Some reports have sections that are printed conditionally. For example, if the request form for the report has a Show Address Details check box, then the address details are printed only if the check box is selected. As another example, a report could show data based on a value such as a balance. If the balance is 0, then the report does not show the balance. In the Classic report layout, you can use section triggers to specify the conditions for showing the data. In a client report definition (RDLC) report layout, section triggers are not supported. To specify conditional visibility in an RDLC report layout, use an expression on the Visibility property of the control or table row.
For an example of applying conditional visibility controls to hide nonfiltered headers, see How to: Hide Nonfiltered Headers.
Before you begin this procedure, you must create a layout suggestion for the report. For more information, see How to: Create a Layout Suggestion.
