          AllowMultiFileUpload="true" 
          @ref="MyUpload" >
</DxUpload>

<DxButton Text="Upload the First File" Click=OnButtonClick />

@code {
    bool UploadVisible { get; set; } = false;
    IEnumerable<UploadFileInfo> Files { get; set; }
    UploadFileInfo FirstFile { get; set; }
    DxUpload MyUpload { get; set; }

    protected void SelectedFilesChanged(IEnumerable<UploadFileInfo> files) {
        Files = files;
        UploadVisible = files.ToList().Count > 0;

        InvokeAsync(StateHasChanged);
    }

    void OnButtonClick(){
         FirstFile = Files.First();
         MyUpload.UploadFile(FirstFile);
    }
}

To upload the specified files or all files, use the UploadFiles or UploadAllFiles method, respectively.
