Referencing Assemblies in an RDL File
To support the use of custom code assemblies in report definition files, two Report Definition Language (RDL) elements are included in the RDL specification: the CodeModules element and the Classes element.
The CodeModules element enables you to refer to managed code assemblies in report expressions. CodeModules is a top-level element that contains the reference to the assembly that you use in your report definition files to call specialized functions. An entry in a report definition that supports the use of a custom assembly might look like the following:
<CodeModules> <CodeModule>CurrencyConversion, Version=1.0.1363.31103, Culture=neutral, PublicKeyToken=null</CodeModule> </CodeModules>
You can manually add CodeModule elements to your RDL file or you can use the Code tab of the Report Properties dialog to add references to assemblies in your report. For more information, see Writing Custom Code.
The Classes element supports the use of instance members in a report definition. Classes is a top-level element that contains a reference to the class name and an instance name. An entry in a report definition that supports the use of instance members might look like the following:
<Classes> <Class> <ClassName>CurrencyConversion.DollarCurrencyConversion</ClassName> <InstanceName>m_myDollarConversion</InstanceName> </Class> </Classes>
