Hiding Report Sections
Crystal Reports has three properties you can set to hide report sections.
- Hide (Drill-Down OK)
- Suppress (No Drill-Down)
- Suppress Blank Section
To hide a section
The Hide property hides a section whenever you run the report. For example, in a summary report, the Hide property can be used to display only the summaries, but not the details behind the summaries. When the Hide property is applied to a section, it becomes visible when the Drill-down cursor is used to drill down on the section contents. This property is absolute; it cannot be conditionally applied using a formula.
- Right-click the report section and select Hide (Drill-Down OK).
To suppress a section
The Suppress property also hides a section when you run the report. Unlike the Hide property, however, you cannot apply the Suppress property, then drill down to reveal the section contents. This property can be applied absolutely, or conditionally using a formula. This is useful for writing form letters. For example, in a form letter, you might create two Details sections: one to suppress when sales are over $X and one to suppress when sales are under $X.
- Right-click the report section and select Suppress (No Drill-Down).
To suppress a blank section
The Suppress Blank Section property hides a section whenever there is nothing in it. If something is placed within the section, then it becomes visible.
- Right-click the report section and select Format Section. In the Section Expert, click the Suppress Blank Section check box.
