Modify ImageUrl with Client API

[Skypy]

Hello,

How can I modify ImageUrl with Client API (javascript) ?

Thanks !

I found :

function tabSelecting(sender, eventArgs)
{
    eventArgs.get_tab().set_imageUrl("image.gif")
}

The new ClientSide API is great.

When I set imageUrl with client API, i can see my image and it disappear !

With server API there is no problem, what can I do to make it persist with client API ? and where can I get documentation for the new client API ?

Thanks

I found in CHM (installed with setup) at :
ms-help://MS.VSCC.v80/MS.VSIPCC.v80/telerik.radcontrols.prometheus.2008.Q1/telerik.radcontrols.prometheus.2008.Q1/tab_ClientSideRadTabStrip.html

The code :
tabStrip.trackChanges();
tabStrip.get_tabs().add(tab);
tabStrip.commitChanges();
