Yes, the ContentPropertyAttribute now exists. It didn't back when this thread was active since that was the 1.1 days.

I've got this to work before. What I did is import the right namespaces, create a dependency property for the children collection "Collection(of Child)" and decorate the class with the ContentProperty attribute and point it to your collection property name.

Imports System.ComponentModel
Imports System.Windows.Markup

<ContentProperty("Children")> _
Public Class Parent

Public Shared ReadOnly ChildrenProperty As DependencyProperty = DependencyProperty.Register("Children", GetType(Collection(Of Child)), GetType(Parent), New PropertyMetadata(New Collection(Of Child)()))

Public Property Children() As Collection(Of Child)
Get
Return DirectCast(GetValue(Parent.ChildrenProperty), Collection(Of Child))
End Get
Set(ByVal value As Collection(Of Child))
SetValue(Parent.ChildrenProperty, value)
End Set
End Property

The restriction only applies to custom controls, not to Silverlight native objects.

Hm.... Im wondering then how does XamlReader know that it should add <Canvas>'s xaml tag children to Canvas.Children collection?

We do not support [edit] custom content properties in the current 1.1 Alpha release. We are looking at how best to expose later.

ContentPropertyAttribute in Silverlight?

psih128 — Tue, 08 May 2007 19:50:14 GMT

is there an equivalent for WPF ContentPropertyAttribute in Silverlight clr?

I mean I'm creating some custom control. the control contains a custom children collection. I want the xaml reader to add xaml children to that collection. so instead of

<control.children>

<control.children>

</control>

I want to be able to write

</control>
