Hi Saravanan,
Thank you for contacting Syncfusion support.
We have checked your reported query in that you are trying to dynamically set the data to the spreadsheet by using datasource property. We suspect that you are tried to set the data like two way binding (changing the 'data' property in AppComponent class need to updated in Spreadsheet). We would inform you that currently, we does not have this support on our spreadsheet. We have considered this as improvement in our end and this support will be included in any of our upcoming release. However, we have provided the workaround for your reported scenario, in that we have rendered the spreadsheet when data loaded by setting the ngIf as true. In this way, you can achieve your requirement. Please refer the below sample link.
