How to get bind data item from the clicked column element of Column chart.
posted

I am using XamWebChart Column Chart of Silverlight controls v 10.2. Here on user click on column of column chart i want to get the bind item of the column. I tried DataItemMouseLeftButtonDown event by following post from infragistics forum:

https://ko.infragistics.com/community/forums/f/retired-products-and-controls/36069/how-to-get-the-datapoint-value-in-line-splinearea-doughnut-charts/210089#210089

https://ko.infragistics.com/community/forums/f/retired-products-and-controls/41956/xamwebchart-line-chart-tooltipdate-value-and-performance-issue/235429#235429

But still didnot get the sucess. on DataItemMouseLeftButtonDown event e. element is of type "ColumnChartDataPointTemplate" and "(e.element as ColumnChartDataPointTemplate).Tag always return null.

Also (e.Element as ColumnChartDataPointTemplate).PointIndex always return 0 instead of clicked item index.

Please help me for the same.

    Hi jainnitin,

    Since you are using a Column Chart, you should simply be able to do this on your MouseLeftButtonDown event:

    private void Chart1_DataItemMouseLeftButtonDown(object sender, Infragistics.Silverlight.Chart.DataItemMouseEventArgs e)
        {
            DataPointTemplate shape = e.Element as DataPointTemplate;

            if (shape != null)
            {
                DataPoint point = shape.DataPoint;
            }
        }

    Hopefully this is what you are trying to achieve.
