Yes. and it should not be as image.

Thanks a ton. That helped us a lot.

Hi,

After deriving from ShapeNode and supplying a ControlTemplate that uses this (or any other for that matter) Path for shape, you can override the UpdateVisuals method and apply a ScaleTransform to the shape. For example:

protected override void UpdateVisuals()
{
    base.UpdateVisuals();

    if (shape == null || shapeTransform == null)
        return;

    Rect nodeBounds = GetBounds();
    Rect shapeBounds = shape.Data.Bounds;

    double ratioX = nodeBounds.Width / shapeBounds.Width;
    double ratioY = nodeBounds.Height / shapeBounds.Height;

    shapeTransform.ScaleX = ratioX;
    shapeTransform.ScaleY = ratioY;
}
 

where shape is the Path object in the template and shapeTransform is its ScaleTransform instance.

Alternatively, you can wrap the Path in a Viewbox control http://msdn.microsoft.com/en-us/library/system.windows.controls.viewbox%28VS.95%.... Note that it's supported out of the box in SL4. For earlier versions it was included in the Silverlight Toolkit.

I hope this helps.

Hi,

You can get these references by overriding the OnApplyTemplate method and then store the values in local variables. Something like this:

        private Path shape;
        private ScaleTransform shapeTransform;
        public override void OnApplyTemplate()
        {
            base.OnApplyTemplate();

            shape = GetTemplateChild("Shape") as Path;
            shapeTransform = GetTemplateChild("ShapeTransform") as ScaleTransform;

            UpdateVisuals();
        }
 

Make sure that the template parts use the names, passed as arguments to the GetTemplateChild method. The relevant parts in xaml should look like this:

        <Path x:Name="Shape" ......... >
            <Path.RenderTransform>
                <ScaleTransform x:Name="ShapeTransform" />
            <Path.RenderTransform>
        </Path>
 

If you need anything else, please let me know.
