NotifyMapPropertiesChanged after the maps spatial reference has been updated.

Workaround

Need to call NotifyMapPropertiesChanged after the maps spatial reference is updated. Below you see a modified version of the customers CenterMapAt procedure with this call added. Friend Sub CenterMapAt(ByVal pCenter As IPoint) Dim geo As CGeoGraphicsCjmtk = CGeoGraphicsCjmtk.Instance If m_MapControl IsNot Nothing Then 'Test to see if we are getting near the edge of the map If ResetCentralMeridian(m_ProjectedCoordinateSystem.CentralMeridian(True), New CPosition(pCenter.Y, pCenter.X)) Then 'If so, move the central meridian to the center point entered and re-project the map m_MapControl.SpatialReference = UpdateMapCentralMeridian(pCenter.X) Refresh(MapLayer.All) End If pCenter = geo.ConvertGeographicPointToProjectedPoint(pCenter.X, pCenter.Y) m_MapControl.CenterAt(pCenter) Dim baseLayer As IBasemapLayer = TryCast(m_MapControl.Layer(m_MapControl.LayerCount - 1), IBasemapLayer) If baseLayer IsNot Nothing Then If m_UseInvalidateCache Then baseLayer.InvalidateCache() Else baseLayer.NotifyMapPropertiesChanged(m_MapControl.Map, True) End If End If End If End Sub
