttpContext.Response.End();
return View();
where sw is a StringWriter in which i create my excel structure(a table). So, sw.ToString() is a table and some tds contains values like 0001234. When i open the excel file i see in those tds 1234, with no zeroes. What must i do to see those zeroes?
