Speed of opening document from local

[Lim Ze Dong]

Hi there,

I found that when loading/opening a document from my local disk into the document editor, it takes some time, depending on the file size.

If it is a larger file, it will take longer time to load, but if it is a small file, then it will load very fast.

So I wonder if there is any way to make it faster? Maybe like I host it myself, is it possible? 

If yes then how can I do it?

Thanks.

Hi Lim, 

You can avoid the time delay whenever file upload, you can access the file directly from server side in APP Data folder. Kindly check below code snippet.  

Note: Client side you need to pass filename which document you want to open. 

Code Snippet: 

Client Side: 

loadFile(fileName: string) { 

    var obj = this; 

    var params = "{fileName: '" + fileName + "'}"; 

    var httpRequest = new XMLHttpRequest(); 

    httpRequest.open('Post', 'http://localhost:62870/api/DocumentEditor/Import?fileName=' + fileName, true); 

    httpRequest.setRequestHeader("Content-Type", "application/json"); 

    httpRequest.onreadystatechange = function () { 

      if (httpRequest.readyState === 4) { 

        if (httpRequest.status === 200 || httpRequest.status === 304) { 

          //Load Sfdt string in to document editor 

          obj.container. documentEditor.open(JSON.parse(httpRequest.responseText)); 

 

        }  

        else { 

            // exception 

        } 

      } 

    }; 

    obj.container.documentEditor.documentName = fileName; 

    httpRequest.send(params); 

  } 

 

Server side: 

       public string Import (string filename)  

        {  

  

            string path = _hostingEnvironment.ContentRootPath + "\\App_Data\\" + filename + ".docx”.  

            Stream stream = System.IO.File.OpenRead(path);  

            stream.Position = 0;  

            WordDocument document = WordDocument.Load(stream, FormatType.Docx);  

            string json = Newtonsoft.Json.JsonConvert.SerializeObject(document);  

            stream.Dispose();  

            document.Dispose();  

            return json.  

        }  

Regarding: If it is a larger file, it will take longer time to load 

The DocumentEditor control keeps the entire text contents (text, images, tables, and all other supported elements along with its formatting) of the document and its corresponding information needed for rendering in main memory. In case of opening a Docx file, you may think the file size is small and DocumentEditor utilizes very large memory. Whereas it is a zip archive file with extension “docx”, DocumentEditor control internally decompress it and populate the content in the document object model utilizing remarkable main memory.  This is the behaviour of document load in documenteditor.So, DocumentEditor takes some time to load the larger document. 

Please let us know if you have any questions.
