Hi,

I'm trying to implement the Mega Drop Down menu and in the same page display a RadGrid allowing filtering in the columns. It appears there is a bug in the Mega Drop Down, since filtering stop working in the RadGrid as soon I add the Mega Drop Down control. If I comment the Mega Drop Down code the RadGrid control works perfectly.

I use Q1 2012 version

Any clue??

Mega Drop Down code

<div id="MegaDropDown">

<script type="text/javascript">

function itemOpened(s, e) {

if ($telerik.isIE8) {

// Fix an IE 8 bug that causes the list bullets to disappear (standards mode only)

$telerik.$("li", e.get_item().get_element()).each(function () {

this.style.cssText = this.style.cssText;

});

}

</script>

<telerik:RadMenu runat="server" ID="RadMenu1" Skin="Sitefinity" OnClientItemOpened="itemOpened"

Width="590px" Height="50px" EnableShadows="true">

<telerik:RadMenuItem Text="Products" PostBack="false">

Hi!

After a couple of hours I found the problem/bug and the solution is very very simple but I think Telerik should fix it or warn about it!!

The Mega Drop Down menu use an external css file

<link rel="stylesheet" type="text/css" href="Style.css" />

and the style of the div that contain the Menu has a height property, well, if in your page you have, as me, a RadGrid below the Mega Drop Down menu, the height property (of the div of the Menu) will cover the RadGrid and will cause that you can't interact with the RadGrid and as in my case that the filters "stop" working.

div#MegaDropDown

{

margin: 0;

padding: 20px 0 0 0;

width: 880px;

height: 352px; /*the BUG!! */

background-image: url('Img/main_back.jpg');

background-repeat: no-repeat;

}

So, the solution is simple, delete the height property and all will work smoothly again!
