I was doing some testing on delegation. I set the data row limit for non-delegable queries to 3.
I then add a dropbox and link to a Sharepoint list. When I click on the control, it only list 3 items.
Sharepoint list is delegable but I'm puzzled why I'm only getting 3 items displayed.
What is your Items property like for your dropdown control?
If you are using a non-delegable function in it, that would account for the limit.
So, I'm not entirely sure what issue you are having though.
If you've set the data limit to 3, then 3 is all you're going to get.
