Ran across this issue: https://github.com/IgniteUI/ignite-ui/issues/2134#issue-938844956 and wondering if this issue affects the MVC helper as well?
With the file upload, I need to capture user input that is associated with the file. I have looked at https://www.igniteui.com/help/igupload-using-server-side-events, I have had no luck with passing the data, even the static text from the example does not come acorss.
I have the following in Application_Start()
Dim controlId As String = "igUploadProjectDocTypes" UploadProgressManager.Instance.AddStartingUploadEventHandler(controlId, AddressOf Controllers.ProjectDocumentsController.igUpload_UploadStarting) UploadProgressManager.Instance.AddFinishedUploadEventHandler(controlId, AddressOf Controllers.ProjectDocumentsController.igUpload_UploadFinished)
And both events are being called (breakpoints are hit)
Public Shared Sub igUpload_UploadStarting(sender As Object, e As UploadStartingEventArgs)
Public Shared Sub igUpload_UploadFinished(sender As Object, e As UploadFinishedEventArgs)
@(Html.Infragistics.Upload() _ .ID("igUploadProject") _ .Mode(UploadMode.Multiple) _ .MultipleFiles(True) _ .AutoStartUpload(False) _ .ProgressUrl(Url.Content("~/IGUploadStatusHandler.ashx")) _ .ControlId("igUploadProjectDocTypes") _ .Render() )
The alert for with `JQuery` does execute.
<script type="text/javascript"> $(function () { alert('jQuery'); $("#igUploadProject").on("iguploadonformdatasubmit", function (evt, ui) { alert('on(iguploadonformdatasubmit)'); $("#igUploadProject").igUpload("addDataField", ui.formData, { "name": "Parameter Name", "value": "Value" }); }); $("#igUploadProject").on("iguploadfileuploading", function (evt, ui) { alert('on(iguploadfileuploading)'); alert(ui.fileInfo.serverMessage); }); $("#igUploadProject").on("iguploadfileuploaded", function (evt, ui) { alert('on(iguploadfileuploaded) ' + ui.fileInfo.serverMessage); }); $("#igUploadProject").on("iguploadonerror", function (evt, ui) { // This property can be set during the // server event UploadStarting. If not set it’s // an empty string. (You can use it to display custom error messages.) alert(ui.serverMessage); }); }); </script>
Versions:Infragistics.Web.Mvc: 5.21.1.7IgniteUI: 21.1.11JQuery: 3.6.0
Update 2021-07-21
I switch to the jQuery version and the upload works:
<script type="text/javascript"> $(function () { $("#upload").igUpload({ mode: "single", autostartupload: false, controlId: "upload", useSingleRequest: true, progressUrl: "../../IGUploadStatusHandler.ashx" }); $("#upload").on("iguploadfileuploading", function (evt, ui) { alert('on("iguploadfileuploading"'); alert(ui.fileInfo.serverMessage); }); $("#upload").on("iguploadfileuploaded", function (evt, ui) { alert('on("iguploadfileuploaded"' + ui.fileInfo.serverMessage); }); $("#upload").on("iguploadonerror", function (evt, ui) { // This property can be set during the // server event UploadStarting. If not set it’s // an empty string. (You can use it to display custom error messages.) alert(ui.serverMessage); }); //$("#upload").on("iguploadonformdatasubmit", function (evt, ui) { // $("#upload").igUpload("addDataField", ui.formData, { "name": "Parameter Name", "value": "Value" }); //}); // Workaround: $("#upload").on("iguploadonformdatasubmit", function (evt, ui) { // switct form data parameters order var fileId = "upload_" + ui.fileId + "__frm_if"; var fileInfo = ui.formData.get(fileId); ui.formData.delete("upload_0__frm_if"); ui.formData.append("Parameter Name", "Value"); ui.formData.append(fileId, fileInfo); }); alert('jQuery'); }); </script>
<div id="upload"></div>
