Hi,

What is the exact error message? Can you trap it with Try-Catch?

Are you doing Postback in your Page_Load?

A suggestion is to not use SetDatabaseLogon to log the report onto the database server, instead try using LogOnInfo. SetDatabaseLogon has some limitations and LogOnInfo is more reliable. LogOnInfo has to be set for each table in the report.

If you go to the SDK forum and search for LogOnInfo you will find a few samples.

Good luck,
