staticresource

Our designer is using Blend to style our WPF application. When he chooses local resources for properties, Blend will apply them as a {DynamicResource} instead of a {StaticResource} . My guess is that Blend does this because it enables the app to be re-themed at runtime without having to restart it. My question is: is there a significant performance cost to this additional lookup? Should we ask the designer to go back and manually change those Dynamics to Statics? Here is a great SO question that explains the difference between the types: What's the difference between StaticResource and

I've got WPF 4 app that has a number of UserControls that share styles in their child controls. So I'm creating a number of styles in my App.xaml as . For example: <Style x:Key="ViewTitle" TargetType="{x:Type Border}"> <Setter Property="BorderBrush" Value="LightGray" /> <Setter Property="HorizontalAlignment" Value="Stretch" /> <Setter Property="VerticalAlignment" Value="Top" /> </Style> Then in my UserControls I use StaticResource to reference them, for example: <Border Style="{StaticResource ViewTitle}"> <TextBlock Margin="6,3,4,5" FontSize="18" FontWeight="Bold" Foreground="White"

I am trying to create a new resource in one xaml file and reference it in another xaml file. i.e I define <Window.Resources> <ImageBrush x:Key="TileBrush" TileMode="Tile" ViewportUnits="Absolute" Viewport="0 0 32 32" ImageSource="MyImageButton.png" Opacity="0.3"> </ImageBrush> </Window.Resources> And attempt to use it in another xaml file by <Grid> <Button Background="{StaticResource TileBrush}" Margin="5" Padding="5" FontWeight="Bold" FontSize="14"> A Tiled Button </Button> </Grid> However I get the error "StaticResource reference 'TileBrush' was not found." I can reference the resource from

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
