Navigation style is the way in which the end user can navigate through the data from the parent set to the child set and vice versa. You can choose the navigation style when you define the CHILD set. There are five possibilities, as described below.
Because you can use different layout styles for different sets in the same export task, you could, for example, use a list layout for the parent set, page jump navigation to the child data in the same file, and table layout for the child data. Once you start to work with the USoft Batch HTML export facility, you will find many ways to work with both the layout and the navigation styles.
One document shows the parent information for each record. A link is added to a separate HTML document containing the child data. For example, the main document might look like this (assuming the default table layout has been used):
where DETAILS is the name of the child set in the export task.
Each of the entries in the DETAILS column links to a separate HTML file, so when you click one, a table such as the following could be displayed.
The parent information and the child data are in the same document. A link is added that points from the parent data to the child data.
In this case, all the data is present on the same page, which is useful if the data is to be printed.
The document shows the parent data with the child data immediately below it.
All the data is contained in one page, so that it can easily be printed, if required.
When frames are used, the parent data is shown in one frame, and the child data in another.
You must specify the frames navigation style for BOTH the parent and child sets, otherwise you will not get the correct results.
If you want to use a tree view, the data you export must consist of parent and child data. For example, if the Travel Agency exports the TOUR and SCHEDTOUR data (with the layout style Table and the navigation style Tree View), the TOUR data will be listed in a tree view in the left frame, and as a table in the right frame.
Clicking an entry in the tree for which there is data results in the child data (from SCHEDTOUR) being displayed in a table the right frame. If there is no data for a particular entry, this is shown in the text in the tree view.
To use the Tree View, you must view the results using Internet Explorer (or another browser that supports ActiveX controls).
