mergeddictionaries

The application I'm working on has 2 ResourceDictionary, DefaultStyles.xaml and CustomStyles.xaml. Is it possible that a style in the CustomStyles dictionary uses a base style defined in the other dictionary? DefaultStyles.xaml: <Style x:Key="TextBlockDefaultStyle" TargetType="TextBlock"> <Setter Property="Margin" Value="4" /> </Style> CustomStyles.xaml: <Style x:Key="SectionTitleStyle" TargetType="TextBlock" BasedOn="{StaticResource TextBlockDefaultStyle}"> <Setter Property="FontSize" Value="16" /> </Style> App.xaml: <Application.Resources> <ResourceDictionary> <ResourceDictionary

In WPF it was possible to organise the XAML for multiple user controls by keeping the markup in separate XAML files in the themes folder and then using MergedDictionaries to import them into generic.xaml: <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="MyFirstControl.xaml" /> <ResourceDictionary Source="MySecondControl.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> With the availability of the Silverlight 3 beta introducing merged dictionary support, it seemed like it might be possible to do the same with Silverlight user

My question is very similar to this one I have a solution with a number of projects. The are two that are relevant: a class library that contains a WPF window and a project with all the WPF styles in it. Class Library with the window in Project 1 The Window's merged dictionary is something like: <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="pack://application:,,,/StyleAssembly;component/CommonStyle.xaml"/> </ResourceDictionary.MergedDictionaries> //other styles here The CommonStyle.xaml in Project 2 : <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="

I need to separate application styles to several xaml files. But I also need to define some shared values like <x:Double x:Key="SharedValue">100</x:Double> in single file for use this value in styles defined in other files. For instance: <Style x:Name="SomeStyle" TargetType="TextBox"> <Setter Property="Width" Value="{StaticResource SharedValue}"/> </Style> and in another resource dictionary file: <Style x:Name="AnotherStyle" TargetType="Button"> <Setter Property="Height" Value="{StaticResource SharedValue}"/> </Style> But when I try to define merged resource dictionary in App.xaml file

Assembly A - ResourceDictionary contains StyleA style. Assembly B - ResourceDictionary.MergedDictionaries to merge resources from Assembly A into B. I would like to create a style in Assembly B "based on" StyleA. Is it possible? I am trying to create this style: <Style x:Key="StyleB" BasedOn="{StaticResource StyleA}"> <Setter Property="Button.Foreground" Value="Khaki"/> </Style> But I get a XamlParseException exception at run-time, if I use StyleB: Cannot convert the value in attribute 'Style' to object of type 'System.Windows.Style'. Can only base on a Style with target type that is base type

i have a problem with Resource dictionaries and mergeddictionaries in general, especially when it comes to resource-lookup performance. After some performance testing i found that ResourceDictionary.get_MergedDictionaries is the call with the most hits (checked in ANTS profiler). We have around ~300 resource dictionary xamls, and a lot of them are using merged dictionary to "include" other styles. Well the get_MergedDictionaries count on one part of our application, where not much is happening, was around 10 million hits. So my guess is we are doing something completely wrong with Resource
