Hi Doan,
Thanks for contacting Syncfusion support.
Query: when using frozen columns with row spanning in grid the data not showIn attack file, I have list 26 data but it do not show in grid.
We checked the attached screenshot and found that you have used the row spanning with frozen columns in your grid application. By default in EJ2 Grid we do not have support for row spanning with frozen feature, so the data is not displayed in the Grid.
Please get back to us if you need further assistance.
Regards,
Ajith G.
