I have the following page layout in my application:
<Grid x:Name="ContentPanel"
Grid.Row="1">
<ScrollViewer x:Name="ScrollViewer1"
MaxHeight="600"
VerticalAlignment="Top"
HorizontalAlignment="Stretch">
<StackPanel x:Name="StackPanel1" >
<TextBlock x:Name="TextBlock1" />
<toolkit:ListPicker x:Name="ListPicker1" />
<TextBlock x:Name="TextBlock2" />
<TextBox x:Name="TextBlock3" />
<TextBlock x:Name="TextBlock4" />
<StackPanel x:Name="StackPanel2" >
<TextBlock x:Name="TextBlock5" />
<Image x:Name="Image1"/>
</StackPanel>
<ListBox x:Name="ListBox1">
<!--Customize the ListBox template to remove the built-in ScrollViewer-->
<ListBox.Template>
<ControlTemplate>
<ItemsPresenter />
</ControlTemplate>
</ListBox.Template>
<ListBox.ItemTemplate>
<DataTemplate>
<!-- .... -->
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment"
Value="Stretch" />
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
</StackPanel>
</ScrollViewer>
</Grid>
I added an external ScrollViewer
instead of the using the ListBox
's because without it the stuff above the ListBox
was taking too much room and not leaving enough space to view the ListBox
contents.
Now, the problem is if I add an item to the end of the ListBox
the ScrollIntoView
method does not work. So I need to use the ScrollViewer
's ScrollToVerticalOffset
method.
I'm adding the new item to an ObservableCollection
that is bound to the ListBox
when the user clicks a button on the application bar. How can I calculate the value to be passed to ScrollViewer.ScrollToVerticalOffset
?
Thanks for your help!
