[Solved] multiple upload controls in grid do not work

[Sorina]

Hi,
I need to have a grid where for each row I should have an upload control.

The code looks like:

 columns.Template(o =>
            {%>
               <%=Html.Telerik().Upload()
               .AssetKey(o.Course.Aktivitetskode)                             
                .Name("attachments")
                .Multiple(true)
                .Localizable("Da")
                .HtmlAttributes(new { @class = "myCustomClass"})               
                .Async(async => async
                    .Save("Save", "Enrollment", new {folderPath = o.Documentation.FolderPath, courseActivityCode=o.Course.Aktivitetskode })
                    .Remove("Remove", "Enrollment", new { folderPath = o.Documentation.FolderPath })
                    .AutoUpload(true)
                )%>
            <% });

The Save method signature looks like:

 public ActionResult Save(IEnumerable<HttpPostedFileBase> attachments, string folderPath, string courseActivityCode)

The upload works fine for the first upload control, but when I press on the second, after I select the files, nothing happens.
I figured out that this is due to the fact that all the controls get generated with the same name and id.
If I change the name of the upload control from .Name("attachments") into .Name("attachments" + counter++), when the save method gets invoked, the attachments is set to null, so I cannot retrieve the files. If I create a Save method for each row, with the first parameter named exactly as each upload control, it works, but I do not have a fixed max number of rows, so this is not a solution.

How shall I implement it to get it working?

Cheers,
Sorina

Your problem is the name of the upload control. All your upload controls will have the same name, and therefore the same id, so only the first one will work. You need to change the name of the upload control for each output.

I'm currently stuck trying to do the same thing on editing of a row and having multiple upload fields.
