Re: CheckBoxList in DataList Question?

Tech-Archive recommends: Fix windows errors by optimizing your registry

Jeremy thx for the reply.
But is doing this not enough by adding AddHandler in the ItemDataBound like
so:-
AddHandler cblGroups.SelectedIndexChanged, AddressOf
cblGroups_SelectedIndexChanged

Bcos i'm already DataBinding in the ItemDataBound.

My main question that i don't get is can i add the method
SelectedIndexChanged i have set in my checkboxllist to my

ItemDataBound by using the AddHandler?

And if not what would i have to set SelectedIndexChanged in my
DataList1_ItemDataBound and not in my CheckBoxlist.

Thanks
