Hi!

I am trying to make a simple edit in one of my reports using report designer.

I try to configure the data source in order to test it but i cant do it since the dropdown box is empty. SQL Server connectivity tools are installed.

This is not happening to only one machine

Here is a picture of the application: IMAGE

Hello Elias,

Please check our Data provider is missing in the SqlDataSource wizard KB article and verify data providers are installed and registered correctly on the machines, and there are no issues with the providers factory.

The problem lied in the machine.config file for one of the .NET framework versions (x64 v4.0 for me).

Along with the normal entries for <DbProviderFactory> and after them there is a blank entry like this:

<DbProviderFactory/>

Just remove it from everywhere you find it.
