Hi Rekha,
Attached is the sample which illustrates the toggling datasource dynamically for GridGroupingControl based on user selection.
TogglingDatasource.zipIn our sample, we bind the grid based on user selection from the DropDownlistBox. We acheived this with the help of callback panel.
Let us know if need more help.
Thanks for using Syncfusion products.
