Been trying to figure out, how do I capture the events from a listbox. In the template, I've added the parameter IsChecked="" which starts my method. However, the problem is trying to capture what has been checked in the method. SelectedItem only returns what is currently selected, not the checkbox.

object selected = thelistbox.SelectedItem;
DataRow row = ((DataRowView)selected).Row;
string teststring = row.ItemArray[0].ToString();    // Doesn't return the checkbox!

<ListBox IsSynchronizedWithCurrentItem="True" Name="thelistbox" ItemsSource="{Binding mybinding}">
    <ListBox.ItemTemplate>
            <DataTemplate>
                    <StackPanel>
                            <CheckBox Content="{Binding personname}" Checked="CheckBox_Checked" Name="thecheckbox"/>
                        </StackPanel>
                </DataTemplate>
        </ListBox.ItemTemplate>
</ListBox>
