Report Book Parameters

Report Book Parameters

Often one or more reports that are part of a report book will contain report parameters. The report book is shown as a single document in the report viewer and the parameters area is constructed based on the report parameters defined in all child reports.

Telerik Reporting provides a mechanism known as parameter merging. The rule for merging parameters is straightforward. If the Name and Type of two (or more) parameters from different reports are the same, then they are considered equivalent and are displayed as a single parameter in the parameters area.

Note Note
When one or more parameters are merged the UI settings of the first one are used for displaying it in the parameters area.

You can control parameter merging via the Mergeable boolean property of the ReportParameter class. The default value of the Mergeable property is true. Set the Mergeable property to false if you want to prevent a parameter from being merged with its equivalent ones.
