Hi Rasika,
Thank you for your interest in Syncfusion products.
In our Grid Grouping Control, we have a method GetSelectedRanges().From this you can get the details of rows and columns. Please refer the below code snippet for further clarification.
Code snippet:
GridRangeInfoList range; int startindex, endindex;
this.ggcGrid.TableModel.Selections.GetSelectedRanges(out range, true);
startindex = range.ActiveRange.Top;
endindex = range.ActiveRange.Bottom;
Please let us know if you have any concerns.
Thanks & Regards,
AL.Solai
