I'm currently working on a personnal library (toolkit) to help me during my other projects.
Inside I have all my xaml style and some functions that I often use.
when I create a new application, I add my "toolkit" in the references and I add it in my app.xaml file like that :
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/ToolKit;component/styles/global.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
With that, everything is working. I just got the following error "an error occurred while finding the resourcedictionary" but when I run it my styles are good.
But when I need to create a second custom library (to integrate it in revit) I don't have any success...
I tried this link but nothing is working. I get the same error "an error occurred while finding the resourcedictionary" and when I run it I don't have my styles...
I call the styles like that :
Style="{DynamicResource Borderless}"
and I got the error "the ressource Borderless could not be resolve"
My Toolkit have the namespace "ToolKit", a folder "Styles" and all the xaml inside this folder with a "Global.xaml" that merge all the dictionaries.
How can I get my styles applied ?
thank you
Edit :
Here is the DesignTimeResources.xaml to call the style :
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/ToolKit;component/Styles/Global.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
and the Global.xaml look like this :
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:ToolKit.Styles">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Windows.xaml" />
<ResourceDictionary Source="Borders.xaml" />
<ResourceDictionary Source="Buttons.xaml" />
<ResourceDictionary Source="CheckBox.xaml" />
<ResourceDictionary Source="Label.xaml" />
<ResourceDictionary Source="ListView.xaml" />
<ResourceDictionary Source="RadioButton.xaml" />
<ResourceDictionary Source="RichTextBox.xaml" />
<ResourceDictionary Source="ScrollBar.xaml" />
<ResourceDictionary Source="TextBlock.xaml" />
<ResourceDictionary Source="TextBox.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

New to the WPF process here and trying to define a merged dictionary of a collection of merged dictionaries that are maintained in a utility DLL. I am attempting to resolve the resource location error.
Error
IOException: Cannot locate resource 'ui/wpf/imagelist16x16.xaml'
Theme.xaml
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/UI/WPF/ImageList16x16.xaml" />
<!--Future xaml file references-->
</ResourceDictionary.MergedDictionaries>
<Style x:Key="EmptyStyle"/>
</ResourceDictionary>
ImageList16x16.xaml
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:clr="clr-namespace:System;assembly=mscorlib">
<BitmapImage x:Key="Accept" UriSource="UI/Resources/Images16x16/accept.png"/>
</ResourceDictionary>
User Control Resource Reference
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/BHP_Utilities;component/UI/WPF/Theme.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
When executed, the Theme.xaml is found as the error occurs based on the dictionary reference within it. The build option for both xaml files is Page and the Custom Tool property is set to XamlIntelliSenseFileGenerator.
Since the files are in the same folder, could you try removing "/UI/WPF/"
<ResourceDictionary Source="ImageList16x16.xaml" />
I'm building a library (plugin for Revit). I have a Window in which I have included Material design successfully.
When I try adding TextBox control to this Window, I get the following error
System.Windows.Markup.XamlParseException: 'Provide value on 'System.Windows.Markup.StaticResourceHolder' threw an exception.'
Inner Exception: NotImplementedException: The method or operation is not implemented.
Since I'm building a library, I don't have an App.xaml file, so I created a resource dictionary with the following content:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.DeepPurple.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
I include it to my Window using
<Window.Resources>
<ResourceDictionary Source="/MyAsembly;component/MaterialDesign.xaml" />
</Window.Resources>
As I said, using plain simple TextBox throw an exception, no styles, no anything
<TextBox />
All the other WPF controls that I've used so far work normally after including Material design in a window/page.
I have another Window in the same app where I already have TextBox. If I try including MaterialDesign to that Window, I get the same error; without MaterialDesing, TextBox works normally. If I include MaterialDesing and comment out the TextBox, the code works normally.
Any help is highly appreciated.
EDIT: Demo app that demonstrates the problem can be found here.
You must also provide the XAML namespace along with your ResourceDictionary declaration as shown below.
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.DeepPurple.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
put this line to your main window tag
xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
I have this code in WPF window:
<Window.Resources>
<Style x:Key="MahappsStyle">
<Style.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Style.Resources>
</Style>
</Window.Resources>
The idea is to enable external styles in dictionary for single elements in my application. For example, it should work by applying style "MahappsStyle" to element called "HamburgerMenu":
<mahapps:HamburgerMenu x:Name="hamburgerMenu" Style="{StaticResource MahappsStyle}"
DisplayMode="CompactOverlay">
</mahapps:HamburgerMenu>
But this approach seems to be working only in designer, but not at runtime. What am I missing? Is there any other way to set MergedDictionaries to a single element?
UPDATE. Found the way to do that. First need to create Mahapps.xaml in application with following content:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mahapps="http://metro.mahapps.com/winfx/xaml/controls"
xmlns:local="clr-namespace:Promt.Desktop">
<ResourceDictionary.MergedDictionaries >
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml"/>
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
And then it is possible to apply to single element by:
<mahapps:HamburgerMenu>
<mahapps:HamburgerMenu.Resources>
<ResourceDictionary Source="pack://application:,,,/Promt.Desktop;component/Styles/Mahapps.xaml"/>
</mahapps:HamburgerMenu.Resources>
</mahapps:HamburgerMenu>
I'm really disappointed that ResourceDictionary can't hold x:key property. If anyone knows another approach - please post it.
UPDATE2. Even better solution from Evk (based on Laith answer).
Laith answer is close but not completely there, you need to do it this way:
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary x:Key="MahappsResources">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</ResourceDictionary>
</Window.Resources>
And then you can indeed reference by key:
<mahapps:HamburgerMenu Resources="{StaticResource MahappsResources}" />
You need to add one more ResourceDictionary definition because otherwise it treats your MahappsResources as Window.Resources (so analog to Window.Resources = new ResourceDictionary() ...) and setting key on it indeed makes no sense. When you add one more ResourceDictionary - now you are indeed adding your MahappsResources to Window.Resources dictionary, with given key, and so can reference it by that key.
Can you check if this works:
<Window.Resources>
<ResourceDictionary x:Key="MahappsResources">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>
and your controls can reference it using the key:
<mahapps:HamburgerMenu Resources="{StaticResource MahappsResources}" />
<Application x:Class="mahaapswpf.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
</ResourceDictionary.MergedDictionaries>
</Application.Resources>
</Application>
I'm trying to use a MahApps.Metro Framework and I'm supposed to include this in my App.xaml, but I get "Nested properties are not supported: ResourceDictionaries.MergedDictionaries" error and "The attachable property "MergedDictionaries" was not found in type "ResourceDictionary".
I've tried everything but still can't fix this. Any idea? Thanks.
You're missing the tag that actually creates a ResourceDictionary instance:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
...
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
I am relatively new to WPF and I am trying to apply Windows Metro Dark theme to my entire application.
I used the following in my Apps.xaml and I can see the Windows Metro Light theme properly.
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Now I want to change the theme to Dark. I understand I can always use,
ThemeManager.ChangeTheme()
But I believe there should be a way to do this with XAML effective to all the windows of the application.
My Question : Can someone point me how to do this without using ThemeManager in source code?
Try to use BaseDark instead of BaseLight. Try to change this line :
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
to this :
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseDark.xaml" />
That did the trick for me. Screenshot of my application using MahApps BaseDark and BaseLight accents:
BaseDark
BaseLight
