I want to display the registration database in the same webpage where user registers. I can display by using the listview by configuring the database with it.

Another problem is even after i added the reference for the `listview (system.web.ui.webcontrols)` the Visualstudio says its ambiguous when i type listview.

my code is below

```
        public void Insertfunc()//inserting into database 
        {
            string database = @"Data Source=.;Initial Catalog=NewDB;Integrated Security=True";
            SqlConnection myConn = new SqlConnection(database);
            string queryStr = @"insert into Registration values (@fname,@lname,@dob,@emailid,@uname)";
            SqlCommand myCommand = new SqlCommand(queryStr, myConn);
            myCommand.Parameters.AddWithValue("@fname", FirstName);
            myCommand.Parameters.AddWithValue("@lname", LastName);
            myCommand.Parameters.AddWithValue("@dob", DateofBirth);
            myCommand.Parameters.AddWithValue("@emailid", Mailid);
            myCommand.Parameters.AddWithValue("@uname", UserName);
            myConn.Open();
            myCommand.ExecuteNonQuery();
            myConn.Close();

            string query = @"select * from Registration";
            SqlCommand mycommand1 = new SqlCommand(query,myConn);
            SqlDataReader tbl = mycommand1.ExecuteReader();
// i just want to add the listview coding here 

        }

    }

    protected void Page_Load(object sender, EventArgs e)
    {

    }

    public void Submit_Click(object sender, EventArgs e)
    {
        UserRegistration User1 = new UserRegistration();
        int flag = 0;

       User1.Mailid = mailid.Text;
       User1.UserName = UN.Text;
       User1.FirstName = FN.Text;
       User1.LastName = LN.Text;
       User1.DateofBirth = DOB.Text;
     if (User1.Validatefunc(User1.Mailid, "[Email]") == true)
        {
            IDlbl.Text = "Provide Someother mailid";
        }
        else
        {
            IDlbl.Text = "Okay";
            flag = 1;

        }

        if (User1.Validatefunc(User1.UserName, "[Username]") == true)
        {
            UNlbl.Text = "Username Not Available";

        }
        else
        {
            flag++;
            UNlbl.Text = "Username Available";
        }
        if (flag == 2)
        {
            User1.Insertfunc();
        }

    }

}

```
