Thank you. Yes I confirm it is a bug. It is fixed in GitHub - 3.7 version

Best Regards

I am using rownumbers = ture and it works fine when grid displays the first time (or even refreshed) but when I call the "addRowData" to add a new row, it does add the row but fails to add the first column (row number).

I debugged it and found out that the addRowData method passed the incorrect position to "formatCol" method.

So when I changed this line (Version 3.6.5 => grid.base.js => addRowData => Line 1920) from

prp = t.formatCol(ni,1,'');

to

prp = t.formatCol(0,1,'');

Everything worked fine (and the row numbers were added correctly).

It seems like a bug, but let me know if I am missing the plot.

Thanks.

Rahman.
