[Neelamegan]

While loading the form by default collapse all the page(pages and sub pages) and expand only default page.

Hi, Neelamegan,

The Following code snippet demonstrates how to collapse the pages:

            foreach (RadPageViewNavigationViewItem item in this.radNavigationView1.NavigationViewElement.Items)
            {
                item.IsExpanded = false;
            }

If you want to leave at least one RadPageViewNavigationViewItem expanded, do not set its IsExpanded property to false.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
