I have a made a Subclass of ListBox and ListBoxItem in WPF because I want to add some custom Dependency Properties to both controls. I have used this example:To override the container rendering of the ListBox, to fill the Box with my Custom ListBoxItems

The code to make this happen looks like this:

        protected override DependencyObject GetContainerForItemOverride()
    {
        CustomBoxItem container = new CustomBoxItem();

        return container;
    }

This works great but my question is: do I have to set all the dependency properties by hand? Because in my CustomBox.Xaml I cannot set Dependency Properties in the root tag. I would like to do this in the xaml:

<UserControl mycustomdp="SomeValue">

I know I can set the DP in the sample code above by doing this:

container.mycustomdp = "SomeValue";

But when I want to set bindings it's going to be much less elegant than setting the properties in XAML. Is this possible?

Sounds like the wrong thing to do. How is your custom ListBoxItem so special that you cannot achieve the same with the standard ListBoxItem and a custom Template? – Federico Berasategui Mar 26 '14 at 12:24
