BarSeries ContextMenu

[Sandogh]

Here is a sample BarSeries:

01.BarSeries barSeries = new BarSeries("Performance", "RepresentativeName");
02.barSeries.Name = "Q1";
03.barSeries.DataPoints.Add(new CategoricalDataPoint(177, "Harley"));
04.barSeries.DataPoints.Add(new CategoricalDataPoint(128, "White"));
05.barSeries.DataPoints.Add(new CategoricalDataPoint(143, "Smith"));
06.barSeries.DataPoints.Add(new CategoricalDataPoint(111, "Jones"));
07.barSeries.DataPoints.Add(new CategoricalDataPoint(118, "Marshall"));
08.this.radChartView1.Series.Add(barSeries);
09.BarSeries barSeries2 = new BarSeries("Performance", "RepresentativeName");
10.barSeries2.Name = "Q2";
11.barSeries2.DataPoints.Add(new CategoricalDataPoint(153, "Harley"));
12.barSeries2.DataPoints.Add(new CategoricalDataPoint(141, "White"));
13.barSeries2.DataPoints.Add(new CategoricalDataPoint(130, "Smith"));
14.barSeries2.DataPoints.Add(new CategoricalDataPoint(88, "Jones"));
15.barSeries2.DataPoints.Add(new CategoricalDataPoint(109, "Marshall"));
16.this.radChartView1.Series.Add(barSeries2);

How can I

1) Asign some value (e.g, an Id) to a BarSeries?

2) Asign a ContextMenu to a BarSeries to get its Id?

Hello  ,

Thank you for writing.

You should use the Name of the series to identify them. The following snippet shows how you can get the series in the ContextMenuOpening event handler and change the menu:

RadContextMenu menu = new RadContextMenu();

public RadForm1()
{
    InitializeComponent();

    radChartView1.ContextMenuOpening += RadChartView1_ContextMenuOpening;

    menu.Items.Add(new RadMenuItem("item1"));
    menu.Items.Add(new RadMenuItem("item2"));

}
private void RadChartView1_ContextMenuOpening(object sender, ChartViewContextMenuOpeningEventArgs e)
{
    var mouseLocation = radChartView1.PointToClient(Cursor.Position);

    var dataPoint = radChartView1.View.Renderer.HitTest(mouseLocation.X, mouseLocation.Y) as CategoricalDataPoint;
    var series = dataPoint.Presenter as BarSeries;

    if (series != null && series.Name == "Q1")
    {
        e.ContextMenu = menu;
    }
}

I hope this will be useful.

I don't want to assign an Id to a BarSeries. Actually I want to assign some Ids to each Bar. How can I do this?

Hello ,

Thank you for writing back.

To achieve this you need to create a class that inherits CategoricalDataPoint:

class MyCategoricalDataPoint : CategoricalDataPoint
{
    public MyCategoricalDataPoint(double value, object category) : base (value, category)
    { }

    public int Id { get; set; }
}

I hope this will be useful.
