I have a requirement to create dynamic connection for SSRS reports where the connection information (Server & DB) will be worked out in c# code, so no interaction with end user selecting(Server or DB).
Catch here is report on its load will connect to specified DB and then populate the several other parameters like dropdowns etc at runtime using current connection.
For same i went down the route of Expression based connection string in SSRS. It all works well till i keep the "Dynamic" connection parameter type "Visible" and during report run pass the connection string from frontend which is not what i want.
How can i run report with dynamic connection from backend and then populate other parameters on report load itself?
