Select the DataGridView in designer mode and examine the entries under the Events tab in the properties panel. You will see events like

CellClick
CellEnter
CellLeave
etc.

One of them should be what you are looking for.

An example :

Private Sub DataGridView1_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick
    Dim i As Integer = DataGridView1.CurrentRow.Index
    With DataGridView1
            If DataGridView1.Item(0, i).Value = "1" Then
                textbox1.text="hello"
            End If 
    End With
End Sub
