DataPointMember.Lable

[Divyang]

Hi,

I am displaying total for particular stack series using following code. I want two extra functionality for below code.
1) i want click able total link so that once can redirect to drill down to child report.
2) i want to change the format of displaying numeric value in total. exp. from 1000 to 1,000.

Please note that i have displayed total in DataPointMember.Lable instead of DataPointMember.YValue.
Could you please suggest which api's are available for this.

BarSeriesDefinition seriesDefinition1 = CreateStackedBarSeriesDefinition(orientation, chartType);
                    seriesDefinition1.Appearance.Foreground = new SolidColorBrush(Colors.White);
                    seriesDefinition1.Appearance.Fill = new SolidColorBrush(Colors.Orange);
                    var style = new Style(typeof(SeriesItemLabel));
                    style.Setters.Add(new Setter(SeriesItemLabel.FontFamilyProperty, new FontFamily(ARIAL_FONT)));
                    style.Setters.Add(new Setter(SeriesItemLabel.FontWeightProperty, FontWeights.Bold));
                    style.Setters.Add(new Setter(SeriesItemLabel.FontSizeProperty, 20));
                    style.Setters.Add(new Setter(Border.BackgroundProperty, new SolidColorBrush(Colors.Transparent)));
 
                    seriesDefinition1.SeriesItemLabelStyle = style;
                    seriesDefinition1.LabelSettings.Distance = -20;
 
                    SeriesMapping seriesMapping1 = new SeriesMapping
                                                       {
                                                           LegendLabel = TOTAL,
                                                           SeriesDefinition = seriesDefinition1
                                                       };
                    seriesMapping1.ItemMappings.Add(new ItemMapping(chartXDisplayValue, DataPointMember.XCategory));
                    seriesMapping1.ItemMappings.Add(new ItemMapping(OVER_ALL_TOTAL, DataPointMember.Label, ChartAggregateFunction.Min));
                    seriesMapping1.GroupingSettings.GroupDescriptors.Add(new ChartGroupDescriptor(chartXDisplayValue));
                    seriesMapping1.GroupingSettings.ShouldFlattenSeries = true;

Hi Divyang,

To handle the first requirement, you can use the selection changed event handler, and rebind the control:

RadChart1.DefaultView.ChartArea.SelectionChanged

Another option is to use a hierarchical drilldown, as shown in this example:

Further, you can yse a format string, to show the value which you need. More information on this is available in the following topic:

I hope this information helps.
