Hello Kyle,
Thank you for writing.
RadChartView does not provide means for directly attaching a click event to the label elements. You can achieve your task by handling the MouseClick event of the control and after checking for the mouse and the labels locations:
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
public RadForm1()
{
InitializeComponent();
BarSeries barSeries = new BarSeries("Performance", "RepresentativeName");
barSeries.Name = "Series1";
barSeries.LegendTitle = "Series1";
barSeries.ShowLabels = true;
barSeries.DataPoints.Add(new CategoricalDataPoint(177, "Harley"));
this.radChartView1.Series.Add(barSeries);
BarSeries barSeries2 = new BarSeries("Performance", "RepresentativeName");
barSeries2.Name = "Series2";
barSeries2.LegendTitle = "Series2";
barSeries2.ShowLabels = true;
barSeries2.DataPoints.Add(new CategoricalDataPoint(141, "White"));
this.radChartView1.Series.Add(barSeries2);
this.radChartView1.ShowLegend = true;
this.radChartView1.MouseClick += RadChartView1_MouseClick;
}
private void RadChartView1_MouseClick(object sender, MouseEventArgs e)
{
foreach (ChartSeries series in this.radChartView1.Series)
{
foreach (BarPointElement pointElement in series.Children)
{
BarLabelElement labelElement = pointElement.Children[0] as BarLabelElement;
Rectangle rect = CartesianRenderer.ToRectangle(labelElement.GetLayoutSlot());
rect.Offset(this.radChartView1.ChartElement.View.Margin.Left, this.radChartView1.ChartElement.View.Margin.Top);
if (rect.Contains(this.radChartView1.ChartElement.Wrapper.PointFromControl(e.Location)))
{
RadMessageBox.Show(series.Name);
}
}
}
}
}
I am also attaching a short video showing the result on my end.
I hope this helps. Let me know if you need further assistance.
Regards,
Hristo
