Thanks Alex, what we had in mind was the "mouse click" instead of the "mouse wheel",  however, your approach solves our problem.

Regards,

Well, yes.

I am not sure this is something we can go around easily. It would ask you to choose where you want to go. If you have two layouts as children, you would have to choose one as it would not go directly. However, if you have only one, the "transition" is automatic.

Thank you for your kindly help. It is working now

I tried this command "xamDataCarousel1.ActiveRecord.IsExpanded=false" but it had not been worked. But now I know why it did not work. Becouse I worked on standart datacarousel example and when I sent that command to datacarousel, on datacarousel a context menu seemed  and in menu two hierarchical option and it asked me to which option do you prefer.

Thanks.

Hello,

I suppose by Mouse Navigation you have in mind mouse wheel. If so, you can handle the PreviewMouseWheel event and expand the ActiveRecord.

 void xamDataCarousel1_PreviewMouseWheel(object sender, MouseWheelEventArgs e)

        {

            if (xamDataCarousel1.ActiveRecord != null)

                xamDataCarousel1.ActiveRecord.IsExpanded = true;

        } 

This is for going down in the hierarchy. Regarding the way up, it is really up to you to implement that.

Basically you would have to make difference between when the user wants to go up or just navigate the records. Here is what I have done.

1. The user selects record and scrolls -> goes down the hierarchy.

2. The user selects again record and scrolls:

      2.1 If scrolling is down -> record expands, goes down the hierarchy again.

      2.2 If scrolling is up -> record collapses, goes up the hierarchy.

void xamDataCarousel1_PreviewMouseWheel(object sender, MouseWheelEventArgs e)

        {

            if (e.Delta < 0 && xamDataCarousel1.ActiveRecord!=null && xamDataCarousel1.ActiveRecord.ParentDataRecord!=null)

            {

                FieldLayout fieldLayout = xamDataCarousel1.ActiveRecord.FieldLayout;

               xamDataCarousel1.ActiveRecord.ParentDataRecord.IsExpanded = false;

               xamDataCarousel1.ActiveRecord = null;

            }

            if ( xamDataCarousel1.ActiveRecord != null)

            {

                xamDataCarousel1.ActiveRecord.IsExpanded = true;

                xamDataCarousel1.ActiveRecord = null;

            }

        }

Hope this is what you were looking for and helps
