Stefan #4 Re: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Hey Alvin,
Thanks for the followup ... It turns out the DataKeyField was showing
empty... So I added the DataKeyField with primary key ..
AutoGenerateColumns="False" DataSource="<%# dataSet1 %>"
DataKeyField="NewsGroupID" Visible="False" Font-Names="Arial">
If anyone has any assistance on my other error... All I have to do is get by
that error and I am done... :0) hopefully ...
Thanks
Stefan

probably not the case here but i had this same problem using Session
variables the same way you are. ie: initializing/creating them at the time
you need them. the ref books i've read say this is OK but i had problems. to
get rid of the error, i ended up having to initialize all my Session vars in
the SessionStart handler then resetting the values when necessary in my main
code.
