The C1ReportViewer supports parameters for C1Report and C1RdlReport reports. A Parameters pane will be shown above the control when a report requires input parameters. The Parameters pane can be collapsed or expanded during report viewing. Parameters must be filled in by the user before report generation starts.

The list of properties used in the sample:

• FileName - a relative path to the file with report. In this sample, value for this property is set to "~/C1ReportViewer/RDL/ReportParameters01.rdl".
• Zoom - a page zoom value. Accepts named zoom values like "actual size", "fit page", "fit width", "fit height", or value in percentages, e.g. "50%", "70%". For this sample, we are using "75%".
• Height - a height of the control. For this sample, we are using "475px".
• Width - a width of the control. For this sample, we are using "100%".
