Use Case

Let’s say that we want to show the movies catalog that lists movies along with the movie information - release year, user rating and movie length, with the Table of Contents at the beginning of the report to be able to navigate to the specific genre or movie of choice.

Let us first create a report for which we will add Table of Contents later. The report uses two List data regions with few TextBox controls to show [YearReleased], [MPAA], [UserRating] and [Length] of the movie. The report uses the Group Expressions on List data regions to group movies by genre and title. The report layout will be as shown:

Design-time	Preview

1. Create an RDL Report and drag-drop the List data region (List1) on the report’s designer.
2. Set the Group Expression property to =Fields!GenreName.Value.
3. Drag-drop the TextBox control onto the List data region and bind it to [GenreName]. This will be the header of the catalog section.
4. Drag-drop another List data region (List2) onto the first List.
5. Set the Group Expression property to =Fields!Title.Value.
6. Drag-drop the TextBox control onto the List data region and bind it to [Title]. This will be the header of each catalog entry for a movie.
7. Next, drag-drop few TextBox controls below the [Title] on List2, and set their Value property as follows:
   • TextBox3: ="Released in: " & Fields!YearReleased.Value & ", " & Fields!Country.Value
   • TextBox4: ="The MPAA Rated this Film: " & Fields!MPAA.Value
   • TextBox5: User Rating:
   • TextBox6: =Fields!UserRating.Value
   • TextBox7: ="Length: " & Fields!Length.Value & " min"
8. To add the report title, drag-drop the TextBox control on top of the report and set its Value to "Movies Catalog".
9. Improve the appearance of report by adjusting the properties of the report controls used.
10. Preview.

Now lets add Table of Contents control to show the report or document map.

To add items to Table of Contents using Heading Level Property

You can define a hierarchical structure for your report using the Heading Level property of the TextBox control. If a TextBox is set to Heading Level 1 and another TextBox displaying a group header to Heading Level 2, the entries in Heading Level 2 are clubbed under the Heading Level 1 entry in the Table of Contents. The headings are auto-numbered.

1. Drag-drop the Table of Contents control on top of the report, below report title. Grab its corner and adjust its size.

2. Select the Level1 (to display GenreName) in the Table of Contents and set the following properties:

   • Text > Color: #0096aa
   • Font Size: 14pt
   • Fill Character: "-" (a dash)
   • Display Fill Character: True

3. Click +Add item to add the Level2 (to display Title) to the Table of Contents and set the following properties:

   • Font Size: 10pt
   • Padding: 5 pt (on left)
   • Fill Character: "." (a dot)
   • Display Fill Character: True

   

4. From the Report Explorer, select Report and set its Document Map properties as follows.

   

   • Levels : Set the styles from the drop-down.
     • Level.0: A,B,C,D,E
     • Level.1: 1,2,3,4,5
   • Source: Headings

5. Select Textbox with value [GenreName] and set Heading Level property to 1.

To add items to Table of Contents using Label Property

By setting the Label property of the controls in your report, you can show a hierarchical structure based on the parent - child relationship between the controls in the Document Map. For example, if the Label property of the List data region is set and a TextBox control is place inside the List data region, the TextBox label appears nested inside the List data region label, thereby displaying a hierarchical structure.

1. Drag-drop the Table of Contents control on top of the report. Grab its corner and adjust its size.

2. Follow steps 2 and 3 of "To add items to Table of Contents using Heading Level Property" section for setting properties of levels in Table of Contents.

3. From the Report Explorer, select Report, and set Document Map > Source property to 'Labels'.

   

4. Select the List1 data region and set its Label property to =Fields!GenreName.Value to have it displayed in the Level1 of the Table of Contents.

   

   Note: The Table of Contents mapped using labels are not numbered. In this case, if you want to add numbering in Table of Contents, you need to use DocumentMap.Path expression in the Label property of the List data region. For example, to add numbering on the first level (GenreName), select List1 data region and set Label property to: =DocumentMap.Path & ". " & Fields!GenreName.Value.

5. Similarly, select the List2 data region and set its Label property to =Fields!Title.Value to have it displayed in the Level2 of the Table of Contents.
