Hi,
Is there ANY WAY to hide a row/field in a DetailsView based on meeting a
condition at the ItemCreated or ModeChanging event -- or any other way?
There appears not to be, but I was hoping for confirmation before
totally giving up.
Thanks,
Kit

actually, after re-reading your post, you want to see how to not show
fields programatically. I did that first and then confused myself to
think you wanted just the other. So, a few control-z's and this has
an example of both getting rid of a field and of getting rid of a
complete attribute. To hide the field, you just set the visible
property of the column in the template.
Good luck and here is the code again with some extra stuff.
