I wanna change the default menu-control for the navigation to a simple treeView-control.

I just replaced the menu-control with the TreeView-Control and attached the existing MenuSourceData to the TreeView-Control.

<asp:TreeView runat="server" DataSourceID="menuDataSource" ID="myTree" />
<asp:SiteMapDataSource runat="server" ID="menuDataSource" ShowStartingNode="false" />

All works great.
The TreeView is populated and looks fine.

In IE it works all great.

But, in Firefox it does not work.
It just populates the TreeView-Control, but when I want collapse a node, a
javascript error occures.

I dont understand it.
I saw that the javascript-method call on the node is not correctly rendered out.
But I dont know why!!!??

Can anybody help me??

What is the exact Javascript error?

Which js is not rendered? Exactly how does it look?

Did you just change the theme? If so, can you upload your theme to the
Patches section so others can have a look?

What version of IE and FF?

IE is very forgiving, especially for dotnet code and controls. FF is
better at following standards.

In general, if it looks OK in FF then will look OK in IE-- but not the
other way around.

Thanks for your fast answer.
I now that about FF and IE already what you say ;-))

OK, after a long search yesterday I find it out finally.
The Problem was the ClientTarget-Property on the Page-Directive.

When you use a simple TreeView-Control within the Skin-File and call any
Page that use that Theme AND the called Page has the ClientTarget-Property set
within Page-Directive you will receive an Javascript Error.

The Error appears only in my Firefox (3.5.3), when you click on the +/- image to expand or collapse the node.
But the tree is fine populated.

IE works fine.

After I replaced the ClientTarget-Property it works also in my FF Browser.
