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 !

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.

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.

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 !

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.

hi

in fact i want to obtain all the control with an existing binding to add
validation rule, maxlenght, etc..

i'm storing the rules in a custm attribute of the property of the object

the object is the datacontext and i bind the property to the control
(textbox, slider, ect...)

so in the window constructor i want to enumerate the controls of this window
an detect if a binding exist and in this case
if the binding property contains a custom attribute i want to apply
validation rules etc....
