Hello,

I want to use the files selected from the Upload control to populate a grid.

below is my code, please provide examples I had trouble following the documentation...It wasn't exactly what I wanted, I want the same interface of selecting documents that the upload control provides, but I want to make a collection of those documents and then set it as the datasource for my grid.

Here is my code:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default3.aspx.cs" Inherits="MultiFileUploadPrototype.Default3" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI, Version=2011.3.1305.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4" %>

function conditionalPostback(sender, eventArgs) {

if (eventArgs.get_eventTarget().match(theRegexp)) {

var upload = $find(window['UploadId']);

//AJAX is disabled only if file is selected for upload

if (upload.getFileInputs()[0].value != "") {

eventArgs.set_enableAjax(false);

}

function validateRadUpload(source, e) {

e.IsValid = false;

var upload = $find(source.parentNode.getElementsByTagName('div')[0].id);

var inputs = upload.getFileInputs();

for (var i = 0; i < inputs.length; i++) {

//check for empty string or invalid extension

if (inputs[i].value != "" && upload.isExtensionValid(inputs[i].value)) {

e.IsValid = true;

break;

}

var $ = $telerik.$;

function onClientFileUploaded(radAsyncUpload, args) {

// var $row = $(args.get_row());

// var categoryInputName = radAsyncUpload.getAdditionalFieldID("TextBox");

// var categoryInputType = "text";

// var categoryInputID = categoryInputName;

// var categoryInput = createInput(categoryInputType, categoryInputID, categoryInputName);

I have a class called uploadedDocument, which contains an ID, Name, Category and Subcategory. How do I on the server side create a collection of this type based on the documents selected (for example, the document name I would use for the Name property and empty string for the other properties).

Thanks,

Thanks!

Hey,

I was able to figure out the grid issue.

However I can't figure out how to hide the rows of uploaded documents in the UploadAsync control. I figured out how to add the files being uploaded into a grid control, but I can't figure out how to hide the rows being added to the UploadAsync control.

I have attached screenshots to demo what i have and what im trying to accomplish.

Screenshot 1 shows currently what I have. You click the select button and select the documents you want to upload, and the rows are added above the UploadAsync and also to the grid control.

Screenshot 2 shows what I want to accomplish. You click the select button and select the documents you want to upload and the rows aren't added to the UploadAsync control but just the grid.

Can this be accomplished?

Thanks
