Hi Marcos ,
Thanks for your update.
Query : In the tutorial has "To perform Syncfusion scaffolding, you should use model and DB context classes in your application." But my DB context as in another project (the data project)
In syncfusion scaffolding we have get grid datasource as from the DB context classes, but we also have the support to bind the remote data to the Grid data source by using the adaptors. Please refer the below link which describes the different types of adaptors used to get the data from server.
Please get back to us if you need further assistance on this.
Regards,
Rajapandiyan S.
