My XamChart as 3 series which is binded with this.DataContext (CurrentPriceObj.PriceTrend which is a DataTable). When I got the onChange event fire I Invoke CurrentPrice .doCalculation which is simply adding a datarow. I pass back the datatable to a new LivePrice Class and invoke the new this.DataContext.

Everything works like a charge until this. Since the XamChart has a limited number or point that can be seen, I have to remove some datarow in my datatble during doCalculation. I Accept the changes of course and my XamChart does not appear anymore. And I do not have any error poping up.

What could possibly be wrong.

void _onChange(Addin_MktPrice_Interface.Change Changes)
        {
            try
            {
                
                    CurrentPrice.RealPrice = (Addin_MktPrice_Interface.MarketPrice)Changes.Values;
                   
                    this.Dispatcher.BeginInvoke(new Action(() => CurrentPrice.doCalculation()), null);

                    LivePrice CurrentPriceObj = new LivePrice();
                    CurrentPriceObj.PriceTrend = CurrentPrice.PriceTrend;
                    
                    this.Dispatcher.BeginInvoke(new Action(() => this.DataContext = CurrentPriceObj), null);
                   

                    GC.Collect();
                    GC.WaitForPendingFinalizers();
                    GC.Collect();

            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message + "\n" + ex.StackTrace);
            }
           
        }
