Namespace: DevExpress.XtraRichEdit.API.Native

Assembly: DevExpress.RichEdit.v19.1.Core.dll

Declaration

C#

[ComVisible(true)]
public interface CharacterPropertiesBase

VB.NET

<ComVisible(True)>
Public Interface CharacterPropertiesBase

Related API Members

The following members return CharacterPropertiesBase objects:

• Document.DefaultCharacterProperties
• ListLevel.CharacterProperties

Remarks

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.
