Resource assignments define relationship between tasks and resources.

Use the dataSource option to bind the widget to a data source, which contains resource assignments. If the field names in your data source differ from the 'id', 'resourceId' and 'taskId' default names, use the keyExpr, resourceIdExpr and/or taskIdExpr options to map data fields.
