var controlId = ((LinkButton)gridView1.Rows[0].FindControl("lbName")).Id;

Are you trying to do something like the above?

Update
You can use the OnSelectedIndex event for the GridView to find the selected row.

  void GridView_SelectedIndexChanged(Object sender, EventArgs e)
  {
    // Get the currently selected row using the SelectedRow property.
    GridViewRow row = CustomersGridView.SelectedRow;

    var controlId = ((LinkButton)row.FindControl("lbName")).Id;
  }
