How to add MultiBindig to PointCollection?

Question

WPF

There is a code

<Polygon Grid.Row="0" Stroke="Black">
            <Polygon.Points>
                <MultiBinding Converter="{StaticResource SizeToPointsConverterUp}">
                    <Binding ElementName="Container" Path="Width"/>
                    <Binding ElementName="Row" Path="Height"/>
                </MultiBinding>
            </Polygon.Points>


        </Polygon>

The xaml constructor in the studio swears with the words:

unable to add instance of type MultiBinding to collection of type PointCollection. This can only be done for elements of type Point

Where is the logic? Help!

Answer 1

Probably because you are trying to specify multibinding for the collection.
