urgnet: RadCombo inside updatepanel issue after .net 4.0 upgrade

Hi,
We're using telerik version 2009.2.826.35

We've just upgrade (from .net 3.5) to .Net 4.0 and asp.net 4.0
The Radcombo, sits inside asp undatepanel, postbacks after the selected item changes.
(Attaching the s-shot for the error) This is occuring after the results comes back from the server.

Becasue of this error, our submit button is not enabled(ie this is enabled from the server side code)
This was working fine with .net 3.5

Please treat this as an urgent issue.

Thanks for the help.

unhighlight items when unselected

I wish to use a single RadListBox as a replacement for a CheckBoxListControl. I am only really interested in the Checked functionality of the listbox items. Their selected state is irelevant. Therefore, I would like to prevent the items from ever being "Selected" and force users to use the checkboxes. I found a handy example which allows me to check/uncheck the checkboxes if the user clicks on an item by handling the selectedindexchanged event:

var sema_used;

function listItemClicked_BSC(sender, eventArgs) {

if (!sema_used) {

sema_used = true;

var item = eventArgs.get_item();

if (item.get_checked()) {

item.uncheck();

}

else {

item.check();

}

item.set_selected(false);

sema_used = false;

}

However, even though I call item.set_selected(false), the item still apears to be highlighted in the listbox. I believe this is probably because the selectedindex does not always change when a user clicks on an item. Is there a way to make sure all items are unselected (unhighlighted) in a listbox. Or is there a way to disable item selectiong, but keep the checkbox functionality? Ideally, there should be a client-side event for ItemClicked and ItemClicking, rather than just the current SelectedIndexChanged.

radTabStrip on new/close fire c# function

Looking for a way to store open tabs names in a database so they can be restored upon reopening in the event of a browser or computer crash.

I would like to use C# functions which would make or delete entries in the database when the user opens or closes a tab. Running into issues calling a C# function from JavaScript. Any idea's?

Also is there an option which would allow the user to reorder the tabs?

Thanks,

Geoff

[Solved] One checked node javascript problem

Hi,

I have a treeview inside a combobox, and i have hooked up a javasript that uncheckes any previus nodes, according to this article,
http://www.telerik.com/help/aspnet/treeview/tree_unchecknodebycheckinganothernode.html

But i cant get the script working, could it be becouse of the treeview being inside of a panelbar and/or a combobox, and if so, would anyone have a solution for this?

<asp:Content ID="Content3" ContentPlaceHolderID="phContent" Runat="Server">

<script type="text/javascript" language="javascript">

var oldNode;

function UpdateStatus(node)

{

if(oldNode != null)

{

oldNode.UnCheck();

}

node.Check();

oldNode = node;

}

</script>
