RadUpload not finding files with Radajaxmanager

Hello
I have a radupload inside radgrid as an itemtemplate. The uploader is used to save icon image in database along with other details. The grid has a checkbox whose autopostback is set on for checking checkChanged event accordingly. I have used radajaxmanager so that the page doesnot post back. But i face a problem when i try to save the uploaded image icon using radtoolbarbutton. Uploaded file show 0 count when i try to save the same as the page post back and there is no file to save. I have also added a client side function for disabling ajax on its clientclick of radtoolbarbutton but it results in an error of "Object doesn't support property or method 'set_enableAjax'". Please help me in achieving the required target without any code compromises.
Thanks in advance.

Latest version displays EmptyMessage instead of selected item

Hello,
I have a simple RadComboBox that when an item is selected it redirects the page back to itself and is supposed to display the item that was selected in the RCB.
This was working with Web.UI version 2010.3.1109.40, but it broke after upgrading to version 2011.3.1115.40.

With the latest version it will reload the page, but will display the "EmptyMessage" text instead of the selected text.

Here's my page:

<%@ Page Title="Home Page" Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb"

Inherits="RadComboBoxBug._Default" %>

<!DOCTYPE HTML />

<%@ Register TagPrefix="telerik" Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" %>

<html>

<head id="Head1" runat="server">

<title>RadComboBox Issues</title>

<link href="~/Styles/Site.css" rel="stylesheet" type="text/css" />

</head>

<body>

<form id="Form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server" />

<div class="page">

<div class="main">

<div style="margin: 10px; border: 1px solid #CCC; padding: 10px;">

<telerik:RadComboBox ID="RadComboBox2" runat="server" EnableLoadOnDemand="true" EmptyMessage="Select a Person"

AppendDataBoundItems="false" AutoPostBack="true" DataValueField="RecordID" DataTextField="Name"

ShowMoreResultsBox="true" EnableVirtualScrolling="false" MarkFirstMatch="true"

CausesValidation="False" OnClientDropDownOpening="onDropDownOpening" />

<asp:Label ID="lbl_SelectedPerson" runat="server" Style="margin-left: 15px" />

</div>

</form>

</body>

<script type="text/javascript">

function onDropDownOpening(sender) {

var attributes = sender.get_attributes();

if (attributes.getAttribute("DefaultItem") === "true") {

sender.requestItems("", false);

attributes.setAttribute("DefaultItem", "false");

}

</script>

</html>

...and the it's code-behind:

Imports Telerik.Web.UI

Public Class _Default

Inherits Page

Private Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load

If IsPostBack = False Then

Dim personID As String = Request.QueryString("PID")

If personID IsNot Nothing Then

RadComboBox2.SelectedValue = personID

RadComboBox2.Attributes.Add("DefaultItem", "true")

RadComboBox2.Items.Add(New RadComboBoxItem(String.Format("Person {0}", personID), CStr(personID)))

End If

End Sub

Private Sub Page_PreRender(sender As Object, e As System.EventArgs) Handles Me.PreRender

lbl_SelectedPerson.Text = String.Format("Selected Item: {0}", RadComboBox2.SelectedValue)

End Sub

Private Sub RadComboBox2_ItemsRequested(sender As Object, e As RadComboBoxItemsRequestedEventArgs) Handles RadComboBox2.ItemsRequested

RadComboBox2.DataSource = GetPeople()

RadComboBox2.DataBind()

e.EndOfItems = True

End Sub

Private Sub RadComboBox2_SelectedIndexChanged(sender As Object, e As RadComboBoxSelectedIndexChangedEventArgs) Handles RadComboBox2.SelectedIndexChanged

Response.Redirect(String.Format("/Default.aspx?PID={0}", e.Value))

End Sub

Private Function GetPeople() As List(Of Person)

Dim theList As New List(Of Person)

For i As Integer = 1 To 100

theList.Add(New Person() With {.RecordID = i, .Name = String.Format("Person {0}", i)})

Next

Return theList

End Function

Public Structure Person

Public Property RecordID As Integer

Public Property Name As String

End Structure

End Class

Does anybody know what's going on with this?

Thanks,
-Aaron

Skin error after upgrade

I've upgrade to latest ASP.NET AJAX version, after upgrade I get this error about for my WebBlue skin:

Telerik.Web.UI.RadFormDecorator with ID='FormDecorator1' was unable to find embedded skin with name 'WebBlue'. Please, make sure that you spelled the skin name correctly, or if you want to use a custom skin, set EnableEmbeddedSkins=false.

I checked I've added Telerik.Web.UI.Skins.dll as described in :

http://blogs.telerik.com/blogs/posts/11-11-15/separate-skin-assembly-in-radcontrols-for-asp-net-ajax-with-q3-apos-11.aspx

When I change skin to default the error disappears. Any helps?

Custom async handler: Need event before download finished

Hello,

The Process() method in custom async handlers is great. However, it is called only upon completed download of a file.

Is there a way to hook into an earlier handler event at the moment the download is initiated? The idea is that I would like to check whether the file is valid as early as possible. It looks bad to have the user wait for a 50MB upload only to tell at the end that the file cannot be uploaded (e.g. if it already exists).

Thank you,
Stephan

Quick Access Toolbar not working in some browsers

If the Quick Access toolbar is enabled for the RibbonBar then in all browsers except IE9 a javascript error occurs and prevents everything from working.
If I disable the QA toolbar all works fine.
The error occurs in the initialize method of the RibbonBarQuickAccessToolbarItem object.

I have attached a screenshot of the error as seen in the developer tools of Safari 5.

RADListBox transfer grouped item.

When I use the RADListBox with grouped items. Everything displays correctly until I perform a client side transfer from one listbox to another. The transfered items append to the bottom of the listbox and are not grouped. How can I transfer and have everything regroup client side.

<script type="text/javascript">

function onClientTransferred(sender, args) {

//alert("transfer from id:" + args.get_sourceListBox().get_id());
//alert("transfer to id:" + args.get_destinationListBox().get_id());

var fromList = args.get_sourceListBox().get_items();
var fromItem = args.get_item();
var fromItemAttributes = args.get_item().get_attributes();
var fromItemCat = fromItemAttributes.getAttribute("DataGroupField");
alert("from item cat:" + fromItemCat);

args.get_destinationListBox().trackChanges();
var toList = args.get_destinationListBox().get_items();
var toItem = args.get_destinationListBox().findItemByValue(args.get_item().get_value());
var toItemAttributes = toItem.get_attributes();
toItemAttributes.setAttribute("DataGroupField", fromItemCat);
toItem.attributes = toItemAttributes;

var index = fromList.indexOf(toItem);
toList.removeAt(index);
toList.insert(index, toItem);

alert("to item:" + toItem.get_text());
args.get_destinationListBox().commitChanges();

}
</script>
