Hi,
I'd create the DetailsView dynamically (add them to a placeholder). Use a
DataView filter to display the desired data. Here's the code below.
Let us know if this helps?

Guys,
I am trying to created a detailview that displays several records at a
time.
Let's say I have a GridView with checkboxes and when I check two
checkboxes
and click a button, I want it to give me two DetailViews; one for each
record selected. how can I do this? Or is there a better way than this?
