2 step problem: Share info between 2 user controls on a page, Display info in a scrolling list or gridview?
<p>I have a page with multiple user controls on it. In one user control, I have a set of checkboxes that set filters on what to display in a tree view, also in the same user control. In another user control, I have a list view (or gridview, haven't decided yet) That needs to display some information based on the filters that are defined, and the tree node selected in the previous user control.</p>

<p>The listview, or gridview, needs to scroll, displaying X(say 10) amount of records at a time. Depending on what the user has selected, there can be up to 28,000 records to display, so we only want to go to the database to get a small amount of records at a time, and update the list on the fly.</p>
