You can bind your dataSource to dataGridview and TextBoxes.

Here is sample code (Add dataGridView1, TextBox1,TextBox2):

 Private Sub YourForm_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        Dim dt As New DataTable
        dt.Columns.Add("No")
        dt.Columns.Add("Name")

        dt.Rows.Add(1, "A")
        dt.Rows.Add(2, "B")

        DataGridView1.DataSource = dt

        TextBox1.DataBindings.Add("Text", dt, "No")
        TextBox2.DataBindings.Add("Text", dt, "Name")
    End Sub
