retrieving multiple data from one column using vb.net

I m new to asp.net is there any way that i could display different data in one row where the data is pulled from same column of another table? where the column is name hello and contains 3 types of data let`s say my code is like this:

    cmd1.CommandText = " SELECT hello FROM link where mode=@model and procedure =@procedure "
    cmd1.CommandType = System.Data.CommandType.Text
    Dim da1 As New SqlDataAdapter()
    da1.SelectCommand = cmd1
    Dim dt1 As New DataTable()
    da1.Fill(dt1)
    Dim myDataReader1 As SqlDataReader
    myDataReader1 = cmd1.ExecuteReader()
    Dim hello As String
    If myDataReader1.HasRows Then

        Do While myDataReader1.Read()
            hello= myDataReader1("hello").ToString()

        Loop
        lblhello.Text = hello
    Else
        lblhello.Text = ""
    End If


    myDataReader1.Close()  

my data output should be like:

but i ended up getting

heyhey
