When exporting to PDF from Telerik Report Designer the software creates a list of flat links for each TOC entry, but the links are separated in the structure from the TOC Label. While a good start, it would be better to use a main TOC tag under which each line in the TOC would receive a TOCI (Table of Contents Item) tag. Each TOCI would contain the label and link for the respective item. Attaching a few examples to assist.
<TOC> | Table of contents element is an element that contains a structured list of items and labels identifying those items; has its own discrete hierarchy. |
<TOCI> | Table of contents item element is an item contained in a list associated with a table of contents element. |
