I have the following App.xaml file:
<Application x:Class="MiniDeviceConfig.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MiniDeviceConfig.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Button.xaml"/>
<ResourceDictionary Source="CheckBox.xaml"/>
<ResourceDictionary Source="ComboBox.xaml"/>
<ResourceDictionary Source="Common.xaml"/>
<ResourceDictionary Source="GroupBox.xaml"/>
<ResourceDictionary Source="Label.xaml"/>
<ResourceDictionary Source="LinkButton.xaml"/>
<ResourceDictionary Source="ListBox.xaml"/>
<ResourceDictionary Source="ListView.xaml"/>
<ResourceDictionary Source="RadioButton.xaml"/>
<ResourceDictionary Source="Tooltip.xaml"/>
<ResourceDictionary Source="Window.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
In my application, my main window is MiniDeviceConfig.xaml (as seen above). In my Button.xaml file, I clearly set the button height to some obscene number. And, this size is reflected in my main window's buttons. However, some action on the main window triggers a modal window that has more buttons on it. I was expecting the same tall buttons but no such luck. How do I get the style to propagate into all windows in the application?
You can try very helpful class ThemeManager from http://wpfthemes.codeplex.com. In our project we had similiar problems and solve it by using it.
Figured it out. There were other resources included that were conflicting.

I have these dictionaries:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Resources/Languages/English.xaml"/>
<ResourceDictionary Source="Resources/Themes/All.xaml"/>
<ResourceDictionary Source="Resources/Themes/Green.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
I want to remove the dictionaries in C#. Tried these but failed:
this.Resources.MergedDictionaries.Clear();
this.Resources.MergedDictionaries.Remove(this.Resources.MergedDictionaries[0]);
I get this error when I use .Clear() method.
I was able to clear the merged dictionary using this line:
this.Resources.MergedDictionaries[0].Clear();
I then added the wanted dictionary with this line:
this.Resources.MergedDictionaries.Add(languageResourceDictionary);
i am Using the Fluent-Ribbons to create my view in wpf.
to have a better organisation of my code i wanted to put the different RibbonTabItems into their own files.
The problem is:
the designer does not show the content of the ribbontab.
I only see the a blank page.
Is there a way to make the RibbonTab visible in the designer?
If anyone else lands here from google, I was having this situation where the ribbon was not only invisible in the designer, but also not showing at runtime. After spending some time, I found that you have import generic fluent ribbon theme resources into your Window or Application Resources section, like this:
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/Fluent;component/Themes/Generic.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>
After this my ribbon started showing in the designer as well as at runtime.
You can also use other themes in the same way. Just override the generic theme like this:
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/Fluent;component/Themes/Generic.xaml" />
<!-- change "Cobalt" to the color you want -->
<ResourceDictionary Source="pack://application:,,,/Fluent;component/Themes/Themes/Dark.Cobalt.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>
Hope this helps someone down the road.

I'm trying to split up a ResourceDictionary containing styles for multiple controls in our current UWP application. The file has grown to about 3000 lines and has become a living hell to manage, so I decided to split it up into smaller, more specific ResourceDictionaries and include them using MergedDictionaries.
App.xaml
<common:BootStrapper x:Class="Asteria.Ion.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:common="using:Template10.Common"
xmlns:styles="using:Asteria.Ion.Styles"
RequestedTheme="Dark">
<common:BootStrapper.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles\Custom.xaml" />
<ResourceDictionary Source="Styles\CustomControls.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</common:BootStrapper.Resources>
</common:BootStrapper>
CustomControls.xaml contains references to other ResourceDictionaries.
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:controls="using:Template10.Controls"
xmlns:behaviors="using:Template10.Behaviors"
xmlns:interactivity="using:Microsoft.Xaml.Interactivity"
xmlns:local="using:Asteria.Ion.Styles">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Shared.xaml" />
<ResourceDictionary Source="Templates.xaml" />
<ResourceDictionary Source="ComponentBlock.xaml" />
<ResourceDictionary Source="FlowAgent.xaml" />
<ResourceDictionary Source="Planning.xaml" />
<ResourceDictionary Source="ProjectDialog.xaml" />
<ResourceDictionary Source="Inspector.xaml" /-->
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
This will always produce the following exception:
Failed to assign to property 'Windows.UI.Xaml.ResourceDictionary.Source' because the type 'Windows.Foundation.String' cannot be assigned to the type 'Windows.Foundation.Uri'. [Line: 12 Position: 37]
I've tried changing the source URI numerous times, but it keeps giving this error. Only commenting out all the ResourceDictionary elements in CustomControls.xaml helps. But then I get exceptions concerning missing styles of course.
Some URI formats I've tried:
/Styles/Shared.xaml
Styles/Shared.xaml
Styles\Shared.xaml
.\Shared.xaml
ms-appx:///Styles/Shared.xaml
None of them work.
Any advice would be appreciated.
In the end it had nothing to do with the URI structure, but with a combination of ThemeDictionaries and MergedDictionaries.
What was working before:
In App.Resources:
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles/Themes.xaml" />
<ResourceDictionary Source="Styles/CustomControls.xaml" />
</ResourceDictionary.MergedDictionaries>
Where Themes.xaml contained ThemeDictionaries and CustomControls.xaml contained <Styles> ( a lot of them ).
After splitting CustomControls.xaml, it no longer contained any styles, but only MergedDictionaries.
Looking something like this:
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="ControlStyles/ProjectDialog.xaml" />
<ResourceDictionary Source="ControlStyles/Inspector.xaml" />
</ResourceDictionary.MergedDictionaries>
Inspector.xaml contained a Style using {ThemeResource} and it appears that's where it went wrong. The solution/work-around in the end was to include a MergedDictionaries with a references to Themes.xaml in Inspector.xaml.
Now if anyone can explain the exact reasoning behind this solution, I'd be much obliged.
From the error message,XAML Compiler failed to translate the Source Property of nested ResourceDictionaries. The easiest and fastest workaround is to add the nested ResourceDictionaries in App.Xaml.cs:
protected override void OnLaunched(LaunchActivatedEventArgs e)
{
...
var applicationMergedDics = Application.Current.Resources.MergedDictionaries;
applicationMergedDics[0].MergedDictionaries.Add(new ResourceDictionary() { Source = new Uri("ms-appx:///Styles/Shared.xaml") });
applicationMergedDics[0].MergedDictionaries.Add(new ResourceDictionary() { Source = new Uri("ms-appx:///Styles/Templates.xaml") });
...
rootFrame.Navigate(typeof(MainPage), e.Arguments);
}
Notes: Don't forget to remove the MergedDictionaries in CustomControls.xaml. And the error will be gone.
I have a resource file and two views. This views use a resource file
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Dictionary1.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
And it will work while i dont put one view to the another. In this case i get this error
Cannot locate resource 'dictionary1.xaml'
How to fix it?
Use Pack Uri's
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/Assembly_Name;component/Dictionary1.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
If Dictionary1.xaml in your project's rootpath, remove '/' before Dictionary1
<ResourceDictionary Source="Dictionary1.xaml"/>
Or you can use packuri like :
/yourAssemblyName;component/Dictionary1.xaml
I've came across this error, which I couldn't find the solution for. I'm implementing an mvvm application and in main window I'm setting the main DataContext in xaml using a loader:
in App.xaml:
<Application.Resources>
<viewModel:KinectViewModelLoader x:Key="KinectViewModelLoader"/>
</Application.Resources>
In MainWindow.xaml:
<Window x:Class="KinectFittingRoom.MainWindow"
...
DataContext="{Binding KinectViewModel, Source={StaticResource KinectViewModelLoader}}">
...
</Window>
Everything was running well, but now I wanted to add some dynamic resources, so I've created some xaml files containing styles and other elements.
In example:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ModelUIElement3D x:Key="BirthdayHatModel">
...
</ModelUIElement3D>
</ResourceDictionary >
To use them in MainWindow.xaml I've added them to App.xaml file as ResourceDirectory and then my application began to crash.
App.xaml:
<Application x:Class="KinectFittingRoom.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:viewModel="clr-namespace:KinectFittingRoom.ViewModel"
StartupUri="MainWindow.xaml">
<Application.Resources>
<viewModel:KinectViewModelLoader x:Key="KinectViewModelLoader"/>
<ResourceDictionary x:Key="ResourceDictionary">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Resources/Styles/GlassButton.xaml"/>
<ResourceDictionary Source="Resources/Models/BirthdayHat.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
And now I'm getting an error on App.xaml.cs file saying that KinectFittingRoom.App.OnExit(System.Windows.ExitEventArgs) has no suitable method to override.
My overriden method:
protected override void OnExit(ExitEventArgs e)
{
KinectViewModelLoader.Cleanup();
base.OnExit(e);
}
Mabe someone could explain to me why adding ResourceDirectory node causes my application to throw an error? What can I do to include those resources and avoid such problem? I would appreciate any advice.
I think you need to change two things in your XAML:
In your App.xaml file Move the declaration of your ViewModel inside ResourceDictionary section. Also if possible you should delete x:Key="ResourceDictionary". So now your App.xaml should look like:
<Application x:Class..................>
<Application.Resources>
<ResourceDictionary>
<viewModel:KinectViewModelLoader x:Key="KinectViewModelLoader"/>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Resources/Styles/GlassButton.xaml"/>
<ResourceDictionary Source="Resources/Models/BirthdayHat.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
If after following the above step your program does not work then please follow this step along. Change the DataContext Property of your window like the code shown below:
<Window x:Class="KinectFittingRoom.MainWindow"
DataContext="{StaticResource KinectViewModelLoader}">
...
</Window>
If still your application does not work then change the order of the lines in App.OnExit() as follows:
protected override void OnExit(ExitEventArgs e)
{
base.OnExit(e);
KinectViewModelLoader.Cleanup();
}
