I am using Northwind database. How can I  display msgbox when the record is not found?


Private Sub ToolStripButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton1.Click

        Dim connectionString As String = "Data Source= SUPERMAN;Initial Catalog=Northwind;Integrated Security=True"
        Dim con As New SqlConnection(connectionString)
        Dim selectSQL As String = "select *from orders where orderid = '" & Me.ToolStripTextBox1.Text & "'"
        Dim da As New SqlDataAdapter(selectSQL, con)
        Dim ds As New DataSet


        If Me.ToolStripTextBox1.Text = Nothing Then
            MessageBox.Show("Please enter OrderId", "Empty Field", MessageBoxButtons.OK, MessageBoxIcon.Information)



        Else


            da.Fill(ds, "orders")
            Me.DataGridView3.DataSource = ds.Tables("orders")

        End If

       

    End Sub
