Hi,
I'm using Radchart with more than one DataSeries.
The problem i have is that i'm not being able to know the exact DataSeries that was clicked.
On the image, you can see an example
When i click on the first blue column i'm getting the same object i get when i click on the first red collumn.
How is it possible to distinct both columns on the ItemClick Event?

Hi Nuno ,

The event handler for the ItemClick has ChartItemClickEventArgs which can give you information about the exact data point you have clicked and DataSeries to which the data point belongs.

You could check if the data series of the data point are the same as those at index x in radChart.DefaultView.ChartArea.DataSeries collection. Like this: 
if (e.DataPoint.DataSeries == this.radChart.DefaultView.ChartArea.DataSeries[0])
{
    //...
}
else
{
    //...
}

Or if that is not enough (or you are using item mappings) you could set each data series a different LegendLabel and distinguish the data series by it:
if (e.DataPoint.DataSeries.LegendLabel == "Series 1")
{
}
else if (...)
{
}

I hope this helps.
