Fournir une valeur sur 'System.Windows.Markup.StaticResourceHolder' a levé une exception
exemple pour afficher les éléments sélectionnés dans la même zone de liste déroulante séparés par des virgules.
mais quand j'essaie d'utiliser Usercontrol dans wpfform, je reçois cette exception
System.Windows.Markup.XamlParseException was unhandled
Message=Provide value on 'System.Windows.Markup.StaticResourceHolder' threw an exception.

InnerException:
Le problème est dû à un ordre incorrect de vos styles. Je veux dire que si nous publions un style de bouton avec référence sur la ressource statique NormalBrush, qui est déclarée sous le style, comme ceci:
<Style TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{StaticResource NormalBrush}" >
<ContentPresenter Name="ButtonCont"></ContentPresenter>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<LinearGradientBrush x:Key="NormalBrush" StartPoint="0,0" EndPoint="0,1">
<GradientBrush.GradientStops>
<GradientStopCollection>
<GradientStop Color="#FFF" Offset="0.0"/>
<GradientStop Color="#CCC" Offset="1.0"/>
</GradientStopCollection>
</GradientBrush.GradientStops>
</LinearGradientBrush>
Ce code vous donnera une telle erreur. Mais si tu changes, comme ça
<LinearGradientBrush x:Key="NormalBrush" StartPoint="0,0" EndPoint="0,1">
<GradientBrush.GradientStops>
<GradientStopCollection>
<GradientStop Color="#FFF" Offset="0.0"/>
<GradientStop Color="#CCC" Offset="1.0"/>
</GradientStopCollection>
</GradientBrush.GradientStops>
</LinearGradientBrush>
<Style TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{StaticResource ButtonBackground}" >
<ContentPresenter Name="ButtonCont"></ContentPresenter>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Tout fonctionne bien. La même chose se produit si vos ressources sont stockées dans différents fichiers xaml et que vous les joignez dans votre ResourceDictionary. Par exemple (cosider nous stockons notre NormalBrush dans Colors.xaml et Button dans Button.xaml). Cela donne une erreur:
<ResourceDictionary Source="Resources\Button.xaml" />
<ResourceDictionary Source="Resources\Colors.xaml" />
Cela devrait fonctionner erreur:
<ResourceDictionary Source="Resources\Colors.xaml" />
<ResourceDictionary Source="Resources\Button.xaml" />
Veuillez vérifier si vous avez spécifié un convertisseur dans un Xaml qui n'existe pas.
J'étais tombé sur ce problème exact. Il y a un problème avec le fichier XAML. SolidBorderBrush est absent du XAML. En l'ajoutant, l'exemple fonctionne correctement.
<SolidColorBrush x:Key="SolidBorderBrush" Color="#000" />
Ci-dessous suit le contenu complet du fichier XAML.

En utilisant un DynamicResource au lieu de StaticResource, il trouvera la ressource au moment de l'exécution, vous n'avez donc pas à vous soucier de l'ordre des déclarations dans le XAML.
Il peut y avoir des inconvénients à cela (?), Mais dans des cas particulièrement collants, cela a été la réponse à mes prières.
Vérifiez l'autorisation de votre fichier resource.resx. En haut de votre fichier, vous trouverez la liste déroulante connue sous le nom de modificateur d'accès: changez son type en 'Public'
