.NET อยากรู้เรื่องการใช้งาน binding nevigator กับฐานข้อมูล sql server ครับ

	Dim objConn As New SqlConnection
	Dim objCmd As New SqlCommand
	Dim dtReader As SqlDataReader	
	Dim strConnString,strSQL As String

    Sub Page_Load(sender As Object, e As EventArgs)
		strConnString = "Server=localhost;Uid=sa;PASSWORD=;database=mydatabase;Max Pool Size=400;Connect Timeout=600;"
		objConn.ConnectionString = strConnString
		objConn.Open()

		IF Not Page.IsPostBack() Then
			ViewData()
		End IF	
    End Sub

	Sub ViewData()
		'*** DataTable ***'
		Dim dtAdapter As SqlDataAdapter 
		Dim dt As New DataTable
		strSQL = "SELECT * FROM customer WHERE CustomerID = '"& Request.QueryString("CustomerID") &"' "	
		dtAdapter = New SqlDataAdapter(strSQL, objConn)
		dtAdapter.Fill(dt)
		
		If dt.Rows.Count > 0 Then
			Me.txtCustomerID.Text = dt.Rows(0)("CustomerID")
			Me.txtName.Text = dt.Rows(0)("Name")
			Me.txtEmail.Text = dt.Rows(0)("Email")
			Me.txtCountryCode.Text = dt.Rows(0)("CountryCode")
			Me.txtBudget.Text = dt.Rows(0)("Budget")
			Me.txtUsed.Text = dt.Rows(0)("Used")
		End IF
	End Sub
