Your first step would be to check the value of _connString after using the above code to see which one returns the right connection string, and which one throws an exception.
Just put a breakpoint on that line of code and examine the variable.

Then when you discover the right method (one of the above is correct ;-) ), step through your code, because the "can't find the source to display" will probably be a separate issue.
