Mcrosoft reporting in asp.net

Question

Hi friends,

I am generating reports in my application using Microsoft reports but i am getting error as
"An error has occurred during report processing.The type specified in the TypeName property of ObjectDataSource 'ObjectDataSource2' could not be found".

Can Any one help me.

I am new to reporting and it would be very helpful if some one explain me how to generate Microsoft reports(Not Crystal reports).

Thanks
