The problem. I have a popup calculator that I use to calculate the value to enter into a dbgrid. It works well for a specified field but I want it to work for any field identified by the column fieldname.

Eg:
field_name_variable := dbgrid.fieldname (for the current column)
value_variable := [some calculated result from the popup calculator]
tablename.field_name_variable.value := value_variable.

I do not know the syntax for assigning the fieldname from the field_name_variable.

Use fieldbyname
field_name_variable := dbgrid.fieldname (for the current column)
value_variable := [some calculated result from the popup calculator]

tablename.edit;
tablename.FieldByName(field_name_variable).Value := value_variable.
tablename.post;
