Sorry was being lazy when typing, it was an empty array... The Grid wraps the GC in a HV and what I noticed was once it got passed the GC with an empty array it would always show the HV lenght was 0 even though subsequently the GC contained an array with length 1.
Then when you drag resize a column you end up in updateproperties and this time the collection variable has gone to null and the HV gets sort of rebuilt and finally recognises the GC has data and everything is fine. --- In [email protected], Scott - FastLane <[EMAIL PROTECTED]> wrote: > > Were you passing null in to the data provider or an empty array.
