[Mark]

Hi,
I have successfully created a chart with a series , but cannot seem to get tooltips visible OR item click firing?
Here is the relevant code i use...

Many Thanks
Mark

this.RadChart1.SeriesMappings.Add(seriesmapping);

this.RadChart1.DefaultView.ChartArea.ItemClick+=new EventHandler<ChartItemClickEventArgs>(ChartArea_ItemClick);

this   .RadChart1.ItemsSource = ReturnChartData;

private SeriesMapping seriesmapping()

{

SeriesMapping _seriesMapping = new SeriesMapping();

_seriesMapping.SeriesDefinition = new BarSeriesDefinition();

ItemMapping yMap = new ItemMapping("yValue0"  , DataPointMember.YValue);

ItemMapping xMap = new ItemMapping("xCategory", DataPointMember.XCategory);

_seriesMapping.ItemMappings.Add(yMap);

_seriesMapping.ItemMappings.Add(xMap);

_seriesMapping.SeriesDefinition.ShowItemToolTips = true;

return _seriesMapping;

}

private void ChartArea_ItemClick(object sender, ChartItemClickEventArgs e)

{

MessageBox.Show("asfafasfasfasfasfasfasf","my message", MessageBoxButton.OK);

}

    private List<ChartData> ReturnChartData()
    {
        List<ChartData> data = new List<ChartData>();
        data.Add(new ChartData("Toyota", 125,10,100));
        data.Add(new ChartData("GM", 192, 20, 90));
        data.Add(new ChartData("VW", 151, 30, 80));
        data.Add(new ChartData("Ford", 125, 40, 70));
        data.Add(new ChartData("Honda", 154, 50, 60));
        data.Add(new ChartData("Nissan", 79, 30, 50));
        data.Add(new ChartData("PSA", 79, 20, 100));
        data.Add(new ChartData("Hyundai", 64, 10, 46));

        return data;

    public class ChartData
    {
        public ChartData()
        {

        }
        public ChartData(string _xCategory, int _yValue0, int _yValue1, int _yValue2)
        {
            this.xCategory = _xCategory;
            this.yValue0 = _yValue0;
            this.yValue1 = _yValue1;
            this.yValue2 = _yValue2;
        }
        public ChartData(string _xCategory, int _yValue0, int _yValue1)
        {
            this.xCategory = _xCategory;
            this.yValue0 = _yValue0;
            this.yValue1 = _yValue1;
        }
        public ChartData(string _xCategory, int _yValue0 )
        {
            this.xCategory = _xCategory;
            this.yValue0 = _yValue0;
        }
        public string xCategory
        {
            get;
            set;
        }

Hi
I have answered my own question again.

On my page i had a textblock which was declared after the chart. The textblock had no size set, so i assume it was covering the chart (hence the tooltip and click not working). I removed the textblock and all is working ok now.
