Mail Merging via Document Server
This demo illustrates a scenario, in which mail merge operations are performed dynamically with the help of an external RichEditDocumentServer component.
The RichEditDocumentServer loads a predefined template document containing the static content with embedded mail merge data fields, binds to an external data source and generates the merged document. In this demo, the Bootstrap Rich Text Editor is used to open the resulting merged document for display within a web page.
