Hi everyone

I have a propably simple problem, that i just can't seem to figure out:

I've made an ItemsControl which has its datacontext set and shows the data as pairs of Checkboxes and TextBlocs:

<ItemsControl Name="listTaskTypes" Grid.Row="1" Grid.Column="2" Grid.RowSpan="2" ItemsSource="{Binding}" Margin="10,0,0,0" VerticalAlignment="Top" Loaded="listTaskTypes_Loaded">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <CheckBox Name="checkBoxTypeId" Tag="{Binding Path=TaskTypeID}"/>
                <TextBlock FontSize="11pt" FontFamily="Helvetica" Text="{Binding Path=Text}" />
            </StackPanel>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

My problem is that in the Loaded event of the ItemsControl, the checkboxes does not exist yet. How can i get an event when the ItemsControl is completely loaded or is this not possible?
