    I am currently using the latest release of the RadControls (2009 SP2).  I am trying to create a chart dynamicall but whenever it hits the following line, chart.DefaultView.ChartArea.DataSeries.Add(dataSeries), the application freezes and its just a white screen.  There are similar posts about this that says this was fixed in a previous release.  Can you tell me if this is still a bug or if I am doing something wrong.

                    // Create a new Chart element.  
                    RadChart chart = new RadChart();  
                    // Set some chart defaults.  
                    chart.DefaultView.ChartArea.AxisX.StripLinesVisibility = Visibility.Collapsed;  
                    chart.DefaultView.ChartArea.AxisY.MajorGridLinesVisibility = Visibility.Collapsed;  
                    // Create a new DataSeries.  
                    DataSeries dataSeries = new DataSeries();  
                    // Add some hardcoded data points.  
                    Dictionary<string, double> dataPoints = new Dictionary<string, double>();  
                    dataPoints.Add("A", 0.121127226879971);  
                    dataPoints.Add("B", -0.511961779733487);  
                    dataPoints.Add("C", -0.394865386295022);  
                    // Add the datapoints.  
                    foreach (var point in dataPoints)  
                        // Create a new DataPoint.  
                        DataPoint dataPoint = new DataPoint();  
                        dataPoint.XCategory = point.Key;  
                        dataPoint.YValue = point.Value;  
                        // Add DataPoint to DataSeries.  
                    // Set the type of graph to draw.  
                    dataSeries.Definition = new BarSeriesDefinition();  
                    // Add DataSeries to Chart

    Hello MW,

    I was not able to reproduce this problematic behavior. Please, find attached my sample application which uses exactly your code. I would ask you to download the latest internal build from your customer account and in case the problem persist, please, prepare and send us a sample project which we could further examine and provide a solution.
