Examples

Shows how to restore previous version of a page.

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_Pages();

// Load OneNote document and get first child           
Document document = new Document(dataDir + "Aspose.one");
Page page = document.FirstChild;           
Page previousPageVersion = document.GetPageHistory(page).Last();

document.RemoveChild(page);
document.AppendChildLast(previousPageVersion);

document.Save(dataDir + "RollBackRevisions_out.one");

Shows how to edit page’s history.

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_Pages();

// Load OneNote document and get first child           
Document document = new Document(dataDir + "Aspose.one");
Page page = document.FirstChild;

var pageHistory = document.GetPageHistory(page);

pageHistory.RemoveRange(0, 1);

pageHistory[0] = new Page(document);
if (pageHistory.Count > 1)
{
    pageHistory[1].Title.TitleText.Text = "New Title";

    pageHistory.Add(new Page(document));

    pageHistory.Insert(1, new Page(document));

    document.Save(dataDir + "ModifyPageHistory_out.one");
}

Shows how to check if a page is a conflict page(i.e. it has changes that OneNote couldn’t automatically merge).

string dataDir = RunExamples.GetDataDir_Pages();

// Load OneNote document
Document doc = new Document(dataDir + "Aspose.one", new LoadOptions { LoadHistory = true });

var history = doc.GetPageHistory(doc.FirstChild);
for (int i = 0; i < history.Count; i++)
{
    var historyPage = history[i];
    Console.Write("    {0}. Author: {1}, {2:dd.MM.yyyy hh.mm.ss}",
                    i,
                    historyPage.PageContentRevisionSummary.AuthorMostRecent,
                    historyPage.PageContentRevisionSummary.LastModifiedTime);
    Console.WriteLine(historyPage.IsConflictPage ? ", IsConflict: true" : string.Empty);

    // By default conflict pages are just skipped on saving.
    // If mark it as non-conflict then it will be saved as usual one in the history.
    if (historyPage.IsConflictPage)
        historyPage.IsConflictPage = false;
}

doc.Save(dataDir + "ConflictPageManipulation_out.one", SaveFormat.One);
