Encuadernación en XAML, XAML Parse la excepción

Question

Actualmente estoy usando el WPF .NET 3.5 para el desarrollo, utilizando el convertidor de matemáticas de IKRIV, decidí hacer una tarea matemática en mi diseño:

<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>

+ Asistencia de excepción dice:

InNerException: System.InvalidcastException

Mensaje= No se puede colocar el objeto de tipo 'System.Windows.templateBindingExpression' para escribir 'System.String'.

gracias.

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" />
