Question

Here is my scenarion:

I have a GridControl bound to a BindingList. At first what I was doing was creating a worker thread and access the BindingList directly, but th

Just in case someone has run into the same problem... I managed to fix it after some hours. Here is what I did:

Basically the problem was that the object implementing INotifyPropertyChanged was living in a worker thread, and this causes problems when accessing the UI thread.

So what I did was pass a reference to the object that needs to be updated to the INotifyPropertyChanged object, and then use invoke on it.

Here is what it looks like:

    public event PropertyChangedEventHandler PropertyChanged;

    protected void OnPropertyChanged(string name)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
        {
            //If the Proxy object is living in a non-UI thread, use invoke
            if (c != null)
            {
                c.BeginInvoke(new Action(() => handler(this, new PropertyChangedEventArgs(name))));
            }
            //Otherwise update directly
            else
            {
                handler(this, new PropertyChangedEventArgs(name));
            }

        }
    }

    //Use this to reference the object on the UI thread when there is need to
    public Control C
    {
        set { c = value; }
    }

From the thread, all I did was:

                    prox.c = this;
                    //Logic here
                    prox.c = null;

Hope this helps someone!!
