Re: Enumerating children of a type
It all feels a bit backward to me as to why a parent object would want knowledge of things in it... seems to break encapsulation or some other software rule and does't feel right. If I find myself in this situation, I try to build custom controls at the lower level that have explicit knowledge of the required elements using Template parts etc. then use databinding to pass around stuff.

Re: Enumerating children of a type
The first reply answered exactly what you require. But since we are on the topic, here is another linq extension that may be useful. If you have your own custom hierarchy of classes you (parent/child/child/child) you can specify how the tree is linked to each object and do depth & breadth first searches on it http://www.claassen.net/geek/blog/2009/06/searching-tree-of-objects-with-linq.html -David Burela On 20 April 2012 10:30, wrote: > Yep; same here. > > ** ** > > Carl. > > ** ** > > *From:* ozsilverlig ht-boun...@ozsilverlight.com [mailto: > ozsilverlight-boun...@ozsilverlight.com] *On Behalf Of *Stephen Price < > step...@perthprojects.com> > *Sent:* Thursday, 19 April 2012 6:25 PM > *To:* ozSilverlight > *Subject:* Re: Enumerating children of a type > > ** ** > > Quite common to use an extension method similar to the one shown on this > thread... > > ** ** > > http://forums.silverlight.net/t/106379.aspx > > ** ** > > We use something very close to it on the project where I am. > > ** ** > > On Thu, Apr 19, 2012 at 4:26 PM, Greg Keogh wrote: > > I find I’m often enumerating down the visual tree looking for child > controls of a certain type.
