No Files Returned to Controller

[Arie]

 

We are currently working with the Upload control in what would seem to be a very simple setup.

@(Html.Kendo().Upload()
                            .Name("files")
                            .ShowFileList(false)
                            .Multiple(false)
                            .Async(a => a
                                 .Save("Save", "Patient")
                                 .AutoUpload(true)
                                 .SaveField("files")
                              )
                            .Validation(validation => validation.AllowedExtensions(new string[] { ".gif", ".jpg", ".png" }))
                              )

 

 

and our controller is defined as such

[HttpPost]
public async Task<IActionResult> Save(IEnumberable<HttpPostedFileBase> files)

 

What is happening is that the files parameter is not null but has a count of 0. This is in an ASP.NET core MVC app.

What could the issue be? Is there something simple we are missing here?

Thanks
AJ

Hello Arie,

This issue often occurs because the name of the widget doesn't match the name of the parameter received by the controller, but they match in your case so we're good on that front.

I noticed that instead of IEnumerable you're setting the type as IEnumberable, with an extra B; let's fix that and see if the problem keeps occurring.

Thank you.

That's just a typo. Yes the problem is still present.

 

I have also tried List but it has the same problem.

Hi Arie,

In order the Upload to work properly, the HttpPostedFileBase class should implement the Microsoft.AspNetCore.Http.IFormFileinterface.

Also, you may have to return an ActionResult, instead of the asynchronous Task<IActionResult>:

public ActionResult Save(IEnumberable<HttpPostedFileBase> files)
