I have an editable DataGrid which displays two columns, date
and value. Now, the date in the dataProvider is actually stored as
an integer (yyyymmdd) so I format it using a labelFunction to
display. I then have a custom itemEditor to set it to a date for
calling into the DateField.
The next step, and where I'm struggling, is to update the
dataProvider with an integer (yyyymmdd) calculated from the
selectedDate. Can someone please help me with how to do this?
