Hi Alex
I had looked on your site originally but missed the CheckBoxList And
DataGrid example the first time.
Now that I look at that I notice that I missed out (I'm an idiot):
super.data = value;
invalidateProperties();
at the end of the set data override - now that I have added that in
it all works just fine.
Thanks very much for your help and I will be back to your site again
for more info on editors when I get to that point.
Cheers
Chris
