Adding a new row to a DataGridView

[flynn]

I am trying to add a new row to a BOUND DataGridView control. The "AllowUserToAddRows" property is set to false (the user must right click the grid, then select "New Row" from a context menu).

 

private void AddNewContactLineToGrid()
{
   // deselect the currently selected row
   if (dgvContacts.SelectedRows.Count > 0)
       dgvContacts.SelectedRows[0].Selected = false;

   // add a new row to the underlying table, which will add a row to the data grid view
   dsCustomer.Tables["customer"].Rows.Add(dsCustomer.Tables["customer"].NewRow());

   // the following line throws an exception            
   dgvContacts.CurrentCell = dgvContacts.Rows[dgvContacts.Rows.Count - 1].Cells[1];
}

 

 

The "add" portion of the function works, but when I try to change the CurrentCell to the first visible column of the newly added row (I want to go into edit mode as soon as the new row is added), I get this error:

 System.InvalidOperationException was unhandled. Operation did not succeed because the program cannot commit or quit a cell value change.

 

A Google search on this message (and small subsets of it) returned nothing. Does anyone have any ideas?

 

The stack trace:

System.InvalidOperationException was unhandled

Message="Operation did not succeed because the program cannot commit or quit a cell value change."

Did you get this sorted out? I'm seeing the same problem in C++/CLI.
