UpdatePanel is not a known element

I'm getting the abovementioned error in a detail form under a master template. The code still compiles, but nearly every control has the "is not a known element" error, i.e. contenttemplate,   textbox, GridView, table, TBODY, TR, TDdiv, SelectParameters, Parameter, Font, DropDownList, ListItem, etc.

All of these controls are in an UpdatePanel.

Is this because I'm running AJAX ?. I have ScriptManager in MasterPage.master.
