I have problem with the insert statement
Error description: The type specified in the TypeName property of ObjectDataSource 'InputtableObjectDataSource' could not be found.
It's the Inputtable_add.aspx and .cs fil
I also try to place all fils in the VS 2008.

In VS 2008 I have tried to configure Datasource but the following message come up:
ERROR massage in VS 2008:
