Async Upload Posting to Wrong Method

[jim]

I am using .net core 3.5 and razor pages.   I have a file upload control that is calling OnPost even when the control explicitly says to call a different method name.

  @(Html.Kendo().Upload()
            .Name("files")
            .Multiple(false)
            .Async(a => a
                .Save("Async_Save", "New", new { Question = DebtorDropBox.Web.UI.Code.Question.DriversLicense })
                .AutoUpload(true)
            )
            .Events(e => e
                .Success("onSuccess")
                .Upload("onUpload")
                .Error("onError")
            )
            .Validation(validation => validation.AllowedExtensions(new string[] { ".jpg" }))
            .Validation(validation => validation.MaxFileSize(4000000))
        )

      for testing purposes I have added the following three methods to my page and no matter what It keeps calling OnPost.    Is there something I should be doing? 

        public async Task<ActionResult> Async_Save(IEnumerable<IFormFile> files, Question question)
        {
            return Page();
        }

        public async Task<ActionResult> OnPostAsync_Save(IEnumerable<IFormFile> files, Question question)
        {
            return Page();
        }

        public async Task<ActionResult> OnPost(IEnumerable<IFormFile> files, Question question)
        {
            return Page();
        }

Hello Jim,

Thank you for the provided code snippets.

Attached you will find a small project based demonstrating the Upload using both regular action methods and Page methods, which is currently commented out.

Let me know if you have any questions regarding the project. Feel free to modify it to demonstrate any issues you are experiencing.

Regards,
Martin
