The LoadText method accepts a physical file, a FileStream, a string or a byte array to load documents into the web editor.

This sample shows how to load a document in the controller and pass it as a ViewModel to the view in order to load a document.

In the controller method Index, the document is loaded into a MemoryStream and then stored in the ViewModel Document that holds the document as a Base64 encoded string. This ViewModel is returned to the actual view.

public ActionResult Index()
{
    Document document = new Models.Document();

    MemoryStream ms = new MemoryStream();
    FileStream fs;

    // load the document into a stream
    using (fs = System.IO.File.OpenRead(
        Server.MapPath("/App_Data/documents/document.docx")))
    {
        fs.CopyTo(ms);
        document.BinaryDocument = Convert.ToBase64String(ms.ToArray());
    }
    
    // forward the document to the view
    return View(document);
}

In the view, the Base64 encoded string is converted back into a byte array and loaded using the LoadText method into the web editor.

@model tx_loadStream.Models.Document

@using TXTextControl.Web
@using TXTextControl.Web.MVC

@Html.TXTextControl().TextControl(settings => {
    settings.Dock = TXTextControl.Web.DockStyle.Window;
}
).LoadText(Convert.FromBase64String(Model.BinaryDocument),
  BinaryStreamType.WordprocessingML).Render()
