Any idea what this might be? I have a combobox populated via BO bound to a field in my "master" BO. I can view, navigate, edit, just not add......



Thanks.





IndexOutOfRangeException

There is no row at position -1.

I figured that was the case as this is when we custom render.

It is...but I am using it in a ton of places in our medical app and as of yet, I have not seen this...but I do believe you   I will keep trying on my end to reproduce.

I am glad that this has worked out for you.  This should not have any bearing on this particular issue though.

Just as a final thought, you DO have the combo populating with a value for each column, correct?
