How to edit fileupload control in Gridview without clearing all other fileupload controls?

I'm tasked with creating a asp.net website that will allow a user to submit names and pdf documents for people on their project.  For each person there needs to be 4 fileupload controls.  I was trying to do this with a gridview, but everytime I edit a row and update all the fileupload controls clear out.

 

I'm using C#, .net 4.7.2

 

ASP.NET (Classic)

    Here's an example:

    <%@ Page Language="C#" %>
<%@ Import Namespace="System.IO" %>
<script type="text/c#" runat="server">    protected void BtnUpload_Click(object sender, EventArgs e)
    {
        if (Request.Files != null)
        {
            foreach (string file in Request.Files)
            {
                var uploadedFile = Request.Files[file];
                if (uploadedFile.ContentLength > 0)
                {
                    var appData = Server.MapPath("~/app_data");
                    var fileName = Path.GetFileName(uploadedFile.FileName);
                    uploadedFile.SaveAs(Path.Combine(appData, fileName));
                }
            }
        }
    }</script>
