I have tried to assign the currentcontrol to the optiongroup. When executed at the first time, there is no problem. However, after that, problem occured. An error message shows "Expression evaluated to an illegal value", when I did not addobject'ed an optiongroup programatically.(I have inserted an optiongroup into the grid when GRAPHICALLY implemented the form.)

Another way I tried was to issue an addobject command to add the optiongroup, and removeobject the textbox which was initially set as default control. Also I assigned the currentcontrol properties to the optiongroup. However, it did not work either, leaving gray shadow on the column.

Even only a refresh() method was triggered, the problems occurred.

Any comments about this?
