The edit value for a key pad cell is the value that is passed to the Aria edit event management system. This may be different than the displayed text of the cell or when the cell is using a picture icon and has no display text. 

An input string that references the string table is a valid use case and the edit text will change as the active string table language changes.

LIB_EXPORT laResult laKeyPadWidget_SetKeyValue(
    laKeyPadWidget* pad, 
    uint32_t row, 
    uint32_t col, 
    laString str
);

laResult - the result of the operation
