Dear All,
Please let me know if anybody worked on changing the database dynamically using Power BI API. If you have a sample code please pass it on.
The requirement is like this. We are having a multi-tenant C# application (Different Dbs on single Azure SQL server). We are storing all the database name in session.
I have downloaded the sample application by following the link for Power BI dashboard embeding.
https://powerbi.microsoft.com/en-us/documentation/powerbi-developer-embed-sample-app-owns-data/
The embeded dashboard is appearing fine. I would like to pass the database name dynamically based on the user login, rest of the connection parameters remains same.
data source=prasanna\\SQLEXPRESS;initial catalog=" + Session["DatabaseName"].ToString() + ";user id=yeats;password=yeats;persist security info=False;encrypt=True;trustservercertificate=True;
Thanks for your help.

You can only change the connection string of the datasource in DirectQuery mode. See below demo setting connection string or a Azure SQL Server.

What is the alternative of "SetAllDatasetConnections" as it is deprecated? I want to change the DB server name, DB name, DB user name, and password.
