RadAjaxPanel not working after perform Excel Export

Hi all, i faced an issue which my radajaxpanel become not working after I clicked the excel export button.

Here is my spec:
1. Using RadAjaxPanel
2. Using ClientEvents-OnRequestStart="onRequestStart" to disable ajax
3. Using CommandItemTemplate and image button in it.
4. Using server-side method to export

Here is the problem:
1. Everything works fine before export excel
2. All the controls in RadAjaxPanel not working after perform the export action.
3. Found that there is no postback after i clicked the export button.

Here is my source code:
RadCodeBlock:

<telerik:RadCodeBlock runat="server" ID="RadCodeBlock1">

<script type="text/javascript">

function onRequestStart(sender, args) {

if ( args.get_eventTarget().indexOf("mngBtnExcel2") > 0) {

args.set_enableAjax(false);

}

function RowContextMenu2(sender, eventArgs) {

var menu = $find("<%=RadMenu2.ClientID %>");

var evt = eventArgs.get_domEvent();

if (evt.target.tagName == "INPUT" || evt.target.tagName == "A") {

return;

}

var index = eventArgs.get_itemIndexHierarchical();

document.getElementById("radGridClickedRowIndex").value = index;

sender.get_masterTableView().selectItem(sender.get_masterTableView().get_dataItems()[index].get_element(), true);

menu.show(evt);

evt.cancelBubble = true;

evt.returnValue = false;

if (evt.stopPropagation) {

evt.stopPropagation();

evt.preventDefault();

}

</script>

</telerik:RadCodeBlock>

Hide\Show Panel in master page from content page with strongly typed controls.

I'm having an issue updating content on a master page, using strongly typed controls.

On my master page, i have public classes that expose the .visible property of an asp.net panel, the content page sets the param to true or false. I have a radajaxmanager on master page and proxy on sub page, however I am unable to ajaxify the panels on the master.

For the solution I would prefer not to use FindControl()

Can someone point me in the correct direction?

[Solved] Add Vertical Separator "ON" RadToolBarSplitButton

Hi,

Some of our users are finding it difficult to grasp the difference between a RadToolBarSplitButton and a RadToolBarDropDown.
It seems that the subtle difference in the vertical offset of the dropdown arrow is not sufficient.

So, we'd like to add a thin vertical bar (like a separator) between the image and the dropdown arrow on the split button.
One solution that comes to mind is to add this bar to the image itself, but the image changes so we'd need to modify all of the images.

Is there some other technique that we could employ to accomplish this?

Thanks in advance for any advice.
