    I am doing this to manually add a ChartLegendItem:

    ChartLegendItem cli = new ChartLegendItem();
    cli.Label = data.company;
    cli.MarkerShape = MarkerShape.Circle;
    cli.Foreground = chart.PaletteBrushes[i++];
                          
    chart.DefaultView.ChartLegend.Items.Add(cli);

    And I am getting an IE error:

     Unhandled Error in Silverlight Application Object reference not set to an instance of an object. at Telerik.Windows.Controls.Charting.ChartLegendItem.get_HoverScope()

    at Telerik.Windows.Controls.Charting.ChartLegendItem.OnMouseLeave(MouseEventArgs e)

    at System.Windows.Controls.Control.OnMouseLeave(Control ctrl, EventArgs e)

    at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, String eventName)


    Any suggestions?

    Hello Jeff Kershner,

    Indeed we must admit that there was a problem when hovering user-defined legend items in the Q2 2010 version of the control, but our developers have already addressed it and you can download the latest official service pack release to get the fixed version.
