Hello,

i think that is a good Idea to change this Properties.


Here is my Scenario...
To determine the start of a report in a ReportBook, i use the following code:

ReportBook m_Book = new ReportBook();

m_Book.Reports.Add(m_Report1);
m_Book.Reports.Add(m_Report2);

m_Book.DocumentName = "Sample Report";

InstanceReportSource m_Source = new InstanceReportSource();

m_Source.ReportDocument = m_Book;

m_Window = new ReportPreview();
m_Window.ReportViewer.ReportSource = m_Source;

m_Window.ReportViewer.RenderingEnd += ReportViewer_RenderingEnd;

m_Window.WindowState = WindowState.Maximized;
m_Window.ShowDialog();
			
private void ReportViewer_RenderingEnd(object sender, EventArgs e)
        {
			// Get the ControlTemplate from ReportViewer Control
            var template = m_Window.ReportViewer.Template;
			
			// Get the RadTreeView from DocumentMapTreeView
            var myControl = (RadTreeView)template.FindName("DocumentMapTreeView", m_Window.ReportViewer);

			// Clear the Collection
            m_DocumentMapList.Clear();

            foreach (DocumentMapNodeModel m_Item in myControl.ItemsSource)
            {
				// Get the Item and add to local Collection
                m_DocumentMapList.Add(m_Item);
            }
		
			m_Window.ReportViewer.RenderingEnd -= ReportViewer_RenderingEnd;
			
			// here i make the Table of Contents...
			
			TableOfContents.Add(new CustomObject("I.", "First Chapter", m_DocumentMapList.Where(x => x.Label == "DocumentMapText").FirstOrDefault().Page));
			
			TableOfContents.Add(new CustomObject("II.", "Second Chapter", m_DocumentMapList.Where(x => x.Label == "AnotherDocumentMapText").FirstOrDefault().Page));
			
			// Refresh the Reports
			m_Window.ReportViewer.RefreshReport();
			}

it works, but this way is somewhat inconvenient

My example is only a small excerpt from the complete code
