&nbsp;Hi,

We&nbsp;have&nbsp;problems&nbsp;getting&nbsp;the&nbsp;WrapDateline&nbsp;mode&nbsp;to&nbsp;work&nbsp;(panning&nbsp;continously&nbsp;both&nbsp;east&nbsp;and&nbsp;west&nbsp;of&nbsp;the&nbsp;dateline)&nbsp;with&nbsp;ShapeFileFeatureLayer&nbsp;in&nbsp;WinformsMap.&nbsp;Can&nbsp;you&nbsp;please&nbsp;guide&nbsp;us&nbsp;in&nbsp;the&nbsp;right&nbsp;direction?

We&nbsp;are&nbsp;using&nbsp;DesktopEdition.WinformsMap&nbsp;version&nbsp;5.5

Short&nbsp;version&nbsp;of&nbsp;our&nbsp;code:

private&nbsp;readonly&nbsp;LayerOverlay&nbsp;\_staticOverlay&nbsp;=&nbsp;new&nbsp;LayerOverlay&nbsp;{&nbsp;IsBase&nbsp;=&nbsp;true&nbsp;};  
  
mapSuiteControl.BackgroundOverlay.BackgroundBrush&nbsp;=&nbsp;new&nbsp;GeoLinearGradientBrush(GeoColor.GeographicColors.ShallowOcean,&nbsp;GeoColor.GeographicColors.DeepOcean,&nbsp;GeoLinearGradientDirection.UpperLeftToLowerRight);  
  
  
  
//&nbsp;add&nbsp;world&nbsp;layer  
  
var&nbsp;layer&nbsp;&nbsp;=&nbsp;new&nbsp;ShapeFileFeatureLayer(Constants.MapBaseShapeFile,&nbsp;ShapeFileReadWriteMode.ReadOnly)  
  
 {&nbsp;FeatureSource&nbsp;=&nbsp;{Projection&nbsp;=&nbsp;MapProjection.Geodetic}&nbsp;};

var&nbsp;pen&nbsp;=&nbsp;new&nbsp;GeoPen(GeoColor.StandardColors.OliveDrab);  
  
layer.ZoomLevelSet.ZoomLevel01.DefaultAreaStyle&nbsp;=&nbsp;new&nbsp;HueFamilyAreaStyle(pen,&nbsp;GeoColor.StandardColors.PaleGreen,&nbsp;6);  
  
layer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel&nbsp;=&nbsp;ApplyUntilZoomLevel.Level20;  
  
\_staticOverlay.Layers.Add(MapLayer.BackgroundMap.ToString(),&nbsp;layer);

layer.Open();  
  
ShapeFileFeatureLayer.BuildIndexFile(Constants.MapBaseShapeFile);&nbsp;//&nbsp;or&nbsp;layer.RequireIndex&nbsp;=&nbsp;false  
  
layer.WrappingMode&nbsp;=&nbsp;WrappingMode.WrapDateline;  
  
layer.WrappingExtent&nbsp;=&nbsp;layer.GetBoundingBox();&nbsp;//&nbsp;or&nbsp;layer.WrappingExtent&nbsp;=&nbsp;new&nbsp;RectangleShape(-180,90,180,-90)  
  
layer.Close();

Thanks&nbsp;

Jøran
