| | 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 |

| | Re: How to obtain the controls list of a window You can use control's VisualChildrenCount property and GetVisualChild method. These members are protected so you can use them only of you derive from some control. For other cases use VisualTreeHelper and LogicalTreeHelper classes. -- HTH Stoitcho Goutsev (100) "Bill Henning" <no_spam@hotmail.com> wrote in message news:OhkAWJ7PHHA.404@TK2MSFTNGP02.phx.gbl... > It's up to the control's implementor to provide access to its logical > parent/children.

| | Re: How to obtain the controls list of a window hi thanks stoitcho and bill it works with LogicalTreeHelper but not with VisualTree in the window constructor foreach (object child in LogicalTreeHelper.GetChildren(this)) works but VisualTreeHelper.GetChildrenCount(this) always return 0 !

| | 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? If it is a control that you wrote make sure that you override and provide implementation for VisualChildrenCount and GetVisualChild members. These are the methods that the VisualTreeHelper uses to walk the visual tree. -- Stoitcho Goutsev (100) "Thierry" <newsgroup@delacroix62.fr> wrote in message news:1294C214-8329-464A-9F96-5118EAD8C8E0@microsoft.com... > hi thanks stoitcho and bill > > it works with LogicalTreeHelper but not with VisualTree > > in the window constructor > > foreach (object child in LogicalTreeHelper.GetChildren(this)) works > > but VisualTreeHelper.GetChildrenCount(this) always return 0 ! > > > > > "Stoitcho Goutsev (100)" <100@100.com> a écrit dans le message de > news:u3Pbs78PHHA.780@TK2MSFTNGP03.phx.gbl... >> You can use control's VisualChildrenCount property and GetVisualChild >> method.
