| Guest | Re: How to obtain the controls list of a window It's up to the control's implementor to provide access to its logical parent/children. However you can walk the visual tree by using the VisualTreeHelper class. There are static methods like GetParent, GetChild, GetChildrenCount, etc. on there. -- Bill Henning Actipro Software WPF Wizard Control - http://www.actiprosoftware.com/Produ...d/Default.aspx "Thierry" <newsgroup@delacroix62.fr> wrote in message news  6543AF1-0524-4D2F-A211-92B19031A147@microsoft.com...> hi all > > i would obtain the controls list of a window (same as the this.Controls > property of a winform) > > is there any method or property to do this ? > > thanks for your help ! > > > -- > Thierry |

| Guest | Re: How to obtain the controls list of a window It is possible that there is a logical tree, but the vsiual tree doesn't exist. What is the control you are playing with?
