Rename images in server in Vue Rich text editor component

By using the insertImageSettings property, you can specify the server handler to upload the selected image. Then you can bind the imageUploadSuccess event, to receive the modified file name from the server and update it in the Rich Text Editor’s insert image dialog.

To configure the server-side handler, refer the below code.

[AcceptVerbs("Post")]
public void Rename()
{
    try
    {
        var httpPostedFile = System.Web.HttpContext.Current.Request.Files["UploadFiles"];
        imageFile = httpPostedFile.FileName;
        if (httpPostedFile != null)
        {
            var fileSave = System.Web.HttpContext.Current.Server.MapPath("~/Images");
            if (!Directory.Exists(fileSave))
            {
                Directory.CreateDirectory(fileSave);
            }
            var fileName = Path.GetFileName(httpPostedFile.FileName);
            var fileSavePath = Path.Combine(fileSave, fileName);
            while (System.IO.File.Exists(fileSavePath))
            {
