How to set ItemContainerStyle on dynamic items?

[Sean]

I'm attempting to recreate the Lookless tree view demo with dynamic items, and I'm having difficulty setting the ItemContainerSytle for new items- any idea?

RadTreeViewItem item;
    foreach (ServiceReference1.DataResult y in x) {
        item = new RadTreeViewItem();
        item.Header = y.Name
        item.ItemContainerStyle = ???

        CurrentTreeViewItem.Items.Add(item);
    }

Hello Sean,

The recommended way is to create your Style in XAML (probably using Expression Blend 2 SP1) and get the reference to it. If you put your Style in App.xaml resources you can set the x:Key attribute on the Style like this:

<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        x:Class="Telerik.Windows.Examples.App">
    <Application.Resources>
        <Style x:Key="PropertyGridOuterBorder" TargetType="Border">
            <Setter Property="MinWidth" Value="250" />
            <Setter Property="HorizontalAlignment" Value="Right" />
            <Setter Property="BorderBrush" Value="#19000000" />
            <Setter Property="BorderThickness" Value="1,0,0,0" />
        </Style>
    </Application.Resources>
</Application>

and you can get the reference in code using this syntax:

Style borderStyle = Application.Current.Resources["PropertyGridOuterBorder"] as Style;

Note that I am using the same key in code and in XAML or you will get null instead.
If you have other questions, do not hesitate to contact us.
