Is there any way to programmatically manipulate a template document? I would like to try to reduce font to attempt to force/restrict a text to one line.
There is currently no way to modify template documents. You could basically do it using DOM, but our DOM doesn't support ContentControls and custom XML parts, two Word document constructs that are used by Docentric Toolkit. We will add support for these constructs in the future so that it will be possible to manipulate template documents as well (in addition to documents that do not contain these objects).
