How to check and uncheck dynamically valued checkbox inside foreach lo

Question

I have a view which shows files from folder and the number of files may vary from user to user

I am dynamically creating checkbox and capturing its values based on filename for each row 

the code is as follows

<input type="checkbox" id="@files.Filevalues" name="@files.Filevalues" value="1" checked="checked" />

My controller is as follows this passes value to view

var getinfo = await _context.EmployeeBasicInformations.FindAsync(id);
ViewBag.empid = getinfo.EmployeeId;
var foldername = getinfo.EmployeeEmail;
string dirPath = Configuration["FolderPath:Document_Path"];
string path = Path.Combine(dirPath, foldername);
string[] folderpath = Directory.GetFiles(path);
List<EmpDoc> files = new List<EmpDoc>();
foreach (string folderpaths in folderpath)
{
    files.Add(new EmpDoc
    {
        Filename = Path.GetFileName(folderpaths),
        EmployeeId = getinfo.EmployeeId,

    }) ;
}
return View(files);

MyModel is as follows 

public int EmployeeId { get; set; }
public string? Form1{ get; set; }
public string? Form2 { get; set; }
public string? EnteredBy { get; set; }
public DateTime? EnteredDatetime { get; set; }
public string? UpdatedBy { get; set; }
public DateTime? UpdatedDatetime { get; set; }
public string? ValidatedBy { get; set; }
public string? Form3 { get; set; }
public string? Form4 { get; set; }
public string? Form5 { get; set; }

[NotMapped]
public IFormFile File { get; set; }

[NotMapped]
public string Filename { get; set; }

[NotMapped]
public string Filevalues { get; set; }

the files are stored as form1.pdf, form2.pdf

when i check a checkbox for example if i am checking form1 checkbox , in db under form1  column i am saving it as 1 and 0 for non checked .

I am able to save the data, but i am facing issue when i relogin the page , i am unable to retrieve the values and pass it to view

my view is as follows 

@foreach (handbook.Data.EmpDoc files in Model)
{
    @if (files.Filevalues == "1")
    {
        <tr style="text-align:center;">
            <td>
            <input type="checkbox" id="@files.Filevalues" name="@files.Filevalues" value="1" checked="checked" />

            </td>
            <td>@files.Filename</td>
            <td class="text-nowrap">@Html.ActionLink("Download", "DownloadFile", new { fileName = files.Filename, id = files.EmployeeId })</td>
        </tr>
    }
    else 
    {
        <tr style="text-align:center;">
            <td>
               <input type="checkbox" id="@files.Filevalues" name="@files.Filevalues" value="0" />
            </td>
            <td>@files.Filename</td>
            <td class="text-nowrap">@Html.ActionLink("Download", "DownloadFile", new { fileName = files.Filename, id = files.EmployeeId })</td>
        </tr>
    }
}
