Question

I have xaml that lookes like this

<ListBox> <ListBox.ItemTemplate>     <DataTemplate>         <StackPanel>             <TextBlock Text='{Binding Name}' />             <StackPanel Orientation='Vertical' x:Name='contentPanel' >             Content goes here...             </StackPanel>         </StackPanel>     </DataTemplate> </ListBox.ItemTemplate> 

The listbox binds to an object with a bool property called ShowContent. How do I get silverlight to hide the contentPanel if the object with ShowContent is false?

Answer 1

Write a BoolToVisibility IValueConveter and use it to bind to the Visibility property of your contentPanel

<StackPanel Visibility='{Binding YourBoolProperty, Converter={StaticResource boolToVisibilityResourceRef ..../> 

You can find a BoolToVisibility pretty easy anywhere.

Check IValueConveter if you are new to that. http://msdn.microsoft.com/en-us/library/system.windows.data.ivalueconverter.aspx
