Conditionally Suppress Controls

This document describes how to display or hide a report control in a published document based on a specified logical condition.

Warning

Use the approach below if expression bindings are not enabled in the Report Designer (the Property Grid does not provide the Expressions tab ).

See Conditionally Suppress Controls if expression bindings are enabled in the Report Designer (the Property Grid provides the Expressions tab).

1. Create a new report or open an existing one and prepare the report layout.

2. Select the required control and click its smart tag. In the invoked actions list, click the Formatting Rules property's ellipsis button.

   

3. In the invoked Formatting Rules Editor, click the Edit Rule Sheet button.

   

4. In the invoked Formatting Rule Sheet Editor, click the plus button to create a new formatting rule. Set the Visible property to False and click the Condition property's ellipsis button.

   

5. In the invoked Condition Editor, specify the required visibility condition.

   

   Click OK to save the changes and close the dialog. Then, click Close to quit the Formatting Rule Sheet Editor.

6. In the Formatting Rules Editor, you can see the created rule (called formattingRule1), which should be moved to the list of active rules on the right using the arrow buttons in the center of the dialog box.

   

   In this editor, you can also customize the precedence of formatting rules using the up and down arrow buttons on the right of the dialog box. The rules are applied in the same order that they appear in the list, and the last rule in the list has the highest priority.

When switching to Print Preview, you can view the report control's visibility changes according to the assigned condition.
