Question

The XAML code:

<Canvas>
    <Button x:Name="btnCanvasButton" Content="Canvas Button"
            Canvas.Left="50" />
    <Button x:Name="btnCanvasButton2" Content="Canvas Button 2"
            Canvas.Top="25"
            Width="{Binding Path=Canvas.Left, ElementName=btnCanvasButton}" />
</Canvas>

I want to bind btnCanvasButton2.Width to btnCanvasButton.Canvas.Left, but it’s not working.

I also tried Path=Canvas.LeftProperty, Path=Left, Path=LeftProperty, but no luck either.

Please advise. Thx.

Answer 1

You need to use parentheses to bind to an attached property.

You could try:

<Button x:Name="btnCanvasButton2" Content="Canvas Button 2"
        Canvas.Top="25"
        Width="{Binding Path=(Canvas.Left), ElementName=btnCanvasButton}" />
