So I would like to create a template copy of a ComboBox, but not define it in the MainWindow, but in a specially created resource directory.
What i got:
<Application x:Class="dingeTesten.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:dingeTesten"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary Source="Dictionary1.xaml"/>
</Application.Resources>
And now i createt a RessourceDictionaray that got called Dictionary1.xaml. In this file i want the Template Copy of my ComboBox but when i create a template i cannot choose this file:
Its in German but i cannot choose the last option RessourceDictionary to save this template in my RessourceDictionary.
I suppose that you are trying to create a style for ComboBox in Blend. To enable Resource dictionary option you have to add ResourceDictionary into MergedDictionaries in App.xaml.
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Dictionary1.xaml"/>
<ResourceDictionary Source="Dictionary2.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Then Resource dictionary option will be enabled.

I have a solution with two WPF projects: Primary and Secondary.
In the Primary project, a Window named PrimaryView instantiates an UserControl called SecondaryControl, defined in Secondary project.
SecondaryControl uses SecondaryStyle, which is defined in SecondaryResourceDictionary (as you might have guessed already, defined in SecondaryProject).
The fact is: when I try to run the solution, I get a XamlParseError, and digging InnerExceptions I eventually find the culprit, the ResourceNotFound error.
So my questions are:
If SecondaryControl and its SecondaryStyle are defined in the same assembly, why can't I instantiate it it PrimaryAssembly?
Should I make SecondaryStyle available to PrimaryProject namespace somehow? Why?
I try to help you by explanation how it works in my projects.
A separate assembly contains a common control and common resource dictionary like this:
CommonResources.xaml
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<!-- Some resources -->
</ResourceDictionary>
SomeCommonControl.xaml
<UserControl x:Class="YourAssembly.SomeCommonControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/YourAssembly;component/CommonResources.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
<!-- Some specific content -->
</UserControl>
I can use this control and resources from another assemblies and WPF-projects like this:
<Window x:Class="YourWPFProject.SomeWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:common="clr-namespace:YourAssembly">
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/YourAssembly;component/CommonResources.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>
<common:SomeCommonControl />
</Window>
I hope this will help you.
I've recently split my silverlight application into several smaller projects.
I've moved all of the resource dictionaries containing my styles into a separate project ("Application.Themes") I then reference these from my App.xaml file within my main project.
This works fine for the main project however all other projects that reference styles within these resource dictionaries throw "Object Reference not set to an instance of an object" exceptions within the designer, although they do compile and run without any problems and with the correct styles.
I've added an App.xaml file to each of the individual projects which references the same dictionaries as my main App.xaml file, this has made no difference.
Is there a correct way to reference resource dictionaries from another project which allows the designer to be used?
EDIT:
Here is some more information and some code snippets to demonstrate the issue I'm having
I have a styles project called "Themes" within this project I have several dictionaries that define all of the styles for the project.
Within my main App.xaml I have the following
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Themes;component/Styles/CoreStyles.xaml"/>
<ResourceDictionary Source="/Themes;component/Styles/Styles.xaml" />
</ResourceDictionary.MergedDictionaries>
If I reference styles within the main project they work correctly. however they don't for any other projects even if those projects reference the Themes project.
I've attempted to put the following at the start of each UserControl in order to resolve the styles at design time, however it still cannot resolve styles that are within the project.
<UserControl>
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Themes;component/Styles/CoreStyles.xaml"/>
<ResourceDictionary Source="/Themes;component/Styles/Styles.xaml" />
</ResourceDictionary.MergedDictionaries>
<!-- Additional Control Specific resources -->
</ResourceDictionary>
</UserControl.Resources>
<!-- The following resources are defined in Styles.XAML and don't resolve at design time and throw errors -->
<TextBlock Text="Header Test"
FontFamily="{StaticResource HeaderFontFamily}"
Foreground="{StaticResource StrongBrush}">
</UserControl>
My styles.xaml looks similar to this.
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
xmlns:behaviors="clr-namespace:Minerva.Presentation.Behavior;assembly=Minerva.Presentation"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">
<SolidColorBrush x:Key="StrongBrush" Color="{Binding Source={StaticResource MetroColors}, Path=Palette.StrongColor}" />
<FontFamily x:Key="HeaderFontFamily">Segoe UI Light, Lucida Sans Unicode, Verdana</FontFamily>
</ResourceDictionary>
Create an assembly for the styles/themes project so that this can be referenced by other projects.
In order to merge these styles into application either at app.xaml/page.xaml using MergedDictionaries
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Assembly;component/Stylesorthemes.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Hope this is useful.
I created an assembly test which contains the resource dictionary Theme.xaml
Theme.xaml code
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Thickness x:Key="GeneralThickness">10</Thickness>
</ResourceDictionary>
I created seperate silverlight project testreturns
case1.In App.xaml
<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="testreturns.App"
>
<Application.Resources>
<ResourceDictionary >
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/test;component/Theme.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
case2.Usercontrol level
<UserControl.Resources>
<ResourceDictionary >
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/test;component/Theme.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
And using it to set borderthickness of button
<Button Height="50" Width="150" BorderThickness="{StaticResource GeneralThickness}"/>
In both cases it is working for me.
Is this what you intend for?
Did you set the theme.xaml file properties BuildAction to Resource while creating assembly?
i'm using a listbox style twice in my project so i want to use it in a resource dictionary. This listbox style has two value converter's in it, so i instantiated the converters in the same resource file. at runtime though it says that the 'unknown type cannot be declared' although the same converter declarations work when using them in the mainwindow.xaml file.
Anyone have an idea?
I had the same issue until I moved the converter into the App.xaml file under the resources section. This is my sample App.xaml file, I just created a converter named TextConverter for the sample.
There are two ways to do this if you are using other ResourceDictionaries you have to use the ResourceDictionary.MergedDictionaries in all cases as seen below:
<Application x:Class="WPFFeatureSample_Application.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:converters="clr-namespace:WPFFeatureSample_Application.Converters"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary>
<converters:TextConverter x:Key="TextConverter1"></converters:TextConverter>
</ResourceDictionary>
<ResourceDictionary Source="Resources/ControlDictionary.xaml"></ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
If you do not have other resource files it would look like this:
<Application x:Class="WPFFeatureSample_Application.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:converters="clr-namespace:WPFFeatureSample_Application.Converters"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<converters:TextConverter x:Key="TextConverter1"></converters:TextConverter>
</ResourceDictionary>
</Application.Resources>
One interesting reference when using converters and Resource Dictionaries in general is this:

I have a wpf tab control which is highly customized through styles. I have referenced those styles in a resourcedictionary "TabControlResources". How do I reference "TabControlResources" in another resourcedictionary?. I have a resourcedictionary called "MainViewResources" and I would like to reference the tab style from my "TabControlResources" in that resourcedictionary.
Thanks in advance.
<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:,,,/path/to/TabControlResources.xaml" />
</ResourceDictionary.MergedDictionaries>
<other stuff...>
</ResourceDictionary>
I have the below block of XAML
'BaseStyles.xaml
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="ShinyBlue.xaml"/>
<ResourceDictionary Source="DataGrid.Generic.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
Forms that reference this work in design-time, but not in run time.
If my form references ShinyBlue.xaml or DataGrid.Generic.xaml directly, that style sheet works.
EDIT
If I paste this directly into the form, it works correctly. Appearently the problem somehow has to do with my wrapper.
Broken
<Window.Resources>
<ResourceDictionary Source="../BaseStyles.xaml"/>
</Window.Resources>
Works
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="ShinyBlue.xaml"/>
<ResourceDictionary Source="DataGrid.Generic.xaml"/>
</ResourceDictionary.MergedDictionaries>
Try including your whole path from namespace to filename:
<ResourceDictionary Source="pack://application:,,,/[YourDll];component/[YourLocation]/ShinyBlue.xaml"/>
Where [YourDll] is the name of your project, and [YourLocation] is the location where the ResourceDictionary resides in your dll.
