Hi, I'm trying to use the RadPageView with Navigation Mode and Hierarchy feature. Is it possible to set all the SubPages to be collapsed (item collapsed, not NavigationView Collapsed) at the Form Load event ?

This is current condition at Form Load (all sub pages are expanded)

 

And this is what I need at Form Load (all the sub pages are collapsed)

 

Thank you.

Hi,

The following code snippet demonstrates how to collapse all items in the navigation view:

            RadPageViewNavigationViewElement navigationElement = this.radPageView1.ViewElement as RadPageViewNavigationViewElement;
            foreach (RadPageViewNavigationViewItem item in navigationElement.Items)
            {
                item.IsExpanded = false;
            }

Design time:

Run time:

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