Hello, you helped me with an example of this on a Pie Chart. It worked for a while but has sporadically started throwing exceptions when the chart is clicked. Here is my code and the exception. 

 Please help!private void chrtUnitsByProduct_MouseClick(object sender, HitTestEventArgs e)

{

if ((e.Point >= 0) && (e.Series >= 0) && (SDBox.SelectedValue != null))

{

// Change third chart ItemsSource here using e.DataItemdProduct p = (dProduct)e.DataItem;if (p.Channel != "All Channels")

{

// MessageBox.Show(c.Channel);DataAccess dao;

dao = (

DataAccess)App.Current.FindResource("dao");chrtUnitsByRegion.ItemsSource = dao.dGetDataByRegionForProductChannel((Int16)SDBox.SelectedValue, p.Product, p.Channel);

// <TextBlock Text="{Binding Path=DataItem.channel}" Background="Transparent" Foreground="{StaticResource FontBrush}" FontWeight="Bold" FontFamily="Calbiri" FontSize="13" HorizontalAlignment="Center"/> TextBlock tb = new TextBlock();

tb.Text =

"Channel: " + p.Channel + ", " + p.Product;tb.Background = Brushes.Transparent;

tb.Foreground = (

LinearGradientBrush)App.Current.FindResource("FontBrush");tb.FontWeight = FontWeights.Bold;tb.FontFamily = new FontFamily("Calbiri");

tb.FontSize = 11;

tb.HorizontalAlignment = HorizontalAlignment.Center;

chrtUnitsByRegion.Titles[1].Content = tb;

}

}

}
