TypeName property of ObjectDataSourc e Not Found

I've got a simple (I think) asp.net application.

I've created a DataSet in App_Code/ItemDataSet.xsd . Tested connection,
seemed to work fine.

In my ASPX file, I first dropped an ObjectDataSourc e onto the form, and
pointed it to the dataset created above.

I then dropped a GridView on the form, and selected the ObjectDataSourc e
I created above. In the Design view it seems to be at least loading the
columns (if not the data) correctly.

When I try to access on the server, I am getting the following error
(full stack trace at bottom of message):

[InvalidOperatio nException: The type specified in the TypeName property
of ObjectDataSourc e 'ObjectDataSour ce1' could not be found.]

Thanks for any insight.

here is my aspx code:

I've got a report that is using an ObjectDataSource to populate its data. The problem is that the report takes longer than 30 seconds to generate so it times out. If I were using an SQLDataSource object I know how to set the Command.Timeout to account for this but I can't find the Timeout...
