WPF User Controls vs Custom Controls

Question

I am trying to creating a combobox with checkboxes on each line to allow multiple selecting. Would this be better as a User Control or Custom Control?

I haven't created a control before so just looking for a little advice on what direction I need to head.

Thanks.

UserControl (Composition)

Composes multiple existing controls into a reusable "group"
Consists of a XAML and a code behind file
Cannot be styled/templated
Derives from UserControl

CustomControl (Extending an existing control)

Extends an existing control with additional features
Consists of a code file and a default style in Themes/Generic.xaml
Can be styled/templated
The best approach to build a control library

In your case, I think UserControl would be better; here's an example for you:

<CheckBox Content="Property" IsChecked="{Binding Path=SomeProperty}" />
<ComboBox IsEnabled="{Binding Path=Enabled}" />

Welcome to SO. Please use simple formatting or take a good look at Markup help (on the right when you Edit). — Henk Holterman, Jun 08 '11 at 14:20

I would say use a datatemplate.

Like this: Looking for a WPF ComboBox with checkboxes

It's a lot more simple than trying to create your own control. :)

This answers the body of the question but not the title of the question. I came here by searching for the title. – Gilles Apr 30 '14 at 14:59
