Did you try to bind your grid after calling DeleteRow function?

My understanding is that you have a datagridview bound to a database and user enters new rows and your problem is if the user enters a wrong data, you should be able to highlight the row in the datagrid view and delete it by a click of a button ?

If that is the case, you can do the following - "dg" is the name of my datagridview

C#

private void button1_Click(object sender, EventArgs e)
      {
          try
          {
              dg.Rows.Remove(dg.CurrentRow);
          }
          catch (Exception ex)
          {
              MessageBox.Show(ex.Message);
          }
      }
