Script controls may not be registered before PreRender
posted

I'm adding a WebDropDown control to an existing page and get an error stating "Script controls may not be registered before PreRender"  The page works prior to dropping the control on the form and I've not yet written any code accessing the WebDropDown.  Simply dropping the control on the form and accessing the page causes the error.  The page includes a ScriptManager and inherits from a PageBase class. 

I'm using NetAdvantage 9.1 in VB 2008.
