Akshaya    --! URGENT !--Hi Akshaya,We reviewed the link you have provided and when we uploaded the PDF files and those are displaying properly. In our case, we are loading the PDF file from the Azure Blob storage. Please find the attached files and try to re-produce the issue and let us know.

Hi Christiaan ,   
 
Thank you for your update.   
 
Based on the provided details, we suspect that the reported issue is due to position of the stream in the load method. So, can you add the below highlighted line in the load method of the controller class.    
 




[System.Web.Mvc.HttpPost]   
        public ActionResult Load(jsonObjects jsonObject)   
        {   
            PdfRenderer pdfviewer = new PdfRenderer();              
            MemoryStream stream = new MemoryStream();   
            var jsonData = JsonConverter(jsonObject);   
            object jsonResult = new object();   
            if (jsonObject != null && jsonData.ContainsKey("document"))   
            {   
                if (bool.Parse(jsonData["isFileName"]))   
                {   
                    string documentPath = GetDocumentPath(jsonData["document"]);   
 
                    if (!string.IsNullOrEmpty(documentPath))   
                    {   
                        byte[] bytes = System.IO.File.ReadAllBytes(documentPath);                         
                        stream = new MemoryStream(bytes);   
                    }   
                    else   
                    {   
                        string fileName = jsonData["document"].Split(new string[] { "://" }, StringSplitOptions.None)[0];   
                        if (fileName == "http" || fileName == "https")   
                        {   
                            var WebClient = new WebClient();   
                            byte[] pdfDoc = WebClient.DownloadData(jsonData["document"]);   
                            stream = new MemoryStream(pdfDoc);   
                        }   
                        else   
                        {   
                            return this.Content(jsonData["document"] + " is not found");   
                        }   
 
                    }   
                }   
                else   
                {   
                    byte[] bytes = Convert.FromBase64String(jsonData["document"]);   
                    stream= new MemoryStream(bytes);                       
                      
                }   
            }   
stream.Position = 0;    
            jsonResult = pdfviewer.Load(stream, jsonData);   
            return Content(JsonConvert.SerializeObject(jsonResult));   
        }   
 
If you are still facing the issue, can you provide the sample, code snippet for loading the document from Azure blob, format of the PDF document(base64 string/stream) which you are loading and the replication procedure. So that would be helpful for us to analysis more and assist you better.
