Diagram not resizing inside Ruler.

Hi,
I have a diagram placed inside the ruler. If the window's width is 1000, then the ruler automatically fills in the width, but not the diagram.
It is always aligned in the middle of the ruler.

How do i make the diagram fill the ruler?

Sent you a sample project for this (from email surendra@eagle-india.com)

Please help.

Hi,

The size of the diagram depends only on its Bounds property. You could handle the SizeChanged event raised for the diagram’s container - Ruler or Scroll Viewer - and set larger Bounds value if you detect it's smaller than the container's ActualWidth / ActualHeight.

Change this line:
MyDiagram.Bounds = MyRuler.Document.Bounds;

which assigns diagram.Bounds to itself, to:

var scrollViewer = MyDiagram.Parent as ScrollViewer;
var b = MyDiagram.Bounds;
if (scrollViewer != null)
{
     MyDiagram.Bounds = new Rect(0, 0,
           Math.Max(scrollViewer.ActualWidth, b.Width),
           Math.Max(scrollViewer.ActualHeight, b.Height));
}

I hope that helps,
Stoyan
