How to add different color for each data point (Bar)

Hi, I am Implementing the Bar series, I am able to draw the Bars, But I need to apply different colors to each bar. I've tried like below but no use.

        ChartPalette customPalette = chartView.Palette.ClonePalette();
            PaletteEntry barEntry = customPalette.GetEntry(ChartPalette.BarFamily);
            barEntry = customPalette.GetEntry(ChartPalette.BarFamily);
            barEntry.Fill = Color.Black;

            PaletteEntry barEntry1 = customPalette.GetEntry(ChartPalette.BarFamily);
            barEntry1= customPalette.GetEntry(ChartPalette.BarFamily);
            barEntry1.Fill = Color.Red;

            PaletteEntry barEntry2 = customPalette.GetEntry(ChartPalette.BarFamily);
            barEntry2  = customPalette.GetEntry(ChartPalette.BarFamily);
            barEntry2 .Fill = Color.Yellow;

            barSeries.CategoryBinding = new MonthResultDataBinding("Index");
            barSeries.ValueBinding = new MonthResultDataBinding("BarValue");
            barSeries.Data = (Java.Lang.IIterable)this.monthResults;
            chartView.Series.Add(barSeries);
            chartView.Palette = customPalette;

Any help on adding different color for each data point.

RadCartesianChartView selection

Hi,

I've added 3 different bar series to RadCartesianChartView and added ChartSelectionBehavior like

 RadCartesianChartView chartView = new RadCartesianChartView(this);
 BarSeries barSeries = new BarSeries();
 BarSeries barSeries1 = new BarSeries();
 BarSeries barSeries2 = new BarSeries();

barSeries.CombineMode = ChartSeriesCombineMode.Stack;
barSeries.CategoryBinding = new MonthResultDataBinding("Month");
barSeries.ValueBinding = new MonthResultDataBinding("Result");
barSeries.SelectedFillColor = Color.Green;
barSeries.SelectedStrokeColor = Color.Red;
barSeries.SelectedStrokeWidth = 5;
barSeries.Data = (Java.Lang.IIterable)this.monthResults;
chartView.Series.Add(barSeries);

barSeries1.CombineMode = ChartSeriesCombineMode.Stack;
barSeries1.CategoryBinding = new MonthResultDataBinding("Month");
barSeries1.ValueBinding = new MonthResultDataBinding("Result1");
barSeries1.SelectedFillColor = Color.Blue;
barSeries1.SelectedStrokeColor = Color.Red;
barSeries1.SelectedStrokeWidth = 5;
barSeries1.Data = (Java.Lang.IIterable)this.monthResults;
chartView.Series.Add(barSeries1);

barSeries2.CombineMode = ChartSeriesCombineMode.Stack;
barSeries2.CategoryBinding = new MonthResultDataBinding("Month");
barSeries2.ValueBinding = new MonthResultDataBinding("Result2");
barSeries2.SelectedFillColor = Color.Orange;
barSeries2.SelectedStrokeColor = Color.Red;
barSeries2.SelectedStrokeWidth = 5;
barSeries2.Data = (Java.Lang.IIterable)this.monthResults;
chartView.Series.Add(barSeries2);

ChartSelectionBehavior selectionBehavior = new ChartSelectionBehavior();
selectionBehavior.DataPointsSelectionMode = ChartSelectionMode.Single;
chartView.Behaviors.Add(selectionBehavior);

While selecting the bar it selects only one barseries value. How can I select the 3 barseries values on single click.
