Changing ChartControl.Properties by code throws exception

[cls71]

Hello,

When I use this code to modify the properties of the chartcontrol I get a directx exception, which freezes the application and I have to kill the process to exit.

private void setChartControlProperties()
        {
            if (this.ChartControl != null && this.ChartControl.Dispatcher != null )
            {
                this.ChartControl.Dispatcher.InvokeAsync(new Action(() =>
                {
                  this.ChartControl.Properties.ChartBackground = new SolidColorBrush(myconfig.ChartControlBackground.Value);
                  this.ChartControl.Properties.AxisPen = new Stroke(new SolidColorBrush(myconfig.ChartControlAxisColor.Value), ConvertDashStyle(myconfig.ChartControlAxisDashStyle), myconfig.ChartControlAxisWidth);
                  this.ChartControl.Properties.GridLineHPen = new GridLine(new Stroke(new SolidColorBrush(myconfig.ChartControlGridHorizontalColor.Value), ConvertDashStyle(myconfig.ChartControlGridHorizontalDashStyle), myconfig.ChartControlGridHorizontalWidth), myconfig.ChartControlGridHorizontalEnabled);
                  this.ChartControl.Properties.GridLineVPen = new GridLine(new Stroke(new SolidColorBrush(myconfig.ChartControlGridVerticalColor.Value), ConvertDashStyle(myconfig.ChartControlGridVerticalDashStyle), myconfig.ChartControlGridVerticalWidth), myconfig.ChartControlGridVerticalEnabled);

                  this.ForceRefresh();
                }));
            }
        }

The exception message is:

Is there any way to modify the chartcontrol.Properties by code ?

Thanks very much.

TriggerCustomEvent(o =>
            {
                Brush b = new SolidColorBrush(myconfig.ChartControlBackground.Value);
                b.Freeze();
                chartProperties.ChartBackground = b;
            }, 0, null);
