    Hi, using an example from a different forum thread, I was able to use the async upload with a controller that saves the documents like so:


        async: {
            saveUrl: "api/document",
            removeUrl: "api/destroyDocument",
            autoUpload: true


    Upload (in vb):

        Public Async Function UploadDocument() As Task

            Dim root As String = HttpContext.Current.Server.MapPath("~/App_Data")
            Dim provider = New MultipartFormDataStreamProvider(root)


                Await Request.Content.ReadAsMultipartAsync(provider)
                For Each file As System.Net.Http.MultipartFileData In provider.FileData
                    Dim fileInfo As FileInfo = New FileInfo(file.LocalFileName)
                    If System.IO.File.Exists(file.LocalFileName) Then
                        FileIO.FileSystem.RenameFile(file.LocalFileName, Replace(file.Headers.ContentDisposition.FileName, """", ""))
                    End If

            Catch ex As Exception

            End Try

        End Function

    Which works fine. However, while I've declared the Remove function (based on the sample service example for the upload), it doesn't have any information in the files() even though the remove button properly hits the function:


       Public Function RemoveDocument(ByVal fileNames As String()) As ActionResult


    There's nothing in the fileNames variable and seemingly nothing in the Request.Content. How can I get the list of files I'm trying to delete?

    Hello Bryan,

    The provided sample code looks correct. If the issue is still reproducing, you could send us an isolated runnable example here or in a support ticket, so we are able to inspect it.
