I cannot figure out how to get the top-most window of a parent window's child windows.
I have a main application window which during the course of the application creates various child windows (by creating a window and setting the Owner property to the main window).
I need to get the top most of the main window's child windows, but after exhaustive Google searches I'm still clueless about this - how do I access the child windows' Z-ordering?
Any help would be very much appreciated.
WPF sure is a different beast

Have you tried anything along these lines?
this.Topmost ???
This is a dependency property ...
Also I this you might be able to do something like this via the application class ... sorry I've never had to do anything like this.

Hmmm, I guess I could use that one in some way - I ended up going a different route though.
But thanks for the reply - appreciated.

Well I did something entirely different.
The problem was that my program (an image processing application) may open a lot of windows in the course of a run, and when the user chooses some action from the menu/tool bar it should only affect the top most window owned by the main window.
So what I did instead was to handle the child window's Activated event. In the event handler I then simply saved a reference to the window in the main window. That way I could simply call mainWindow.ActiveWindow to get the top most child window.
Basically my problem is that I need some kind of pseudo MDI which WPF does not support - but this works quite nicely.

Looking into my trusty (almost crusty) textbook "Programming WPF" by Sells and Griffiths, I came across this piece of code that sets up a menu:
WindowMenu.Items.Clear()
foreach (Window window in Application.Current.Windows) {
MenuItem item = new MenuItem();
Item.Header = window.Title;
Item.Click += windowMenuItem_Click;
Item.Tag = window;
Item.IsChecked = window.IsAcitve;
Item.windowMenu.Items.Add(item);
}
Note, the use of window.IsActive.

Nice snippet. Thanks for letting me know about it.

Hello Katelva,
This version that you refered is old version. You should install Silverlight 2 and Blend 2.5. You can get all required installer from this link[^].
If you are facing some problems in installation, please read this post[^].
Hope it help.

Hi All,
Hope we're all well.
I've run into a bit of an issue that I'm hoping some here might be able to help with. After reading this article:
http://www.codeproject.com/KB/WPF/wpfskins.aspx[^]
I set about creating some themes for an application I'm working on. All works fine if the style code held in xaml is in one file. As soon as you have a dictionary in a source .dll that is a 'merged dictionary' the host application says that it can't find the merged dictionaries. Does anyone have any ideas?
I've tried the various methods for loading the external skin provided in the CP article source but always with the same results. It finds the 'parent' xaml dictionary and complains about not finding the 'child' xaml files ...
The Exception created is a TargetInvocationException on:
"{"Cannot locate resource 'defaulttheme_basecontrols.xaml'."}"
Could it possibly be an AssemblyInfo problem? I currently have this in the theme .dll:
[assembly: ThemeInfo(
ResourceDictionaryLocation.None, //where theme specific resource dictionaries are located
//(used if a resource is not found in the page,
// or application resource dictionaries)
ResourceDictionaryLocation.SourceAssembly //where the generic resource dictionary is located
//(used if a resource is not found in the page,
// app, or any theme specific resource dictionaries)
)]
I'm going to have a read up about the ThemeInfo stuff now.
Cheers,
Jammer

I have gotten this all working now.
Rather than having the following in the <SkinName>.dll:
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="DefaultTheme_Controls.xaml" />
</ResourceDictionary.MergedDictionaries>
It needs to be:
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/<SkinName>;component/DefaultTheme_Controls.xaml" />
</ResourceDictionary.MergedDictionaries>

Have you supplied the fully qualified assembly name where the XAML resides. For instance:
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Assembly1;component/childResource.xaml" />
</ResourceDictionary.MergedDictionaries> We had this problem before.

How does this apply to WPF?

I just provided the link to what I thought might be a tool that CP members might find interesting. If this tool misrepresenting what it purports to be, then, tell the authors of it via the link I gave.

Hello,
I just downloaded Woodgrove Finance Application from this link[^]
I have VS 2008 Team System and am on Windows Xp. I extracted the application and opened it in VS 2008. But not working. I got some errors. When I take a look the details, the project is not able to find the assembly called WoodgroveFinanceHost.
xmlns:WoodgroveFinanceHost ="clr-namespace:WoodgroveFinanceHost;assembly=WoodgroveFinanceHost"
I have checked the assembly and I found that it's already there. Anyway, I tried to remove and re-add the WoodgroveFinanceHost project from WoodgroveFinanceApplication...
but not working. WoodgroveFinanceApplication is still not able to find the WoodgroveFinanceHost ..
Any idea?
Thanks in advance.

According to this article[^], I tried the following things too..
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:YourProjectNamespace"
But doesn't work..

I'm using the 3.5 sp1 beta, this is supposed to have better error messages and that seems to be the case:
Part URI cannot start with two forward slashes. Error at object 'PortfolioDataSource' in markup file 'WoodgroveFinanceHost;component/stockhost.xaml' Line 287 Position 74.
If you change it to pack://application:,,,/FinanceExplorer/Equity.xml it should work.
