[WPF]ItemsControl not completely loaded @Loaded event

Question

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?

Answer 1

listTaskTypes.ItemContainerGenerator.StatusChanged event handler can give you the notification on each item created on the ItemsControl.

Yeah Loaded is just the ItemsControl loaded event, the items might not have created at that moment. Just curious as to what you are trying to achieve here?. I guess you are trying to get the instance of CheckBox in the code behind? There may be better way using binding to achieve what you are looking for.

Answer 2

Try the DataContextChanged event!

When the DataContext changes, the control should be Loaded, and you can be sure it has a DataContext set as well.

Hope this helps
