Disable javascript generated by asp.net menu control

Question

I have a menu created using the asp.net menu control. I have added JQuery script that changes the display from pop-appearing to rolling out accordion style. However the pop-appearing still occurs, so what occurs overall is 'Mouse over Menu -> Sub Menu Appears --> Sub Menu Rolls back up'

What I am looking for, is a method to disable the javascript that asp.net generates that causes the sub menus to appear on mouse over, so that the replacement script that I have can function stand alone.

In other answers similar to this question I found the following:

public class MyCustomMenu : System.Web.UI.WebControls.Menu
{
    protected override void OnPreRender(EventArgs e)
    {
        // Don't call base OnPreRender
        //base.OnPreRender(e);
    }
}

However adding that to my masterpage.cs file did not solve the issue.

If you look at the HTML rendered by menu control you will see that every menu element has a function call on mouse over, called Menu_HoverStatic. To disable it simple include an empty function by the same name in your ASPX markup:

<script type="text/javascript">
   Menu_HoverStatic = function () { };
</script>

This will effectively disable original mouse over. Using this method you can disable other original event handlers if needed.

One thing that not everyone is familiar with is the use of Control Adapters to customize how a standard control renders.

Using adapters you can for example alter the output of the menu to be clean <ul> and <li> elements, integrate it with jquery, etc.

Here's an example of using ASP.NET 2.0 CSS Friendly Control Adapters on menues: http://www.asp.net/cssadapters/WalkThru/WalkThrough.aspx#SimpleMenu
