Example

This example toggles the MaintainAspectRatio state of the AnnRectangleEditDesigner. To see the effect of this example, perform the following actions:

  1. Select a rectangular AnnObject
  2. Run the example
  3. Drag one of the corner control points
  4. Run the example again
  5. Drag one of the corner control points

Visual BasicCopy Code
Public Sub AnnEditDesigner_MaintainAspectRatio(ByVal editDesigner As AnnRectangleEditDesigner)
   editDesigner.MaintainAspectRatio = Not editDesigner.MaintainAspectRatio
End Sub
C#Copy Code
public void AnnEditDesigner_MaintainAspectRatio(AnnRectangleEditDesigner editDesigner)
{
   editDesigner.MaintainAspectRatio = !editDesigner.MaintainAspectRatio;
}
SilverlightCSharpCopy Code
public void AnnEditDesigner_MaintainAspectRatio(AnnRectangleEditDesigner editDesigner)
{
   editDesigner.MaintainAspectRatio = !editDesigner.MaintainAspectRatio;
}
SilverlightVBCopy Code
Public Sub AnnEditDesigner_MaintainAspectRatio(ByVal editDesigner As AnnRectangleEditDesigner)
   editDesigner.MaintainAspectRatio = Not editDesigner.MaintainAspectRatio
End Sub

Remarks

When selecting an AnnRectangleObject, or any annotation object that derives from AnnRectangleObject, eight control points appear. If MaintainAspectRatio is true (default), dragging one of the four corner control points will change the size of the annotation object while maintaining its aspect ratio. If false, the aspect ratio is not preserved.

Requirements

Target Platforms: Silverlight 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
