Hi Chin,
Thanks for your interest in Syncfusion Products.
The layout provided in update that you would like to have in grid can be achieved in GridGroupingControl by means of the StackedHeaders functionality. Please refer to the following User Guide documentation link where this functionality has been illustrated.
http://help.syncfusion.com/ug_74/gridwin/StackedMultiheaders.htmlWith respect to GridDataBoundGrid, you would have to manually handle some code to achieve the similar layout. Please post your further queries related to GridDataBoundGrid by opening a DT support incident where this can be discussed briefly.
Regards,
Rajadurai
