Hi Amin,  

Thank you for contacting Syncfusion support. 

Yes, we have provided tag helper support for FileExplorer component in version. Please refer to the below given release notes.  

From this version, you can manage images inside RichTextEditor using image browser as shown below 

   List<String> toolsList = new List<string>() { "images" }; 
    List<String> images = new List<string>() { "image" }; 
<ej-rte id="rteSample" width="820px" tools-list="toolsList"> 
            The Rich Text Editor(RTE) control is an easy to render in client side. Customer easy to edit the contents 
            and get the HTML content for the displayed content. A rich text editor control provides 
            users with a toolbar that helps them to apply rich text formats to the text entered 
            in the text area. 
    <e-image-browser extension-allow="*.png, *.gif, *.jpg, *.jpeg" file-path="/images/FileExplorerContent" ajax-action="@Url.Content("FileActionDefault")"> 
            <e-download url="/RichTextEditor/Download{0}"></e-download> 
            <e-get-image url="/RichTextEditor/GetImage{0}"></e-get-image> 
            <e-upload url="/RichTextEditor/Upload{0}"></e-upload> 
    <e-tools images="images"></e-tools> 

We have attached a sample for your reference which can be downloaded from the below link 

In RTE, image will be inserted based on the file path mentioned in image browser settings. In ASP Core, static files will be present in wwwroot folder and this path cannot be directly accessed in browsers while inserting image into RTE. So, we have included “wwwroot” in Controller page for FileExplorer actions alone. The following code represents the AJAX action in controller page for File Explorer window.  

        public FileExplorerOperations operation; 
        public RichTextEditorController(IHostingEnvironment hostingEnvironment) 
            this.operation = new FileExplorerOperations(hostingEnvironment.ContentRootPath); 
public ActionResult Upload(FileExplorerParams args) 
            operation.Upload(args.FileUpload, "/wwwroot" + args.Path); 
            return Json(""); 
        public ActionResult Download(FileExplorerParams args) 
            return operation.Download("/wwwroot" + args.Path, args.Names); 
        public ActionResult GetImage(FileExplorerParams args) 
            return operation.GetImage("/wwwroot" + args.Path); 
        public ActionResult FileActionDefault([FromBody] FileExplorerParams args) 
            var Path = "/wwwroot" + args.Path; 
                if (args.ActionType != "Paste" && args.ActionType != "GetDetails") 
                    var FilePath = operation.GetPhysicalPath(Path); 
                    if (!FilePath.ToLower().Contains("fileexplorercontent")) 
                        throw new ArgumentException(FilePath + "is not accessible. Access is denied."); 
                switch (args.ActionType) 
                    case "Read": 
                        return Json(operation.Read(Path, args.ExtensionsAllow)); 
                    case "CreateFolder": 
                        return Json(operation.CreateFolder(Path, args.Name)); 
                    case "Paste": 
                        return Json(operation.Paste(args.LocationFrom, args.LocationTo, args.Names, args.Action, args.CommonFiles)); 
                    case "Remove": 
                        return Json(operation.Remove(args.Names, Path, args.SelectedItems)); 
                    case "Rename": 
                        return Json(operation.Rename(Path, args.Name, args.NewName, args.CommonFiles)); 
                    case "GetDetails": 
                        return Json(operation.GetDetails(Path, args.Names)); 
                    case "Search": 
                        return Json(operation.Search(Path, args.ExtensionsAllow, args.SearchString, args.CaseSensitive)); 
                return Json(""); 
            catch (Exception e) 
                FileExplorerResponse Response = new FileExplorerResponse(); 
                Response.error = e.GetType().FullName + ", " + e.Message; 
                return Json(Response); 

Could you please let know if you need any further assistance on this?

Thanks Vinoth for reply, but your solution works only for ASP.NET Core JS1 (jQuery).

I want this solution for ASP.NET Core JS2 (Pure Javascript), and tag helpers in this solution doesn't work with JS2 (Pure JS). (There are completely different!)

e-image-browser & e-tools images tags doesnt' support ejs-richtexteditor.

Is there any solution for the problem?

When I click Insert Image, I have this window:

But I don't the window & need this one:
