Question

CSS wont work on a treeview control after disabling "EnableCliendScript" option

Asked by: urir10

Hi All
I have a treeview control that shows the sites menu. I have added a css file that gave it a hover effect for each node. Then i had to disable the  "EnableCliendScript" property because it was messing up the collapse/Expand feature of the treeview (When combined with the ajax updatepanel). After disabling that property i dont get the hover effect anymore, everything else works fine but not the hover effect.

What can i do to fix it?

Yes sorry forgot to do it in the first place. Here is what ive got:


This is the effect i want when the nodes are hovered over works fine when i turn the  "EnableCliendScript" property to True, but then the collapse/expand does not work properly because its inside the update panel. When the  "EnableCliendScript" property is false everything else works but not the hover over effect.

My server is having some problems so asp* is a bit hard to test.

I assume you validates the CSS?

Olny reason I mention that is there is an error on the HOVER.

line 32 .HomeNode:hover Value

Error : text-indent only 0 can be a length.

You must put a unit after your number : 20  

I'll try to get back soon.

I have to deal woth some trouble I just Discovered..
