    I was wondering if it is possible to use the Context Menu on a Line series radchartview? I want to be able to right click on a Line series within the chart and open up a context menu that corresponds to that line and I also want to be able to do the same thing on the legend except with a separate context menu.

    Any ideas?


    Thank you,

    Hello Erik,

    Thank you for writing.

    You can enable selection in RadChartView and detect the clicked data points: RadChartView | Selection.
    Handling clicks on the series is, however, more tricky. A similar question has been discussed in the following forum thread:

    Regarding the legends, you can handle the MouseDown event of your chart and assign a particular context menu depending on the clicked element. Please check my code snippet below: 
    private void radChartView1_MouseDown(object sender, MouseEventArgs e)
        if (e.Button != MouseButtons.Right)
        RadChartView chart = (RadChartView)sender;
        RadElement element = chart.ElementTree.GetElementAtPoint(e.Location);
        LegendItemElement itemElement = chart.ElementTree.GetElementAtPoint(e.Location) as LegendItemElement;
        if (itemElement == null)
            RadElement parent = element.Parent;
            while (parent != null)
                if (parent is LegendItemElement)
                    itemElement = (LegendItemElement)parent;
                parent = parent.Parent;
        if (itemElement != null)
            this.radContextMenu1.Items.Add(new RadMenuItem(((LineSeries)itemElement.LegendItem.Element).LegendTitle));

    I hope this helps. Should you have further questions please do not hesitate to write back.
