C#, Database connection error

Good Morning all,

I am writing a test program to connect a C# WinForm to a test database .SDF file. I have managed to populate the database and make it show up in a datagridview already but now I am trying to add data during runtime. At first I am hard coding the values to add but when I do it I get an error about the User ID. I am not sure what to code for it because when I created the database no user ID was defined only the password. Here is my code

 

SqlCeConnection sqlConnection1 = new SqlCeConnection();
            sqlConnection1.ConnectionString = "Data Source = C:\\Users\\smunsell\\Documents\\TestDB.sdf; User ID = ???; Password = Password";

            System.Data.SqlServerCe.SqlCeCommand cmd = new System.Data.SqlServerCe.SqlCeCommand();
            cmd.CommandType = System.Data.CommandType.Text;
            cmd.CommandText = "INSERT [UserData] (ID, User, Status) VALUES ('12', 'Tim', 'Inactive')";
            cmd.Connection = sqlConnection1;

            sqlConnection1.Open();
            try
            {
                cmd.ExecuteNonQuery();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }
            sqlConnection1.Close();

Select allOpen in new window

Any ideas how to fix it or what I should put in my uer id? Screenshot of program attached. Error code as well.
