Example

For XAML example, refer to AnnPolygonObject.

This example sets the headers of all objects in a container to be visible, at the upper-left corner of the image, and to have white text over a blue background with an Arial 11-point font.

Visual BasicCopy Code
Public Sub AnnObject_HeaderOffset(ByVal container As AnnContainer)
   For Each obj As AnnObjectBase In container.Children
      obj.IsHeaderVisible = True
      obj.HeaderOffset = New System.Windows.Point()
      obj.HeaderForeground = Brushes.White
      obj.HeaderBackground = Brushes.Blue
      obj.HeaderFontFamily = New FontFamily("Arial")
      obj.HeaderFontSize = 11.0
      obj.HeaderFontStyle = FontStyles.Normal
      obj.HeaderFontWeight = FontWeights.Bold
      obj.HeaderFontStretch = FontStretches.Normal
      obj.HeaderDecorations = New TextDecorationCollection()
      obj.HeaderDecorations.Add(TextDecorations.Underline)
   Next obj
End Sub
C#Copy Code
public void AnnObject_HeaderOffset(AnnContainer container) 
{ 
   foreach(AnnObjectBase obj in container.Children) 
   { 
      obj.IsHeaderVisible = true; 
      obj.HeaderOffset = new Point(); 
      obj.HeaderForeground = Brushes.White; 
      obj.HeaderBackground = Brushes.Blue; 
      obj.HeaderFontFamily = new FontFamily("Arial"); 
      obj.HeaderFontSize = 11.0; 
      obj.HeaderFontStyle = FontStyles.Normal; 
      obj.HeaderFontWeight = FontWeights.Bold; 
      obj.HeaderFontStretch = FontStretches.Normal; 
      obj.HeaderDecorations = new TextDecorationCollection(); 
      obj.HeaderDecorations.Add(TextDecorations.Underline); 
   } 
}

Remarks

The automation mode uses this property when you click and drag the header of an object around. Setting this property to an empty point, puts the header back at the upper left corner of the bounding rectangle of this AnnObjectBase. For more information, refer to WPF Annotation Object Headers.
