To create a report with alternating background color, use the C1.C1Report.Section.OnPrint property of the Detail section to change the C1.C1Report.Section.BackColor property of the section.

To do this, complete the following steps:

1. Open the C1ReportDesigner application. For more information on how to access C1ReportDesigner, see Accessing C1ReportDesigner from Visual Studio.
2. Create a new report|tag=Creating a Basic Report Definition or open an existing report. Once you have the report in the C1ReportDesigner application, you can modify the report properties.
3. Click the Close Print Preview button to begin editing the report.
4. In Design mode, select the report from the drop-down list above the Properties window.
5. Locate the C1.C1Report.C1Report.OnOpen property and enter cnt = 0. This initializes the cnt variable.
6. Next, select Detail from the drop-down list above the Properties window.
7. Locate the C1.C1Report.Section.OnPrint property and click the empty field next to it, and then click the ellipsis button.
8. The VBScrpit Editor appears. Enter the following VBScript expression in the code editor:

cnt = cnt + 1

if cnt mod 2 = 0 then

  detail.backcolor = rgb(200,220,200)

else

  detail.backcolor = rgb(255,255,255)

endif

9. Click the Preview button to preview the report with alternating background.

This topic illustrates the following:

The report will appear with an alternating background color.

Whenever a Detail section is rendered, the counter is incremented and the BackColor property of the Detail section is toggled.
