Styling all ListItems in an app, even those in a templated control

I've create a style for ListItems that I want to use across all ListBoxes in my application. I can set these manually like so:

<ListBox ItemContainerStyle="">

But I'm having trouble get开发者_开发问答ting the style to apply to every single ListBox in my application without touching each one and adding the above attribute.

In addition, and more importantly, I want to apply the style to list boxes used within custom templated controls. Right now I have to modify the Generic.xaml theme in the control library... not something i think I should have to do.

Fairly certain this has something to do with themes, btu having a heck of a time figuring it out.

You can do this with implicit styles in Silverlight 4.

Define your style in the regular way:

<Style x:Key="DefaultListBoxStyle" TargetType="ListBox">
    ....
<Style>

then create the implicit style:

<Style TargetType="ListBox"
       BasedOn="{StaticResource DefaultListBoxStyle}" />

you could use implicit styles. http://www.silverlightshow.net/items/Implicit-Styles-in-Silverlight-4.aspx
You define one global style for a type (in your case ListBoxItem) and then this style is the new default style for your app.

If you need any further information, just leave a comment.
