C# find all WPF Windows

I have a C# / WPF project in Visual studio 2013. The project contains one main window and several pop-up window. Most of those pop-up windows contains control elements, including buttons.

I need to find all buttons on all windows, or actually i need to find what the "IsEnabled" property is bound to for all buttons. So in the code below, i would like to find/extract "IsChangePwdEnabled" of all buttons.

The code below is just an example of one window and one button, i have 30-40 windows in my solution and all with several buttons on.

Is there a solution to extract this data? I have tried with the LogicalTreeHelper.GetChildren(), in the initialization of the program, but with that function I need the parrent of the object which has to be searched, and i do not have that, because the window object is only created when needed.

Example of pop-up window (Logon):

<window x:Class="ManagedHMI.CLogonDialog"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:ManagedHMI" 
WindowStyle="ToolWindow"
Topmost="True"
Title="Logon" SizeToContent="WidthAndHeight"
>
<Grid Margin="5,5,5,5" >
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />
    </Grid.ColumnDefinitions>
...
<Button x:Name="ChangePwd" Width="90" Click="ChangePwd_Click" IsEnabled="{Binding Path=IsChangePwdEnabled, UpdateSourceTrigger=PropertyChanged}">

Code that creates the Logon window:

m_LogonDlg = new CLogonDialog(Logon, UnlockPc, ChangePassword, userDomain, m_language);

In my program, the "IsEnabled" property is used to check which buttons a user has access rights to use, and i want to use this functionality to make an export of userrights for all buttons.

You could use the Application.Current.Windows property to get references to the windows and then use the FindVisualChildren method from the below question to find all controls of a specific type in a specific window. Something like this:

var windows = Application.Current.Windows;
foreach(var window in windows)
{
    var buttons = FindVisualChildren<Buttons>(window);
    if(buttons != null)
    {
        foreach(var button in buttons)
        {
            bool isEnabled = buttons.IsEnabled;
            //...
        }
    }
}

Find all controls in WPF Window by type
