Drawing a path without setting a width and height in silverlight?

I have a path inside a viewboxand canvas as such:

<Viewbox x:Name="MyViewBox" Grid.Column="1" Grid.Row="1">
                                <Canvas xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.micros开发者_StackOverflowoft.com/winfx/2006/xaml" x:Name="tick"

                                                                    Canvas.Left="0" Canvas.Top="0">

Up top I have had to define the width and height of the path. I was just wondering, is there a way I can not do that and simply allow silverlight to determine the width and height of the path from the canvas? Or perhaps define an explicit width/height like say 100,100 and force the inner path to draw to that. Currently the viewbox scales the path down to fit inside its parent grid and itw ould be ideal if the canvas could set the paths width and height such that it would fit.

I guess this sin't that important since I can always just keep defining width and height but I figure if I can make the xaml simpler I should try..

Ricks idea to use grids instead has worked quite well for the xaml above, however in this case:

 <Viewbox Visibility="Visible" x:Name="tickbox" Grid.Column="1" Grid.Row="1">
                                <Grid>

the path is displayed at a fraction of the size it actually is :-/

The Path does have a Width and Height. If you are happy with that size, you can just remove the Canvas entirely and let the Viewbox scale the Path directly.

<Viewbox x:Name="MyViewBox" Grid.Column="1" Grid.Row="1">
    <Path  .../>
</Viewbox>

Alternatively if want some space around the Path you can use a more flexible layout element than a Canvas like a Grid:

<Viewbox x:Name="MyViewBox" Grid.Column="1" Grid.Row="1">
    <Grid Margin="4">
        <Path .../>
    </Grid>
</Viewbox>

The Grid will auto-size to the Path (unlike the Canvas) and then you can add your margin, and then the Viewbox will start its scaling.
