Oops : )
I wasn't using a callback my dep property to update the CLR property :)
Public Shared ReadOnly ItemTemplateProperty As DependencyProperty =
DependencyProperty.Register("ItemTemplate", GetType(UserControl),
GetType(SomeContainer), New PropertyMetadata(New
PropertyChangedCallback(AddressOf SetItemTemplateCallback)))
Public Shared Sub SetItemTemplateCallback(ByVal obj As DependencyObject, ByVal
propertyValue As DependencyPropertyChangedEventArgs)
CType(obj, SomeContainer).ItemTemplate = CType(propertyValue.NewValue,
UserControl)
End Sub

Subject: [OzSilverlight] Data Binding Question
Hi all,
I have a UserControl which I want to bind a property to from it's own XAML
markup...
The control has a property on it called ChildControl and I want to bind a value
to it from my ViewModel. I don't want to bind to this property from the control
that created it (i.e. <my:Control ChildControl="{Binding blah}"/>
I want to do this:
<UserControl x:Class="MyProject.SomeContainer"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation";
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml";
xmlns:my="clr-namespace:MyProject"
Width="{Binding ConfiguredWidth}" <-- Works
Height="{Binding ConfiguredHeight}" <-- Works
my: SomeContainer.ItemTemplate="{Binding ChildControl,
Mode=OneTime}" <-- Doesn't work
>
The property ChildControl that I'm binding to here gets called and the control
is returned but the binding is not completed (I don't think the Dep property is
communicating with the CLR property)...
e.g.
My Dep Prop (Public Shared ReadOnly ItemTemplateProperty As DependencyProperty)
references my CLR prop (Public Property ItemTemplate() As UserControl) but the
setter is never called on the CLR prop.
Any assistance would be helpful.
Thanks,
Jordan.
