There is a DataGridView dgv ,

  dgv.DataSource = myDateTable;

There is a line selection code

 private static void SelectRowByOrderID(DataGridView dgv, string orderID) { dgv.Rows .OfType<DataGridViewRow>() .Where(x => (string)x.Cells["#"].Value == orderID) .ToArray<DataGridViewRow>()[0] .Selected = true; }

Actions:

  • select row X;
  • open the edit form;
  • save changes in the database;
  • close the edit form;
  • update myDateTable table
  • update dgv.DataSource

Question:

  • how after dgv update select line x?
  • What is the problem to cause this method after updating dgv ? - default locale
  • I do not know what event to register - Aleksandr H.
  • And where do you update dgv.DataSource ? Why is it impossible to immediately select lines there? - default locale
  • @AleksandrH. how do you update dgv? Directly dgv or through changes myDateTable? - Arantler
  • @Arantler, through the change myDateTable (read from OleDbDataReader ), is not an ObservalableCollection . At the moment, I decided this way: after the editing form is closed, the method is called, which reads the data from the database again, draws the grid, moves the cursor to the X line. Now the question is: how not only to move the cursor to the X line, but also to restore the vertical level after the update scrolled. - Aleksandr H.
