Direct Connection to Local SQL express gives error

I'm just starting out here.

I created a simple formview connected to a local file copy of the database by adding the database into the project. It worked fine.

However, I noticed that this copy of the database was not synch'ing with the database with the same name in SQL express. So I created a new connections string to access the SQL database directly out of SQL express. Its just a simple Select * from column. However, this gives an error. Why?

Server Error in '/NETCatMgr' Application.

The data types ntext and nvarchar are incompatible in the equal to operator.

Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details:System.Data.SqlClient.SqlException: The data types ntext and nvarchar are incompatible in the equal to operator.

This is the connection string

<

addname="CatalogMgrConnectionString"connectionString="Data Source=mymachine\sqlexpress;Initial Catalog=CatalogSQL;Integrated Security=True"providerName="System.Data.SqlClient" />

Doesn't make sense. How can the formview work fine with the SQL integrated into the project but not working with a connection string to the SQL Express proper?

The error seems to be a data operation error other than a connection error. It indicates your code was trying to compare nvarchar value and ntext using "=" operator. Please make sure you choose proper data for comparation. To manipulate text/ntext/image data in SQL Server, you should use specific functions:

|||Its not me -- the problem appears to be some kind of bug in the GridView. The database column is a type nText and the GridView doesn't seem to be able to write code for SQL databases with column types nText. It writes the code with a string comparison and then it crashes... I didn't write any code at all.
