DocumentEditor depends on server side interaction for below listed operations can be written in ASP.NET Core using Syncfusion.EJ2.WordEditor.AspNet.Core.
Note: Syncfusion provides a predefined Word Processor server docker image targeting ASP.NET Core 2.1 framework. You can directly pull this docker image and deploy it in server on the go. You can also create own docker image by customizing the existing docker project from GitHub. To know more, refer this link.Word Processor Server Docker Image Overview
This section explains how to create the service for DocumentEditor in ASP.NET Core.
Word documents can be imported to DocumentEditor using the below code snippet.
[AcceptVerbs("Post")]
[HttpPost]
[EnableCors("AllowAllOrigins")]
[Route("Import")]
public string Import(IFormCollection data)
{
if (data.Files.Count == 0)
return null;
Stream stream = new MemoryStream();
IFormFile file = data.Files[0];
int index = file.FileName.LastIndexOf('.');
string type = index > -1 && index < file.FileName.Length - 1 ?
file.FileName.Substring(index) : ".docx";
file.CopyTo(stream);
stream.Position = 0;
WordDocument document = WordDocument.Load(stream, GetFormatType(type.ToLower()));
string json = Newtonsoft.Json.JsonConvert.SerializeObject(document);
document.Dispose();
return json;
}Paste with formatting action is defined in the below code snippet.
[AcceptVerbs("Post")]
[HttpPost]
[EnableCors("AllowAllOrigins")]
[Route("SystemClipboard")]
public string SystemClipboard([FromBody]CustomParameter param)
{
if (param.content != null && param.content != "")
{
try
{
WordDocument document = WordDocument.LoadString(param.content, GetFormatType(param.type.ToLower()));
string json = Newtonsoft.Json.JsonConvert.SerializeObject(document);
document.Dispose();
return json;
}
catch (Exception)
{
return "";
}
}
return "";
}
public class CustomParameter
{
public string content { get; set; }
public string type { get; set; }
}Restrict editing action is defined in the below code snippet.
[AcceptVerbs("Post")]
[HttpPost]

public string[] RestrictEditing([FromBody]CustomRestrictParameter param)
{
if (param.passwordBase64 == "" && param.passwordBase64 == null)

}
public class CustomRestrictParameter
{
public string passwordBase64 { get; set; }
public string saltBase64 { get; set; }
public int spinCount { get; set; }
}Spell check action is defined in the below code snippet.

[EnableCors("AllowAllOrigins")]
[Route("SpellCheck")]
public string SpellCheck([FromBody] SpellCheckJsonData spellChecker)
{
try
{
SpellChecker spellCheck = new SpellChecker(spellDictionary);
