App.xaml style cannot be used in Usercontrol, how come?
styles, user-controls, wpf, xaml
Solution
Basically, it can not find the `StaticResource` because it is not in the file with your user control. UserControl.xaml knows nothing about App.xaml.
You should use `DynamicResource` instead, this way it will be applied at runtime.
Problem
I have a style for a textblock that is set inside my app.xaml this is then applied to textblocked through out my application and works fine. However i get an error: "could not create instance of type" if i apply this style to a textblock within my user control, how come this is a problem? ``` <UserControl x:Class="Client.Usercontrols.MyButton" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" MinHeight="30" MinWidth="40" DataContext="{Binding RelativeSource={RelativeSource Self}}"> <Button Width="Auto" HorizontalAlignment="Center"> <Border CornerRadius="5" BorderThickness="1" BorderBrush="Transparent" > <Grid> <Image Name="tehImage" Source="{Binding ImageSource}" /> <TextBlock Name="tehText" Text="{Binding Text}" Style="{StaticResource ButtonText}" /> <-- This causes error </Grid> </Border> </Button> ``` Thanks, Kohan -- App.Xaml Code -- ``` <Application x:Class="Client.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" StartupUri="Mainpage.xaml"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Styles/CascadingStyles.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> ``` -- CascadingStyles.Xaml -- ``` <Style TargetType="{x:Type TextBlock}" x:Key="ButtonText" > <Setter Property="FontSize" Value="10" /> <Setter Property="VerticalAlignment" Value="Bottom" /> <Setter Property="HorizontalAlignment" Value="Center" /> <Setter Property="FontFamily" Value="Lucida Sans Unicode" /> <Setter Property="Foreground" Value="#0F004E" /> </Style> ```
