Hello all,
I've got an UltraWinGrid that's data-bound to a BindingSource:
bindingSource.DataSource = new List<MyDataObject>();ultraGrid1.DataSource = bindingSource;
After I add (866) items to the list using a background worker thread:
foreach (var item in itemsList){ bindingSource.DataSource.Add(item);}
I get the exception below. It doesn't happen with any consistency. Sometimes it works just fine. Any ideas what's going on?
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

You need to make sure that you marshal any asynchronous calls back to the main UI thread when dealing with anything that could affect the UI; this is true of all UI aspects in .NET, as far as I am aware. The fact that this doesn't always happen at the same time is a classic symptom of a threading issue. In this case, you're updating the data source, which is then sending a notification to the grid that it has changed; the grid will respond to this by asking for the value and updating itself, so you are indirectly affecting the UI from another thread.
-Matt
I came to the same conclusion last night and my workaround was to update the datasource in the ProgressChanged event handler, which would guarantee that updates to my datasource would happen in the same thread as the UI thread.
If I were to go the route that you suggested, i.e. synchronizing the update of the data source between the background thread and the UI thread, how, or where really, would I do it? I figure it would be something like:
lock (_lockObject) { bindingSource.DataSource.Add(item); }
But where I'm lost is what do I synchronize on the UI thread and where? Would it be in the AddingNew event for the binding source? Thanks for your help so far Matt.
