Windows Forms). They are currently working on new features for version 16.0. Today, I would like to announce two improvements: - **Master-Detail: Nested Merge Blocks** - **Image Merge Fields** A master-detail relationship is a 1:n (one-to-many) type relationship. A typical example for such a relationship is a purchase order and a set of items that belongs to each purchase order. This new feature allows you to create complex nested reports in a very easy way. The following screenshot shows such a nested block: [![Master-Detail Sample Document](https://s1-www.textcontrol.com/assets/dist/blog/2010/08/31/a/assets/nested_blocks_zoom.webp "Master-Detail Sample Document")](https://s1-www.textcontrol.com/assets/dist/blog/2010/08/31/a/assets/nested_blocks_zoom.webp) Image merge fields is another oft-requested feature. These image merge fields are normal merge fields with a special indicator. Such fields can be replaced with images during the merge process. This enables you to create templates with placeholders for company logos or signature images. As soon as I get a pre-build version, I will publish a sample application with these great new features on TX Text Control Labs. --- ## About Bjoern Meyer As CEO, Bjoern is the visionary behind our strategic direction and business development, bridging the gap between our customers and engineering teams.
