I have a related problem.

In my second grid I have currently the following

WITH thisform.grdOperators 
     .colEmail.DynamicCurrentControl = "iif(not EMPTY(csrOperators.Email),'chkEn','chkDis')"   
     .colNetSend.DynamicCurrentControl = "iif(not EMPTY(csrOperators.NetSend),'chkEn','chkDis')"   
     
     .colPager.DynamicCurrentControl = "iif(.F.,'chkEn','chkDis')"   
     .colSMS.DynamicCurrentControl = "iif(.F.,'chkEn','chkDis')"   
     .colTwitter.DynamicCurrentControl = "iif(.F.,'chkEn','chkDis')"   
ENDWITH

However, csrOperators is not even used. The grid's column uses a combobox with RowSourceType = 3 and the RowSource =
'select * from csrOperators into cursor cTemp'

I want to enable / disable checkboxes based on the selected operator (the EMail, etc. fields are in the csrOperators and cTemp).

Will it work adding (iiif (seek(GridAlias.op_Code, 'csrOperators','op_code') and not empty (...)

e.g. do you think adding SEEK here will help?
