Public Interface CharacterPropertiesBase
The following members return CharacterPropertiesBase objects:
The CharacterPropertiesBase interface allows you to get/set character formatting.
Use the SubDocument.BeginUpdateCharacters and the SubDocument.EndUpdateCharacters paired methods to modify character formatting, such as the CharacterPropertiesBase.FontName, CharacterPropertiesBase.FontSize, CharacterPropertiesBase.Bold, CharacterPropertiesBase.ForeColor etc.
To accomplish this, call the SubDocument.BeginUpdateCharacters method for the specified range, use the returned CharacterProperties interface to modify the required properties and call the SubDocument.EndUpdateCharacters method to finalize the modification.
Note
Make sure that the SubDocument.BeginUpdateCharacters method always has its corresponding SubDocument.EndUpdateCharacters method to ensure proper operation of the control.
The following code snippet changes the font and the color of the selected text.
document.BeginUpdate();
document.AppendText("Normal\nFormatted\nNormal");
document.EndUpdate();
// The target range is the second paragraph
DocumentRange range = document.Paragraphs[1].Range;
// Create and customize an object
// that sets character formatting for the selected range
CharacterProperties cp = document.BeginUpdateCharacters(range);
cp.FontName = "Comic Sans MS";
cp.FontSize = 18;
cp.ForeColor = Color.Blue;
cp.BackColor = Color.Snow;
cp.Underline = UnderlineType.DoubleWave;
cp.UnderlineColor = Color.Red;
// Finalize modifications
// with this method call
document.EndUpdateCharacters(cp);
document.BeginUpdate()
document.AppendText("Normal" & vbLf & "Formatted" & vbLf & "Normal")
document.EndUpdate()
' The target range is the second paragraph
Dim range As DocumentRange = document.Paragraphs(1).Range
' Create and customize an object
' that sets character formatting for the selected range
Dim cp As CharacterProperties = document.BeginUpdateCharacters(range)
cp.FontName = "Comic Sans MS"
cp.FontSize = 18
cp.ForeColor = Color.Blue
cp.BackColor = Color.Snow
cp.Underline = UnderlineType.DoubleWave
cp.UnderlineColor = Color.Red
' Finalize modifications

document.EndUpdateCharacters(cp)
