Hi Richard,
Thank you for your interest in Syncfusion Products.

You can use the 'Grid Grouping Control' instead of the DataBoundGridControl.
The Grid Grouping Control supports some additional functionalities like Grouping, Summaries…
The online demo for the 'Grid Grouping Control' can be obtained from the following location,
