It's as the title says. I can't figure out what is causing this to occur. The page in question has minimal changes made the past month, and these revolve around the addition of a new lookup control (based on RadComboBox) and some internal system logic unrelated to UI. My understanding is that if ViewState is enabled on the control, then PageIndexChanged should fire before NeedDataSource, but it does not.
The end result is paging on a grid that worked a month ago no longer works. It continues to load the first 15 records every time the page is changed.
Any thoughts? I'm sorry, I can't provide code, because this issue isn't from a simple solution. I'm mainly looking for ideas on how to debug/correct this that I haven't thought of.
