When I run your code, the delete executes without the confirmation.  When you say (in your code comment) to add to ClientClick, where and how is that set.  I think you mean in the DetailsView asp code, but I do not see ClientClick as an option.  I see "OnItemCommand" or "OnItemDeleting".  Would one of these be used?  If so, what do I set it equal to?  Or do I need to set it to the LinkButton ClientClick in asp?  With the AutoGenerate option, the command rows or LinkButtons are not explicitly stated.  The only asp reference I see to the LinkBUttons are AutoGenerateDelete="True", etc.  

Here is my code....hope it helps....
