Dear,
I add new custom attribute to RadTreeNode using the following code:

Nod.Attributes.Add("Key", "Value")
Where Nod is a RadTreeNode, the attributes is added (Node attributes count is increased) but when I retrieved its value using: Nod.Attributes(Key) I always got Nothing.
Best Regards

starnge behavior with multi-select combobox

I have a multi-select combobox defined on my page with checkboxes and radio buttons in the template.
I am observing a strange behavior with the dropdown.
To close the dropdown I have to click outside of the combo.
On my save I pop-up a radalert that says that data is saved. If the user checks something in the combo and directly clicks save without clicking out anywhere on the form the pop-up takes two clicks to close. If I again repeat the same steps it increments another click till the time i refresh the page.

combo declaration:

<telerik:RadComboBox runat="server" ID="RadComboBoxParticipants" EnableLoadOnDemand="false"

Width="350px" OnPreRender="RadComboBoxParticipants_PreRender" AllowCustomText="true"

LoadingMessage="loading.." OnClientSelectedIndexChanging="OnClientSelectedIndexChanging" CloseDropDownOnBlur="true"

OnClientDropDownOpening="OnClientDropDownOpening" OnClientDropDownClosing="OnClientDropDownClosing"

OnClientBlur="OnClientBlur" OnItemDataBound="RadComboBoxParticipants_ItemDataBound">

<ItemTemplate>

<table>

<tr>

<td>

<asp:CheckBox ID="CheckBox1" runat="server" onclick="stopPropagation(event, this);"

ToolTip="Adds as option" />

</td>

<td>

<asp:RadioButton ID="RadioButton1" runat="server" GroupName="Type" onclick="SetUniqueRadioButton();"

ToolTip="Sets as default" />

</td>

<td>

<%# DataBinder.Eval(Container.DataItem,"FullName") %>

</td>

</tr>

</table>

</ItemTemplate>

<CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>

</telerik:RadComboBox>

Javascript:

var supressDropDownClosing = false;

function OnClientDropDownClosing(sender, eventArgs) {

eventArgs.set_cancel(supressDropDownClosing);

}

function OnClientSelectedIndexChanging(sender, eventArgs) {

eventArgs.set_cancel(supressDropDownClosing);

}

function OnClientDropDownOpening(sender, eventArgs) {

supressDropDownClosing = true;

}

function OnClientBlur(sender) {

supressDropDownClosing = false;

sender.toggleDropDown();

}

function stopPropagation(e, chk) {

e.cancelBubble = true;

if (e.stopPropagation) {

e.stopPropagation();

}

This is very annoying for the client. Can you suggest something.

ConvertToXhtml ContentFilter converts &nbsp to space

I'm currently using version 2009.1.527.35 of the Telerik RadControls for ASP.NET Ajax. When I use the Default Content Filters ( or none) and the user edits the content using the HTML view and adds an   then clicks Design and back to HTML, the entity is translated to a space. I narrowed down the issue to the the ConvertToXhtml content filter by a process of elimination.

Is this expected behavior? I did notice that Firefox doesn't exhibit the same behavior--only IE 8. I didn't try IE7 or Chrome.

I don't really care for the result--I'd like to keep XHTML formatting, but I don't really have a choice since the   is more critical to the CMS.

Here's how to reproduce the issue:

1) Create a page with the following markup:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="WebpPrototype._Default" %>

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<div>

<telerik:RadEditor ID="RadEditor1" runat="server" Skin="Black" ContentFilters=

"ConvertToXhtml,RemoveScripts,FixUlBoldItalic,IECleanAnchors,FixEnclosingP,MozEmStrong,ConvertFontToSpan,IndentHTMLContent,OptimizeSpans"

>

</telerik:RadEditor>

</div>

</form>

</body>

</html>

2) View the page in the browser. Click HTML. Add an   to the content. Click design. Click back and the &NBSP; has been replaced with spaces.
3) In the page markup, remove the ConvertToXhtml form the ContentFilters. Repeat and see the expected results.

Javascript OnLoad Format Stripper Not Supported

Hi I am using version 7.1.1.0 of the Ajax RadEditor and cannot upgrade. I need to strip out all Word tags and HTML with the exception of bold, italic, underline and some special characters like trademark, and copywright.

I added the following javascript from the documentation so I can strip the tags on the sumbit :

function OnClientLoad(editor, args)

{

editor.add_submit(function ()

{

editor.fire('SelectAll');

editor.fire('FormatStripper', {value : 'WORD'});

alert(editor.get_html());

});

}

</script>

when the page loads I receive the following javascript alert:
"Exception while exeduting client event OnClientLoad Error:Object doesn't support this property or method"

Again all I need to do is remove all word tags, script, span, and div tags.

unable to hide redorder buttons

I have a listbox used for reordering. IN the aspx page it is defined thus:

<

telerik:RadListBox ID="RadListBox1" runat="server" AllowReorder="True"

AppendDataBoundItems="True" DataSourceID="SqlDataSource1" DataTextField="Input"

DataValueField="TestTakerOrderID" EnableDragAndDrop="True" Font-Size="Medium"

Width="360px" >

</telerik:RadListBox>

From everything I can gather the "Showrerder="false" should hide the reorder buttons; thus allowing only drag and drop. That is not the case. The buttons always appear. How can I not show them but still allow drag and drop reordering?

RadGrid Drag and Drop feature: why so complicated!!

Hi,

I need to use the drag and drop feature of the RadGrid, so I checked out the demo (http://demos.telerik.com/aspnet-ajax/grid/examples/programming/draganddrop/defaultcs.aspx). Unfortunately, the way Telerik demostrates how to use this feature is not suitable for my situation. The following are the main two reasons (staying in the demo context: shipped and pending orders):

Telerik uses the Session variable to store the shipped and pending orders. In my case multiple pages will be opened; a user will open pages to view and compare the different orders. Therefore, storing the orders in the session will not work since when a row is dragged both windows will be affected by the changes upon postback.
On Row drop event, Telerik retreives the entities again, then inserts and deletes the dragged items from the entities's collection and afterwards, rebinds the grids. I don't understand why this has to be done this way. Why can't we manipulate the GridDataItems instead? We would just have to moved the GridDataItems, no need to retrieve the data source again and play around with the data source. Furthermore, in my scenario, the rows in the grid are added dynamically by the user. When a row is added, it is not yet saved in the database, the new records added to the RadGrid and the data will only be saved in the database when the user clicks "save". Playing with the entities's collection will not work in this case since it is not yet aware of the new rows added...

With all this being said, how can I implement the drag and drop feature to properly fit my scenario? Maybe having the drag and drop feature only client side, that would probably work...

Here's a short example of what I wish to acheive (server side):

<h2>Pending Orders</h2>

<telerik:RadGrid runat="server" ID="grdPendingOrders" OnNeedDataSource="grdShippedOrders_NeedDataSource" OnRowDrop="grdShippedOrders_RowDrop" AllowMultiRowSelection="true">

<MasterTableView DataKeyNames="OrderId">

<Columns>

<telerik:GridDragDropColumn Visible="false" />

</Columns>

</MasterTableView>

<ClientSettings AllowRowsDragDrop="True">

<Selecting AllowRowSelect="True" EnableDragToSelectRows="false" />

</ClientSettings>

</telerik:RadGrid>

<h2>Shipped Orders</h2>

<telerik:RadGrid runat="server" ID="grdShippedOrders" OnNeedDataSource="grdShippedOrders_NeedDataSource" OnRowDrop="grdShippedOrders_RowDrop" AllowMultiRowSelection="true">

<MasterTableView DataKeyNames="OrderId">

<Columns>

<telerik:GridDragDropColumn Visible="false" />

</Columns>

</MasterTableView>

<ClientSettings AllowRowsDragDrop="True">

<Selecting AllowRowSelect="True" EnableDragToSelectRows="false" />

</ClientSettings>

</telerik:RadGrid>

protected void grdShippedOrders_RowDrop(object sender, GridDragDropEventArgs e)

{

foreach (var item in e.DraggedItems)
