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:
