We do not have support for the WinForms PDF viewer control in the ASP.NET(Classic). However, as a workaround we can use the ejPdfViewer control as in the below code snippet.

PdfViewerAPIController.cs
public class PdfViewerAPIController : ApiController { public object PostViewerAction(Dictionary<string, string> jsonResult) { PdfViewerHelper helper = new PdfViewerHelper(); helper.Load(Helper.GetFilePath("Barcode.pdf"));
object output = helper.ProcessPdf(jsonResult); string response = JsonConvert.SerializeObject(output); return response; } }
public class Helper { public static string GetFilePath(string path) { string _dataPath = GetCommonFolder(new DirectoryInfo(HttpContext.Current.Request.PhysicalApplicationPath)); _dataPath += @"\" + path; return _dataPath; }
static string GetCommonFolder(DirectoryInfo dtInfo) { var _folderNames = dtInfo.GetDirectories("Data"); if (_folderNames.Length > 0) { return _folderNames[0].FullName; }
return dtInfo.Parent != null ? GetCommonFolder(dtInfo.Parent) : string.Empty; } } |
