How could I access wpf window resoures

Question

I have this xaml

<mui:ModernWindow x:Uid="mui:ModernWindow_1" x:Class="App1.HomePage"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:mui="http://firstfloorsoftware.com/ModernUI"
  xmlns:sys="clr-namespace:System;assembly=mscorlib"
  ContentSource="/Window1.xaml"
  Title="MainWindow" Height="350" Width="525" WindowState="Maximized" MenuLinkGroups="{Binding menuLinkGroups}">
    <mui:ModernWindow.Resources>
        <sys:String x:Key="ApplicationName">Bla Bla</sys:String>
    </mui:ModernWindow.Resources>
    <Grid Style="{StaticResource ContentRoot}" Name="mainGrid">
    </Grid>
</mui:ModernWindow>

I need to reference current window resources, so I used this:

object obj = this.Resources["ApplicationName"];

But this.Resources doesn't have any resource! so obj is always null. How could I reference this window resources?

Please check if there are any Resources `this.Resources.Count` — Marcel B, Jul 23 '14 at 13:50
@user3222589: do you mean you wrote the code as an eventhandler for a button, in the codebehind for `App1.HomePage`? — Dan Puzey, Jul 23 '14 at 14:39
Thanks Dan, problem was solved and I have posted the solution, To answer your question, the button is in another window, and public method that handles this is called from the other window button event handler. — user3222589, Jul 24 '14 at 07:13

Assume that this is a FrameworkElement, like a Window, a Grid, a Button or something like that.

object obj = this.TryFindResource("ApplicationName");

hmm… strange… I saw on Codeplex that ModernWindow inherits from Window (which inherits from `FrameworkElement`) and that neither Resources nor TryFindResource is overriden. – Marcel B Jul 23 '14 at 13:35

you can use below mentioned code

var MainGrid=Application.Current.FindResource("strApp")

or

this.FindResource("ApplicationName")

MainGrid? MainGrid is not a resource it's a grid. – user3222589 Jul 23 '14 at 13:32

Assuming this is a control...

var parent = Window.GetWindow(this)

Will get the window the control is currently on, you should then be able to access the resources like you already did

parent.Resources["ApplicationName"];

the same! can't find reasonable reason for this. – user3222589 Jul 23 '14 at 13:36
I'd suspect ModernWindow is doing something 'smart' with the ResourceDictionaries (caching them or something) then and it is what is failing. – Greg B Jul 23 '14 at 13:47

Thanks all, I find the solution (I forget to update the localized dll).

I cleaned and rebuilt solution, used locbaml.exe again to generate new localized dll.

You should bind in the XAML and not in the code behind.

"res" is the namespace where the resources file is located.

In your example the namespace alias is "local":

xmlns:local="clr-namespace:Project.Resources"

So your code should look like:

<Page Title ="{x:Static local:localStrings.step1Description}" />

Where:

"local" is the namespace alias where the resources file is located.

"localStrings" is the name of the resource file.

"step1Description" is an entry in the resource file.

In my case, I'm handling this in code behind to generate a user-specific menu, menu strings are stored as resources to give multilingual support, if you have a better approach to bind directly please point me to. – user3222589 Jul 24 '14 at 07:09
