Working with Tags

Get Note Tag Details from a OneNote Document

The NoteTag class provides all the properties related to a note tag in a Microsoft OneNote document. All the OneNote file’s note tags are contained by RichText nodes of the Document object. The code example given below demonstrates how to get details about each note tag from a OneNote document.

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

// Load the document into Aspose.Note.
Document oneFile = new Document(dataDir + "TagFile.one");

// Get all RichText nodes
IList<RichText> nodes = oneFile.GetChildNodes<RichText>();

// Iterate through each node
foreach (RichText richText in nodes)
{
    foreach (var tag in richText.Tags)
    {
        if (tag is NoteTag)
        {
            NoteTag noteTag = (NoteTag)tag;
            // Retrieve properties
            Console.WriteLine("Completed Time: " + noteTag.CompletedTime);
            Console.WriteLine("Create Time: " + noteTag.CreationTime);
            Console.WriteLine("Font Color: " + noteTag.FontColor);
            Console.WriteLine("Status: " + noteTag.Status);
            Console.WriteLine("Label: " + noteTag.Label);
            Console.WriteLine("Icon: " + noteTag.Icon);
            Console.WriteLine("High Light: " + noteTag.Highlight);
        }
    }
}

Tag Important Notes in the OneNote Document

The NoteTag class provides all the properties related to a note tag. Users can now tag text, image and tables. Aspose.Note for .NET APIs supports all these feature operations.

Add a New Text Node with a Tag

The code example given below demonstrates how to add a new text node with a tag in the OneNote document.

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

// Create an object of the Document class
Document doc = new Document();
// Initialize Page class object
Aspose.Note.Page page = new Aspose.Note.Page(doc);
// Initialize Outline class object
Outline outline = new Outline(doc);
// Initialize OutlineElement class object
OutlineElement outlineElem = new OutlineElement(doc);
ParagraphStyle textStyle = new ParagraphStyle { FontColor = Color.Black, FontName = "Arial", FontSize = 10 };
RichText text = new RichText(doc) { Text = "OneNote text.", ParagraphStyle = textStyle };
text.Tags.Add(new NoteTag
{
    Icon = TagIcon.YellowStar,
});

// Add text node
outlineElem.AppendChildLast(text);
// Add outline element node
outline.AppendChildLast(outlineElem);
// Add outline node
page.AppendChildLast(outline);
// Add page node
doc.AppendChildLast(page);

dataDir = dataDir + "AddTextNodeWithTag_out.one";
// Save OneNote document
doc.Save(dataDir);

Add a New Image Node with a Tag

The code example given below demonstrates how to add a new Image node with a tag in the OneNote document.

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

// Create an object of the Document class
Document doc = new Document();
// Initialize Page class object
Aspose.Note.Page page = new Aspose.Note.Page(doc);
// Initialize Outline class object
Outline outline = new Outline(doc);
// Initialize OutlineElement class object
OutlineElement outlineElem = new OutlineElement(doc);
// Load an image
Aspose.Note.Image image = new Aspose.Note.Image(doc, dataDir + "icon.jpg");
// Insert image in the document node
outlineElem.AppendChildLast(image);
image.Tags.Add(new NoteTag
{
    Icon = TagIcon.YellowStar,
});
// Add outline element node
outline.AppendChildLast(outlineElem);
// Add outline node
page.AppendChildLast(outline);
// Add page node
doc.AppendChildLast(page);

dataDir = dataDir + "AddImageNodeWithTag_out.one";
// Save OneNote document
doc.Save(dataDir);

Add a New Table Node with a Tag

The code example given below demonstrates how to add a new Table node with a tag in the OneNote document.

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

// Create an object of the Document class
Document doc = new Document();
// Initialize Page class object
Aspose.Note.Page page = new Aspose.Note.Page(doc);
// Initialize TableRow class object
TableRow row = new TableRow(doc);
// Initialize TableCell class object
TableCell cell = new TableCell(doc);
// Insert cell content
cell.AppendChildLast(InsertTable.GetOutlineElementWithText(doc, "Single cell."));
// Add cell to row node
row.AppendChildLast(cell);
// Initialize table node
Table table = new Table(doc)
{
    IsBordersVisible = true,
    Columns = { new TableColumn { Width = 70 } }
};
// Insert row node in table
table.AppendChildLast(row);
// Add tag to this table node
table.Tags.Add(new NoteTag
{
    Icon = TagIcon.QuestionMark
});

Outline outline = new Outline(doc);
OutlineElement outlineElem = new OutlineElement(doc);
// Add table node
outlineElem.AppendChildLast(table);
// Add outline elements
outline.AppendChildLast(outlineElem);
page.AppendChildLast(outline);
doc.AppendChildLast(page);

dataDir = dataDir + "AddTableNodeWithTag_out.one";
// Save OneNote document
doc.Save(dataDir);
