    Hi, when the data is updated for a chart's ItemsSource, the palette is also updated (the property is linked to a converter). However, there is a problem when trying to apply this palette to the pie series. See below for the exception.

    Parameter name: index
          at System.ThrowHelper.ThrowArgumentOutOfRangeException()
          at System.Collections.Generic.List`1.get_Item(Int32 index)
          at System.Collections.ObjectModel.Collection`1.get_Item(Int32 index)
          at Telerik.Windows.Controls.ChartView.ChartPalette.GetEntry(String family, Int32 index)
          at Telerik.Windows.Controls.ChartView.PieSeries.ApplyPaletteCore()
          at Telerik.Windows.Controls.ChartView.PresenterBase.ApplyPalette()
          at Telerik.Windows.Controls.ChartView.PresenterBase.UpdatePalette(Boolean force)
          at Telerik.Windows.Controls.ChartView.RadChartBase.ProcessPaletteChanged(Boolean force)
          at Telerik.Windows.Controls.ChartView.RadChartBase.OnPaletteChanged(DependencyObject target, DependencyPropertyChangedEventArgs args)
          at Telerik.Windows.PropertyMetadata.PropertyChangeHook.OnPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
          at System.Windows.DependencyObject.RaisePropertyChangeNotifications(DependencyProperty dp, Object oldValue, Object newValue)
          at System.Windows.DependencyObject.UpdateEffectiveValue(DependencyProperty property, EffectiveValueEntry oldEntry, EffectiveValueEntry& newEntry, ValueOperation operation)
          at System.Windows.DependencyObject.RefreshExpression(DependencyProperty dp)
          at System.Windows.Data.BindingExpression.SendDataToTarget()
          at System.Windows.Data.BindingExpression.SourcePropertyChanged(PropertyPathListener sender, PropertyPathChangedEventArgs args)
          at System.Windows.PropertyPathListener.ReconnectPath()
          at System.Windows.Data.Debugging.BindingBreakPoint.<>c__DisplayClass4.<BreakOnSharedType>b__3()

    Linear charts work fine, this is only a problem with pie charts. Pie charts load as expected - it's only when the palette is updated that this error is thrown.

    Hi Stephen,

    Given the provided information, I was not able to reproduce the exception that your are reporting. I have attached my test project for reference. In order to help you we will need to observe the problem on our side. It would be best if you could provide a runable project (perhaps a modified version of mine). Describing in more detail exactly how you are using RadPieChart could also be helpful.

    Thanks for the understanding.

    Thank you for your response. I fixed it by changing the pie series' ItemsSource, as it was set to a different collection than what the palette selector was listening to.
