Reliure dans XAML, Exception d'analyse XAML

Question

J'utilise actuellement le WPF .NET 3.5 pour le développement, à l'aide du convertisseur de mathématiques de l'IKRIV, j'ai décidé de faire une tâche mathématique dans ma conception:

<ControlTemplate x:Key="RectangleTemplate">
    <Grid Background="Transparent">
        <Rectangle x:Name="Shape" Stroke="#d69e31" Fill="{StaticResource YellowGradientBrush}">
            <!-- Create a rectangle that applies Cornering accoding to it's (in form) indicated height -->
            <Rectangle.RadiusX>
                <MultiBinding Converter="{StaticResource MathConverter}" ConverterParameter="x/2.5">
                    <!-- Error occurs in the line below -->
                    <Binding Path="Object" ElementName="{TemplateBinding Property=Button.Height}" />
                </MultiBinding>
            </Rectangle.RadiusX>
            <Rectangle.RadiusY>
                <MultiBinding Converter="{StaticResource MathConverter}" ConverterParameter="x/2.5">
                    <!-- Error occurs in the line below -->
                    <TemplateBinding Property="Button.Height" />
                </MultiBinding>
            </Rectangle.RadiusY>
        </Rectangle>
    </Grid>
</ControlTemplate>

+ EXCEPTION Assist dit:

InnerException: système.invalidcastException

Message= Impossible de lancer l'objet de type 'system.windows.templatebindingexpression' to tapez 'system.string'.

Yes, there is an error in that line. Please give some more information about where is the button you refer to in that binding.

If it's the control that you create template for, you can try to remove the line:

<!-- this line causes an error -->
<Binding Path="Object" ElementName="{TemplateBinding Property=Button.Height}" />

and replace it with a new one:

<Binding RelativeSource="{RelativeSource TemplatedParent}" Path="Height" />
