Hi Natarajan,
Thank you for your interest in syncfusion products,
The GridGroupingControl has to get focused on the cell which has animated spinner with a specific time interval.
So the cell of the GridGroupingControl must be redrawn at specific time interval, this can be done using InvalidateRange() method which should be done in the Timer event where the range should be specified for the animated cell.
Please refer the below code snippet for mor details:
this.gridGroupingControl1.TableControl.InvalidateRange(GridRangeInfo.Cell(rowindex, colindex));
Let me know if you have any queries.
Regards,
Ragamathullah B.
