Question

Topic is self explanatory.

I found xaml code to do it for an Expander, I found default styles on the DevExpress website so you can change it, but nowhere do I find the right RoutedEvent or property to simply change the animation speed so it instantly collapses/expands.

I think it should be something like the code below, as I found for an Expander style. But I don’t know the RoutedEvent that’s needed.

Seems to be the event, but it doesn’t work if I use it in my xaml.

Any help would be much appreciated!

<dxnav:NavBarControl.Triggers>
    <EventTrigger RoutedEvent="GroupExpanded">
        <EventTrigger.Actions>
            <BeginStoryboard>
                <Storyboard>
                    <DoubleAnimation From="0" To="1" Duration="0:0:0.0" Storyboard.TargetName="navBarControl1" Storyboard.TargetProperty="(FrameworkElement.LayoutTransform).(ScaleTransform.ScaleY)"/>
                </Storyboard>
            </BeginStoryboard>
        </EventTrigger.Actions>
    </EventTrigger>
</dxnav:NavBarControl.Triggers>

Maybe you simply want to change the default animation. Check the answer to this question: NavBarGroup speed
