This example demonstrates how to specify the text markup annotation properties when the annotation is being created in a document.

To add a markup to text:

  • Select the text;
  • Right-click the text and choose Highlight, Strikethrough or Underline item in the invoked context menu.


When the text markup annotation is being created in a document, the PdfViewer.TextMarkupAnnotationCreating event is raised. In this event, you can specify the annotation properties (for example, the default color used to underline a text using the PdfTextMarkupAnnotationCreatingEventArgs.Color property as shown in the code below).

You can see properties applied to a newly created annotation in the Annotation Properties dialog.

To open this dialog, right-click the annotation and choose the Properties… item in the context menu.


The Annotation Properties dialog is shown below.
