AJAX Hover Menu problem

Hello,

I have a ASP.NET website that uses a master page that contains the navigation for the site. The navigation buttons are images. Some of the navigation button images have hover menus tied to them, using the MS AJAX Hover Menu Extender. Those hover menus contain several image buttons, so as to create a drop down menu affect. The problem I have is when any of the pages are loading all of my hover menu image buttons flash on the left side of the screen for a second or less as the page is being rendered, making it confusing for the user and unprofessional. Anyone ever deal with this, and can this be stopped?

Thanks,

Brian

I reviewed How to get the best answers as you suggested. I'm sorry johnwm, what do you suggest?

He suggests you give us a link to the page, or at least enough code to reproduce the problem so we may be able to help.

Otherwise, we are just guessing.

But if guessing we are, it seems to me your drop downs start out visible, and the are made invisible by the JS.
Perhaps if you set your menu's display or visibility to none from the CSS, you would not get the flash.

I have code like this and have tried display:none on the <div> and visible=false on the asp:panel. They do not flash on the screen when I do this, but then they do not become visible when the target control is hovered over. What would make them visible again when they need to be?

<cc1:HoverMenuExtender ID="HoverMenuExtender1" runat="server" TargetControlID="imgWedding" PopupControlID="pnlWeddingNav" PopupPosition="Bottom" OffsetX="6"> </cc1:HoverMenuExtender>


<div style=" position:relative; z-index:2;">

<asp:panel ID="pnlWeddingNav" runat="server">

<asp:ImageButton runat="server" ID="imbWeddingSales" ImageUrl="/Images/DropDownMenu/WeddingDDSales.jpg" AlternateText="" /><br />

<asp:ImageButton runat="server" ID="imbWeddingBridalShows" ImageUrl="/Images/DropDownMenu/WeddingDDBridalShows.jpg" AlternateText="" /><br />

</asp:panel>

</div>

What you will really have to do is

(a) send us a link to the page in question (best)
(b) give us the generated css and html (view source) of the page once it passes through the asp.net processor.

This way we will be able to see what the asp.net control does to show the menu and will be able to tell you what to fix.

Here is a link to the page


Here is the page source - note that the code I posted earlier was just a small sample of the entire page. Also, this is the page as I have originally built it, without the div display:none or asp:panel visible = false
