Custom dependency property inheritance

Hi All,

I have a user control which defines a number of dependency properties. How do I configure it so that if I add a child user Control to its canvas that theses custom dependency properties are inherited?

Thanks,

Colin E.

Re: Custom dependency property inheritance

I'm not sure exactly what you need, but we don't allow custom DP inheritance. You'd have to implement your own inheritance mechanism (ugh).

Something about your scenaio seems like it is more complicated than it needs to be, but I'd need more details to understand.

ColinE,

Do you really mean inheritance, or are you talking about attached properties, like "Canvas.Top" ?

Re: Custom dependency property inheritance

Yep - it really is inheritance that I am after, I have been re-implementing a WPF pie chart I wrote within Silverlight:

http://www.codeproject.com/KB/WPF/PieChartDataBinding.aspx

One of the features of WPF I like is that you can nest User Controls, for example, offering a pie, or a pie combined with a legend. DP inheritence allows the nested control to inherit properties.

This is not the same as attached properties :-(

Thanks for your feedback - looks like I will have to do what i used to do in WinForms, provide property wrappers.
