<maps:SfMap MapToolTipOpening="Map_MapToolTipOpening" >
            <maps:SfMap.Layers>               
                <maps:ShapeFileLayer Uri="MapsZoom.ShapeFiles.usa_state.shp" ItemsSource="{Binding Data}" 
                                     ShapeIDPath="State" ShapeIDTableField="STATE_NAME" 
                                     EnableSelection="False" LabelPath="State">
                    <maps:ShapeFileLayer.ShapeSettings>
                        <maps:ShapeSetting   ShapeStrokeThickness="1" ></maps:ShapeSetting>
                    </maps:ShapeFileLayer.ShapeSettings>
                    <maps:ShapeFileLayer.ToolTipSettings>
                        <maps:ToolTipSetting ValuePath="Candidate" x:Name="shapeTooltipSettings" >
                        </maps:ToolTipSetting>
                    </maps:ShapeFileLayer.ToolTipSettings>
                </maps:ShapeFileLayer>
	       </maps:SfMap.Layers>
        </maps:SfMap>
private void SfMaps_TooltipOpening(object sender, TooltipOpeningEventArgs e)
         {
            if ((e.Data is MapsZoom.ElectionData) && (e.Data as MapsZoom.ElectionData).State == "North Dakota")
            {
                e.Cancel = true;
            }
	}
