I have a ScriptManager w/ partial rendering enabled.&nbsp; What happens is the UpdateProgress graphic will show up when I change the selection of the drop down list (like it&#39;s posting back), but 1) the UpdateProgress never goes away, and 2) the DataList is never updated...so everything in the UpdatePanel is not being updated, and I don&#39;t know why :-(</p><p>&nbsp;</p><p>Does anyone have a clue why this would be occurring?&nbsp;
