some how the tab index is not working for me I tried all methods (selectcell, attachevent, settaborder)but no use.

I want to set other column as readonly but only link columns will get bold on focus…for onmouseover itis working but not for onfocus any idea??

You can use “onTab” event to catch moment of selecting link column while tabbing dhtmlx.com/dhxdocs/doku.php?id=d … vent_ontab
Inside “onTab” event handler you can find out what row and cell is selected with getSelectedRowId() and getSelectedCellIndex() methods
