Hi Ha Nguyen,
Thanks for using Syncfusion Products.
we have analyzed your query and since the GridControl is a cell based control, we cannot bind the collection to it. Our GridDataControl is a Databound control and we can set collection to it. we have attached a sample as per your requirement. Please find the sample from the attachment.
Please let us know if you have any queries.
Thanks,
Sankar
