CHAPTER 15 Working with TreeViews
Users Guide 461
What you can do
All of the techniques available in a tabular report, such as moving controls and
specifying display formats, are available for modifying and enhancing
TreeView reports. See “Adding and deleting TreeView levels” next to read
more about the bands in a TreeView report and see how to add features
especially suited for TreeView reports, such as additional TreeView levels or
summary statistics.
Report is not updatable by default
When you generate a report using the TreeView presentation style, InfoMaker
makes it not updatable by default. If you want to be able to update the database
through the TreeView report, you must modify its update characteristics. For
more information, see Chapter 19, “Controlling Updates in Forms.”
Adding and deleting TreeView levels
You add and delete TreeView levels using the Rows menu in the Report
painter.
❖ To create an additional level in a TreeView report:
1 Open the TreeView report if it is not already open.
2 Select Rows>Create TreeView Level from the menu bar.
The Specify Group Columns dialog box displays.
3 Specify the columns you want to set as the next TreeView level by
dragging them from the Source Data pane to the Columns pane.
In the sample report shown in “Example” on page 456, the second level
has a single column, the
employee_city column.
