Description

This article shows how to identify a datapoint of a RadBarSeries in RadChartView when clicking on a specific bar.

Solution

To achieve this, handle the MouseClick event of RadChartView and use the HitTest method to detect the datapoint associated with the clicked bar. Here is the code example:

C#

this.radChartView1.MouseClick += RadChartView1_MouseClick;

private void RadChartView1_MouseClick(object sender, MouseEventArgs e)
{
    foreach (var s in this.radChartView1.Series)
    {
        Telerik.WinControls.UI.BarSeries barSeries = s as Telerik.WinControls.UI.BarSeries;
        if (barSeries != null)
        {
            DataPoint dp = barSeries.HitTest(e.Location.X, e.Location.Y);
            if (dp != null)
            {
                Console.WriteLine(dp.Label); // Outputs the datapoint label
            }
        }
    }
}
