All, I have a master page that has a script manager added and two user controls added to content pages that each have an update panel. If I surround the entire markup of each user control with the Update Panel and content template tags everything works fine.
If I only surround a button and its label in one of the user controls (which have many text boxes, labels, etc) with the update panel/ content template none of the controls are available through intellisense and I get a red error line under each control in the .cs file that says 'textbox1 does not exist in the current context'??
