Working with multiple .cs documents, passing data back and forth

[DeepThought]

[.Net 4.0]

Hello,

I have multiple .cs documents in the same project. The first project I was able to pass data back and forth by creating a public string function. But for some reason in my new one I am missing something. I using the same namespace name for all .cs documents.

In MainWindow.xaml.cs I have this function:

public string whatis_SQL()
{
return SQLServerName.Text;
}


In Backup.xaml.cs when I try to run the following it does not recognize whatis_SQL.

string selectedSQLServer = whatis_SQL();


Thanks!
