How to set initial files from model when using upload tag helper?

[Václav]

I would like to use the tag helper, but I cannot set the initial files like

<files>@Html.Raw(Model.InitialFiles)</files>

I am only able to set them as static HTML list, i.e.

<files><file name="dummy" size="1024" extension=".ext"/></files>

(https://docs.telerik.com/aspnet-core/tag-helpers/editors/upload/overview)

Is it possible to use the tag helper when the file list would be obtained from a model? And how?

Yes, this is not working for me also.  The statement:

.Files(
files =>
                      {
                              files.Add().Name("NAME1").Extension(".jpg").Size(1234);

                        }
                        )

Hello,

An exemplary .Files configuration of the Upload's taghelper is shown below:

<kendo-upload drop-zone="drop-zone1" name="files">
    <async save-url="save" />
    <files>
        @foreach (var f in Model)
        {
            <file name="@f.Name" extension="@f.Extension" size="@f.Size"></file>
        }
    </files>
</kendo-upload>

The index action returning the viewmodel:

 IList<UploadInitialFile> initialFiles = new List<UploadInitialFile>();

public IActionResult Index()
{
    UploadInitialFile file1 = new UploadInitialFile("file1", 1200000, ".jpg");
    UploadInitialFile file2 = new UploadInitialFile("file2", 1400000, ".png");

    initialFiles.Add(file1);
    initialFiles.Add(file2);

    return View(initialFiles);
}

The view model:

public class UploadInitialFile
{
    public string Name { get; set; }
    public long Size { get; set; }
    public string Extension { get; set; }

    public UploadInitialFile(string name, long size, string extension)
    {
        this.Name = name;
        this.Size = size;
        this.Extension = extension;
    }
}

For those that are having the same issue, I've created a how to article located here:  Kendo Upload 'Batch Mode'.

There is also source code to download, to get started quickly!
