Hi all, I was able to reproduce the blank listbox with application.
It looks like it is reading connection string from web.config and not the current wizard settings.
As a workaround can you please try to manually set the same connection details as in the wizard
(Data Source=<YOURSERVER>;uid=<USER>;pwd=<PASSWORD>;database=<DATABASE>)
<
add
name
=
"LocalSqlServer"
connectionString
=
"Data Source=;uid=;pwd=;database=;Connect Timeout=90;"
providerName
=
"System.Data.SqlClient"
/>
