PanelBar Collapse

[Shmulik]

When navigating to a page that is not one of the panel items the panel collapses, is there a way to make it return to load status?

Hello Shmulik,

You can set the PersistStateInCookie property to true.

Please see also our online examples:

Hi Rosi,
Thanks for your reply, it was very helpful.
is there a way we can make the panel expand to all the parent (only top level).
same as it starts when you first load the page?
Thanks

Hello Shmulik,

Yes, you can do this by javascript collapsing all items and expanding these from first level:

<script>
function pageLoad()
{

    var panel = $find("RadPanelBar1");
    var items =panel.get_expandedItems();
    for(var i = 0;i<items.length;i++)
    {
           items[i].collapse();
    }
    for(var i = 0;i<panel.get_items().get_count();i++)
    {
           items[i].expand();
    }

}
</script>

or you can do this on server side by hooking on the PreRender event of RadPanelBar:

protected void RadPanelBar1_PreRender(object sender, EventArgs e)
{
            RadPanelBar1.CollapseAllItems();
            for (int i = 0; i < RadPanelBar1.Items.Count; i++)
            {
                RadPanelBar1.Items[i].Expanded = true;
            }
}
