Hi,

I'm trying to insert by code a new record to a datagrid control, and show
this new record. My datasource is an ArrayList. The code is the following:

i = is the position of the new ArrayList item
fCurrencyManager = (CurrencyManager)datagrid.BindingContext[theArrayList];
datagrid.DataSource = theArrayList;
fCurrencyManager.Position = i; // the grid will be pointing to i
datagrid.CurrentRowIndex = i;
datagrid.Select(i); // I want this new row to be highlighted

But the last line of code throws a System.Exception:Exception; message:
"Exception". If the i row was present since the grid was first populated,
this code works as expected.
What can be wrong?

I'm using VS2005 with emulator for PPC2003

Thanks in advance
Sammy
 
ArrayList does not have ListChanged event so DataGrid would never know
you've just added a row.

And of course you could not select row which is not in the grid from grid's
point of view.



Please consider using another data source which has ListChanged event (e.g.
BindingList), extend ArrayList with this event or rebind each time item is
added/changed/removed.


Best regards,

Ilya
