I am working on a WPF class library, not an application. Here is an example of a shortcut that I make in C #, and I would like to “style” it with XAML.
private void CreateElement(int i)
{
UIElementOut[i] = new Label();
var uiElement = (Label)UIElementOut[i];
uiElement.HorizontalAlignment = HorizontalAlignment.Center;
uiElement.VerticalAlignment = VerticalAlignment.Center;
uiElement.FontFamily = new FontFamily(FFontInput[i]);
uiElement.FontSize = Convert.ToDouble(FontSizeIn[i]);
uiElement.Content = TextIn[i];
Brush BgBrushColor = new SolidColorBrush(RGBAToMediaColor(FBgCol[i]));
Brush FgBrushColor = new SolidColorBrush(RGBAToMediaColor(FFgCol[i]));
uiElement.Background = BgBrushColor;
uiElement.Foreground = FgBrushColor;
Uri uri = new Uri("Styles/LabelStyle.xaml", UriKind.Relative);
StreamResourceInfo info = Application.GetContentStream(uri);
System.Windows.Markup.XamlReader reader = new System.Windows.Markup.XamlReader();
ResourceDictionary myResourceDictionary = (ResourceDictionary)reader.LoadAsync(info.Stream);
Application.Current.Resources.MergedDictionaries.Add(myResourceDictionary);
Style myLabelStyle = myResourceDictionary["LabelStyle"] as Style;
uiElement.Style = myLabelStyle;
}
For this, I have a ressourcedictionnary containing my LabelStyle, everything compiles without problems.
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication1">
<Style x:Key="LabelStyle" TargetType="{x:Type Label}">
<Setter Property="Height" Value="53" />
<Setter Property="Width" Value="130" />
<Setter Property="HorizontalAlignment" Value="Left" />
<Setter Property="Margin" Value="99,71,0,0" />
<Setter Property="VerticalAlignment" Value= "Top" />
<Setter Property="Foreground" Value="#FFE75959" />
<Setter Property="FontFamily" Value="Calibri" />
<Setter Property="FontSize" Value="40" />
</Style>
but when I use my dll later, the style is not applied and I have this error message:
ERR : Assembly.GetEntryAssembly() returns null. Set the Application.ResourceAssembly property or use the pack://application:,,,/assemblyname;component/ syntax to specify the assembly to load the resource from.
here is my actual App.xaml file with the build setup per page:
<Application x:Class="WpfApplication1.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication1"
StartupUri="MainWindow.xaml">
<Application.Resources>
</Application.Resources>
How to specify the assembly to load the resource? I am new to WPF and I am stuck with this problem, thanks in advance.
EDIT 1:
I tried, since my build name is WpfApplication1 (see here http://postimg.org/image/ksyj9xi5p/ )
ResourceDictionary myResourceDictionary = Application.LoadComponent(new Uri("/WpfApplication1;component/Styles/LabelStyle.xaml", UriKind.RelativeOrAbsolute)) as ResourceDictionary;
instead
ResourceDictionary myResourceDictionary = (ResourceDictionary)reader.LoadAsync(info.Stream);
and get the same error.
