Remarks

Handle the MapControl.DrawMapItem event and cast its EventArgs object to the DrawMapSegmentableItemEventArgs type. The DrawMapSegmentableItemEventArgs.Segments property contains an array of the Fill, Stroke, and StrokeWidth values for MapPath or MapPie segments.

The following code sets the fill color of odd MapPie segments to red:

C#
VB.NET

csharp

private void mapControl1_DrawMapItem(object sender, DrawMapItemEventArgs e) {  
  if(e.Item is MapPie) {  
    DrawMapSegmentableItemEventArgs args = (DrawMapSegmentableItemEventArgs)e;  
    for(int i = 1; i < args.Segments.Length; i += 2){  
      args.Segments[i].Fill = Color.Red;  
    }
  }  
}

Private Sub mapControl1_DrawMapItem(ByVal sender As Object, ByVal e As DrawMapItemEventArgs)
    If TypeOf e.Item Is MapPie Then
        Dim args As DrawMapSegmentableItemEventArgs = CType(e, DrawMapSegmentableItemEventArgs)
        For i As Integer = 1 To args.Segments.Length - 1
            args.Segments(i).Fill = Color.Red
        Next
    End If
End Sub
