# Work with Report Parts

This topic describes the End-User Report Designer API that concerns working with the Report Parts.

## Content



[Report parts](/activereportsnet/docs/v20.1/developers/report-parts) are groups of items in a report that you can reuse in other reports. The report parts can be added and managed in the Reports Library.

### Specify a directory for the reports library

With the [Designer.ReportPartsDirectory](/activereportsnet/api/v20.1/MESCIUS.ActiveReports.Design.Win/GrapeCity.ActiveReports.Design.Designer.html) property, you can specify the directory for loading the report items in the report library.

```csharp
_designer.ReportPartsDirectory = "c:\\Data\Reports Library\\";
```
