I am using the following code in the currentpagechanged event to update a spin editor, but the spin editor value does not stay in sync with the Navigator text box when changing pages via the Navigator or clicking on the thumbnails.  

 

private void radPdfViewer1_CurrentPageChanged(object sender, CurrentPageChangedEventArgs e)
        {
            try
            {
                seFrom.Value = int.Parse(this.radPdfViewerNavigator1.CurrentPageTextBox.Text) ;
            }
            catch
            {

            }
        }

Hi Claude,

I have tested this with the following approach for getting the page index and it works on my side: 

private void RadPdfViewer1_CurrentPageChanged(object sender, CurrentPageChangedEventArgs e)
{
    if (e.CurrentPage == null || radPdfViewer1.Document == null)
    {
        return;
    }
    radSpinEditor1.Value = radPdfViewer1.Document.Pages.IndexOf(e.CurrentPage) + 1;
}

Let me know how this works for you.
