But with PieSeries.ExplodeIndex

[Alexey Stachikov]

   I've used sample from http://www.syncfusion.com/support/forums/windowsphone/chart/115975

private void SfChart_SelectionChanged_1(object sender, ChartSelectionChangedEventArgs e)

{

    seg = (e.SelectedSegment) as ChartSegment;

    ChartSeriesBase series = seg.Series;

    int b1 = (series.ItemsSource as ObservableCollection<power>).IndexOf(seg.Item as power);

    if ((e.SelectedSeries as PieSeries).ExplodeIndex == b1 )

          (e.SelectedSeries as PieSeries).ExplodeIndex = -1;

    else

        (e.SelectedSeries as PieSeries).ExplodeIndex = b1;

}

But code (e.SelectedSeries as PieSeries).ExplodeIndex = -1 is not working. To de-select pie segment I have to do following:

(e.SelectedSeries as PieSeries).ExplodeIndex = 0;
(e.SelectedSeries as PieSeries).ExplodeIndex = -1;

Hi Alexey,

Thanks for using Syncfusion products.

We have analyzed the reported query. Initially the segments are not updated, we have modified the content as shown in the below code snippet. Also, we have prepared the sample based on your query. Please download it from the given below location.

Code Snippet [C#]:

private void ChartBase_OnSelectionChanged(object sender, ChartSelectionChangedEventArgs e)

        {

            var seg = (e.SelectedSegment) as ChartSegment;

            ChartSeriesBase series = seg.Series;

            int b1 = (series.ItemsSource as ObservableCollection<DataValues>).IndexOf(seg.Item as DataValues);

            if ((e.SelectedSeries as PieSeries).ExplodeIndex != b1)

                (e.SelectedSeries as PieSeries).ExplodeIndex = b1;

            else

            {

                (e.SelectedSeries as PieSeries).ExplodeIndex = -1;

                (e.SelectedSeries as PieSeries).UpdateSegments(b1,NotifyCollectionChangedAction.Reset);

            }

        }
