Hi all,

I have a usercontrol that doesn't contain a control. When I try to
drop the control on a form I get an error:
Failed to create component'TestcaseUserControl'. The error message
follows: 'System.NullReferenceException: Object reference not set to
an instance of an object.' at Line 20

Line 20 is: TestService m_service = new
TestService(ConfigurationManager.ConnectionStrings["connectionString"].ToString());

I also get compile warning:
- Exception has been thrown by the target of an invocation.

When I remove TestService m_service = new
TestService(ConfigurationManager.ConnectionStrings["connectionString"].ToString());
from the class it works.

Someone knows what's wrong?

Thanks
Stijn

public partial class TestCaseUserControl : UserControl
{
    public TestCaseUserControl()
    {
        InitializeComponent();
        TestService m_service = new
TestService(ConfigurationManager.ConnectionStrings["connectionString"].ToString());
    }
}
