Export CSV GridComboOption value is exported not the Text

Hi
I’m trying to Export my TreeGrid to CSV using provided Serialize API, but the problem is i have GridComboOption as a column in my grid for that column it exports selected GridComboOption value, but i want to Export selected option Text instead of value. Is there any custom serializer at column level to get Text instead of option value.
my code is :
mygrid.serializeToCSV()

Thanks

Unfortunately this is the designed behavior. serializing process works with the values of the cells. it is not available to serialize the test of the of the formatted cell.
