For one of the columns in my datagrid if the value is null or
undefined then I want it to write 0 in there otherwise it should
have the dataprovider value. That column is eidtable also. Do I
have to use item renderer for this? if yes can you give me an
example. I tried doing it but didn't work.
you might be able to use the labelField for the display of
the value - from reading the language reference, it says you can
use both a datafield and label field and the labelField would be
used for display and the dataField would be used for sorting.
It would be a lot simpler than using a renderer, hopefully.
