Occurs in Asp.Net WebSites in the code files for aspx pages. Not sure if the same thing occurs in WebProject code behinds.

UserControl Example:
A Web Form named (and in folder) Members\Welcome.aspx is created.

A UserControl named (and in folder) UserControls\SearchRequirements.ascx is placed on the page and given the id 'requirementsSearch'.

Intellisense popup after dot on all references to the instance shows "No suggestions".
Any property or method of the user control instance 'requirementsSearch' will be highlighted as an invalid symbol.

The instance itself is not highlighted as an error but the tooltip shows that ReSharper is not recognizing it correctly.
The tooltip text is "(field) ASP.usercontrols_searchrequirements_ascx Members_Welcome_requirementsSearch"


Ajax Toolkit Control Example:
A Web Form named (and in folder) Members\Welcome.aspx is created.

An UpdatePanel is placed on the page and given the id 'searchResults'.

Intellisense popup after dot on all references to the instance shows "No suggestions".
Any property or method of the update panel instance 'searchResults' will be highlighted as an invalid symbol.

The instance itself is not highlighted as an error but the tooltip shows that ReSharper is not recognizing it correctly.
The tooltip text is "(field) __ReSharper_TagPrefix_ASP.UpdatePanel Members_Welcome_searchResults"


At first I thought the problem was only with the Ajax Toolkit controls and the UserControls that were not recognized were doing so because they have Ajax Toolkit controls on them. I think I have found some instances where that may not be true, but I will need to investigate more. I see the errors with both UserControls and Ajax Toolkit Controls on the same page.
