Попробуй вот так.

Imports System.Data.SqlClient
Public Class Form1
    Dim connetionString As String
    Dim connection As SqlConnection
    Dim adapter As SqlDataAdapter
    Dim cmdBuilder As SqlCommandBuilder
    Dim ds As New DataSet
    Dim changes As DataSet
    Dim sql As String
    Dim i As Int32

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        connetionString = "Data Source=ServerName;Initial Catalog=DatabaseName;User ID=UserName;Password=Password"
        connection = New SqlConnection(connetionString)
        Sql = "select * from Product"
        Try
            connection.Open()
            adapter = New SqlDataAdapter(Sql, connection)
            adapter.Fill(ds)
            connection.Close()
            DataGridView1.Data Source= ds.Tables(0)
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
    End Sub

End Class
