I have a problem when using a TextBox with TextWrapping=Wrap which is inside a DataTemplate which is inside a ListBox which is inside a StackPanel.

The problem is: when I add new lines to the TextBox, both the ListBox and the StackPanel expand accordingly, but when I remove lines from the TextBox, the ListBox shrinks, but the container StackPanel doesn't shrink (it keeps the same height). That is, the TextBox height causes the DockPanel only to grow.

<pre lang="cs"><StackPanel>
            <TextBox AcceptsReturn="True" TextWrapping="Wrap" Text="{Binding Path=Text, Mode=TwoWay}" Text="{Binding Path=SomeProperty, Mode=TwoWay}" />

This seems to be a ListBox/DataTemplate problem. Is it a known bug? Does it have a workaround? (please say "yes"...)

Thanks in advance!

It seems to be, once the window is rendered with the container then we need to again render it.

The work around for this would be setting the scroll bar to the textbox

<TextBox MinWidth="100" MinHeight="45" MaxWidth="100" MaxHeight="45"
AcceptsReturn="True" TextWrapping="Wrap"
