VB.NET รบกวนช่วยทีคับไม่รู้ว่าผิดหรือถูกตรงไหนการโชว์ข้อมูลใน texebox

 Private Sub getData(ByVal user As String)
        Dim CondStr As String = ""
        Dim dt As New DataTable()
        Dim connStr As String = ConfigurationManager.ConnectionStrings("testConnectionString").ConnectionString.ToString()
        Dim conn As New SqlConnection(connStr)
        conn.Open()
        Dim sqlCmd As New SqlCommand("SELECT * from TABLE WHERE Table_Registration = @usersID", conn)
        Dim sqlDa As New SqlDataAdapter(sqlCmd)

        sqlCmd.Parameters.AddWithValue("@usersID", user)
        sqlDa.Fill(dt)
        If dt.Rows.Count > 0 Then
            txt_B_Name.Text = dt.Rows(0)("B_Name").ToString()   
            txt_B_numberTeL.Text = dt.Rows(0)("B_numberTeL").ToString()

        End If

        conn.Close()
    End Sub
