Hello Mark,

I'm attaching a sample for your reference.

In the sample the "Index.cshtml" contains the igUpload configuration where the ID("upload1") and ControlId("upload1") are set in order to make the client-side and server-side event wiring. Also the onFormDataSubmit event is handled in order to send the additional data with the file upload to the server:

<script>

    $(function () {
        $("#upload1").on("iguploadonformdatasubmit", function (evt, ui) {
            $("#upload1").igUpload("addDataField", ui.formData, { "name": "Test Name", "value": "Test value" });
        });
    });

</script>

@Html.Infragistics().Upload().ID("upload1").ControlId("upload1").Render()

In "Global.asax" there is the server-side event wiring with this code:

UploadProgressManager.Instance.AddStartingUploadEventHandler("upload1", new EventHandler<UploadStartingEventArgs>(HomeController.igUpload_UploadStarting));

In the "HomeController.cs" there is the server-side "StartingUpload" event handler:

public static void igUpload_UploadStarting(object sender, Infragistics.Web.Mvc.UploadStartingEventArgs e)
{
    foreach (var dataField in e.AdditionalDataFields)
    {
        string fieldName = dataField.Name;
        string fieldValue = dataField.Value;
    }
}
