我如何在Kendo网格中使用Input（file）？并将文件和数据从kendo网格一起发布到控制器

Question

我想在Kendo网格中使用输入文件，将数据和文件发布到控制器。 但是IFormFile为null，我无法保存文件。

我的模特。

public class LeadAttachmentViewModel
{
    public int LeadAttachmentId { get; set; }
    public IFormFile AttachTypeUrl { get; set; }
    public int AttachTypeId { get; set; }
    public Guid UniqueFileIdentifier { get; set; }
    public string MetaData { get; set; }

}

  <div class="k-rtl">
                        @(Html.Kendo().Grid<MkProject.Models.ViewModel.LeadAttachmentViewModel>
                            ()
                            .Name("gridLeadAttachment")
                            .Columns(columns =>
                            {
                            columns.ForeignKey(e => e.AttachTypeId, (SelectList)ViewData["AttachTypeList"]).EditorTemplateName("GridForeignKey").Title("نوع فایل").Width("70px");
                            columns.Bound(c => c.MetaData).Title("توضیحات").Width(190);
                            columns.Bound(e => e.AttachTypeUrl).EditorTemplateName("FileUpload1").Title("فایل").ClientTemplate("#:UniqueFileIdentifier#");

                            columns.Command(cmd => { cmd.Edit().Text("ویرایش"); cmd.Destroy().Text("حذف"); }).Title("ابزار");
