What's New

What's New in GcWord

Support for Content Controls

With this service pack, we added the capability of binding content controls to XMP parts using CustomXMLPart class in GcWord.

Add, load, and modify XML parts and save the document with customer XML parts as .docx files.
Edit text in the UI of Word document, and the corresponding XML element will automatically update.  If the element values in the custom XML parts are changed, the bound content controls to the XML elements display the new data.

GcWord adds the GlossaryDocument and BuildingBlock classes. A Glossary document acts as a supplementary document storage. Building blocks are an essential feature of word that allows block to insert blocks of information.
Create, modify and delete building blocks using the BuildingBlock class.
