    I want to find a way to programatically detect if a PageViewPage has just loaded so that I could bind the controls that are on that page?
    Method SelectedPageChanged works great when you click on the handle of a Page, but it is not what I am needing.

    Just so you understand my situation; I have a top level RadPageView with many PageViewPages (Section A, Section B, Section C, Section D, Section E...etc...etc). Inside each one of the PageViewPages, I have another RadPageView control with many PageViewPages of its own (Section E - Page 1, Section E - Page 2). Please see attached screenshot for details.

    For instance, when I click on one of the PageViewPages (Section E) of the top level RadPageView; I want to detect which PageViewPage of the lower level RadPageView control is visible and active, so that I can popluate all controls on that PageViewPage only, with values from the database.
    How can this be accomplished?

    Hi Adrian,

    Thank you for contacting us.

    I tested your case using a RadPageView with two Pages. Each of the Pages contain one RadPageView instance with another two Pages. Each of the inner Pages contains two controls: either RadButtons or RadCheckBoxes.

    The following code snippet illustrates how to reach the controls in the active Page of the nested RadPageViews, i.e. the RadButtons and the RadCheckBoxes:

    public Form1()
    {
        InitializeComponent();
        new RadControlSpyForm().Show();
        this.radPageView1.SelectedPageChanged += new EventHandler(radPageView1_SelectedPageChanged);
        this.radPageView2.SelectedPageChanged += new EventHandler(radPageView1_SelectedPageChanged);
        this.radPageView3.SelectedPageChanged += new EventHandler(radPageView1_SelectedPageChanged);
    }
     
    private void radPageView1_SelectedPageChanged(object sender, EventArgs e)
    {
        RadPageViewPage selectedPage = radPageView1.SelectedPage;
     
        foreach (Control control in selectedPage.Controls)
        {
            RadPageView nestedPageView = control as RadPageView;
            if (nestedPageView != null)
            {
                RadPageViewPage selectedNestedPage = nestedPageView.SelectedPage;
                foreach (Control nestedControl in selectedNestedPage.Controls)
                {
                    SetControlsText(nestedControl);
                }
            }
        }
    }
     
    private void SetControlsText(Control control)
    {
        //implement your own logic here
        control.Text = "This Page is Active";
    }

    I hope you find this useful. Let me know whether the above suggestion helps.

    Kind regards,
