Searched forum and couldn't find a related issue. I'm using the PanelBar as Accordion. When a Panel bar item is selected it is displayed, but when the same panel bar item is selected agan it's collapsed. Can this behavior be prevented

If a panelbar item is already selected it stay selected and do not collapses. That means I want "ALWAYS" a panel bar item to be visible.

I'd rather prefer a XAML only solution.

Regards

Hello Frederic,

I will post the answer from your support ticket also here in the forum.

"To achieve your requirement you can subscribe for the PreviewCollapsed event of the RadPanelBar control and handle it when all items are collapsing. Here is an example in code for this approach:

private void RadPanelBar_PreviewCollapsed(object sender, Telerik.Windows.RadRoutedEventArgs e)
{
    var panelBar = (RadPanelBar)sender;
    var areAllItemsCollapsing = panelBar.Items.OfType<RadPanelBarItem>().All(x => !x.IsExpanded);        
    e.Handled = areAllItemsCollapsing;
}
"

I am afraid that, I can't suggest you a XAML-only approach.

Regards,
Martin
