# Data Mappings

Easily integrate completely customized Microsoft Office style scheduling functionality to build intuitive, polished-looking scheduling applications using Scheduler for WinForms.

## Content

The easiest way to set mappings is to use the **Data Source settings** dialog box in the **C1Schedule Smart Designer**. For more information on accessing the **C1Schedule Smart Designer**, see [C1Schedule Smart Designer](/componentone/docs/win/online-schedule/concepts/scheduer-views/designtimesupport/schedulerforwinforms5/c1schedulesmartdesig).

From this dialog box, you can set **DataSource** and **DataMember** properties for all **Scheduler for WinForms** storages. After setting the data source and data member, set the required and optional fields for the storage mapping.

All objects in the **Scheduler for WinForms**' object model are identified by either **Id** or **Index** property. To allow data to be correctly restored from your data sources you should specify mapping either for the [IdMapping](/componentone/docs/win/online-schedule/) or [IndexMapping](/componentone/docs/win/online-schedule/) properties, which makes sense if you bind to your data storages of Resources, Labels, Contacts or Categories. [C1Schedule](/componentone/docs/win/online-schedule/) saves only Ids or Indexes of these objects in the AppointmentStorage. If there is no mapping for IdMapping or IndexMapping, C1Schedule will not be able to identify the appointment's properties correctly in storages initialized by your data.

To map a data table to the C1Schedule control, first set either the **Id mapping** drop-down list to a Globally Unique Identifier (GUID) field or the **Index mapping** drop-down list to an Integer field.
