I've just installed Razden 1.15 for the first time and am trying to connect a SQL Server datasource. I have verified the connection information. The message I receive is below. Looking at the message I do not see the named instance of the sql server that I have entered in the connection information in the format: server\instance. I only see the server name in the error message.
Can Radzen connect to a named instance of SQL Server?
To connect to a named instance you should set Server as <server-name>\<instance name> e.g. localhost\SQLEXPRESS. There are a few other prerequisites:
Your SQL server should be running on TCP/IP. If the port it is running on is different from the default 1433 you should specify it in the Server field e.g. localhsot\SQLEXPRESS,8999.
SQL Server browser service should be enabled.
SQL Authentication should be enabled. Radzen doesn’t currently support Windows authentication.
I faced the same issue and not able to connect to just only restarting SQL Server Browser service. I restarted the Sql Server (Express), then it is working fine.
