To specify whether Page Header and Page Footer sections should appear on all pages, or be suppressed on the pages that contain the report Header and report Footer sections use C1Reports PageHeader and PageFooter properties.

Sometimes you may want to further customize this behavior. For example, you may want to render different headers on odd and even pages. This can be done with some script that shows or hides fields depending on the page being rendered. To do this, complete the following steps:

1. Open the C1ReportDesigner. For more information on how to access the C1ReportDesigner, see Accessing C1ReportDesigner from Visual Studio.
2. Create a new report or open an existing report. Once you have the report in the C1ReportDesigner, you can modify the report properties.
3. Click the Close Print Preview button to begin editing the report.
4. In Design mode, select Detail from the drop-down list above the Properties window.
5. Locate the OnFormat property and click the empty field next to it, and then click the ellipsis button.
6. The VBScript Editor appears. Enter the following VBScript expression in the code editor:

   odd = (page mod 2 <> 0)
   h1odd.Visible = odd
   h2odd.Visible = odd
   h1even.Visible = not odd
   h2even.Visible = not odd
   

   This script will show or hide fields for odd and even pages if a report header contains several fields named "h<x>odd" and "h<x>even".

   Note that to prevent the page header from showing blank spaces, all the fields should have the CanShrink property set to True.
