// Everything works fine in OnInitialUpdate() where I send data from 3-d int array to the grid...
// However I want to set the grid cell text to a combo item.
// I want to send the index selected into an int 2-d array when command button is executed.
// I want the grid cell text set by the combo box to be sent to a CString 2-d array when button is executed....
