If I change a the Font of single Text primitive within the ChartDrawItem event-handler, this affects *all* Text primitives drawn afterward. How can I prevent this?

For example if I have a GanttChart with 4 entries:

GanttDataSource ganttData = new GanttDataSource();
GanttSeries ganttSeries = ganttData.Series.Add("Series A");
ganttSeries.Label = "";
GanttItem task1 = ganttSeries.Items.Add("Task 1");
GanttItem task2 = ganttSeries.Items.Add("Task 2");
GanttItem task3 = ganttSeries.Items.Add("foo");
GanttItem task4 = ganttSeries.Items.Add("foo2");
series = ganttSeries;
xAxis.Labels.Orientation = TextOrientation.VerticalLeftFacing;
xAxis.Labels.ItemFormatString = "<ITEM_LABEL:MMM dd, yyyy>";
yAxis.Labels.ItemFormatString = "<ITEM_LABEL>";
chartLayer.ChartType = ChartType.GanttChart;
SetAxisTypes(chartLayer);
this.UltraChart1.Series.Add(series);
chartLayer.Series.Add(series);
UltraChart1.ChartDrawItem += new Infragistics.UltraChart.Shared.Events.ChartDrawItemEventHandler(UltraChart1_ChartDrawItem);


and then want to change the font of only foo I try:


void UltraChart1_ChartDrawItem(object sender, Infragistics.UltraChart.Shared.Events.ChartDrawItemEventArgs e)
{
    if (e.Primitive is Text)
    {
        Text text = (Text)e.Primitive;
        if (text.GetTextString() == "foo")
        {
            text.labelStyle.Font = new Font(FontFamily.GenericSansSerif, 15, FontStyle.Bold);
        }
    }
}

but the result is that both "foo" and "foo2" are now in style 15pt Bold. I only want text.labelStyle.Font to affect the single item I have in ChartDrawItem, how can I do this?

Thanks
