Hi ,

Thanks,

Hi Dayakar,
Thanks for the update.
The frozen rows and columns functionality is not supported with the grouping feature. The EJ2 Grid has limitations for some features as it not compatible with those features. And the frozen Grid functionality is not compatible with the below features,
Documentation: https://ej2.syncfusion.com/angular/documentation/grid/frozen/#limitations-of-frozen-grid
