Try This with lambda

Private Sub dgv_pararelhp_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles dgv_pararelhp.EditingControlShowing
    If dgv_pararelhp.CurrentCell.ColumnIndex = 0 Then'// change this optional your index column.
         AddHandler CType(e.Control, TextBox).KeyPress, Sub(s_, e_)
                                                            If Char.IsDigit(CChar(CStr(e_.KeyChar))) = False Then e_.Handled = True
                                                         End Sub
       End If
End Sub
