<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi ,
<div><br>
</div>
<div>I am trying to load a S57 dataset to my map control using GDAL.</div>
<div>I have diff types of layers i.e </div>
<div>Polygon, Point, Line and multipoint</div>
<div><br>
</div>
<div>Here I want to show polygon in the base and points and lines on top of it my code is as follows</div>
<div><br>
</div>
<div>
<div> if (layerType == "POLYGON")</div>
<div> {</div>
<div> FeatureSet fs = new FeatureSet(dt, 1, true, DotSpatial.Topology.FeatureType.Polygon);</div>
<div> fs.DataTable = dt.Clone();</div>
<div> var c = new DotSpatial.Topology.Coordinate[arrCoordinatesX.Count - 1];</div>
<div> for (int k = 0; k < arrCoordinatesX.Count - 1; k++)</div>
<div> {</div>
<div> c[k] = new DotSpatial.Topology.Coordinate(Convert.ToDouble(arrCoordinatesX[k]), Convert.ToDouble(arrCoordinatesY[k]));</div>
<div> }</div>
<div> DotSpatial.Topology.Polygon LS = new DotSpatial.Topology.Polygon(c);</div>
<div> DotSpatial.Data.IFeature currentFeature = fs.AddFeature(LS);</div>
<div> uxMap.Layers.Add(fs);</div>
<div> }</div>
<div> </div>
<div> </div>
<div> else if (layerType == "LINESTRING")</div>
<div> {</div>
<div> FeatureSet fs = new FeatureSet(dt, 1, true, DotSpatial.Topology.FeatureType.Line);</div>
<div> fs.DataTable = dt.Clone();</div>
<div> List<DotSpatial.Topology.Coordinate> coordinates = new List<DotSpatial.Topology.Coordinate>();</div>
<div> for (int k = 0; k <= arrCoordinatesX.Count - 1; k++)</div>
<div> {</div>
<div> coordinates.Add(new DotSpatial.Topology.Coordinate(Convert.ToDouble(arrCoordinatesX[k]), Convert.ToDouble(arrCoordinatesY[k])));</div>
<div> }</div>
<div> DotSpatial.Topology.LineString LS = new DotSpatial.Topology.LineString(coordinates);</div>
<div> DotSpatial.Data.IFeature currentFeature = fs.AddFeature(LS);</div>
<div> uxMap.Layers.Add(fs);</div>
<div> foreach (DataRow row in dt.Rows)</div>
<div> {</div>
<div> }</div>
<div> }</div>
<div> else if (layerType == "POINT")</div>
<div> {</div>
<div> FeatureSet fs = new FeatureSet(dt, 1, true, DotSpatial.Topology.FeatureType.Point);</div>
<div> fs.DataTable = dt.Clone();</div>
<div> foreach (DataRow row in dt.Rows)</div>
<div> {</div>
<div> for (int k = 0; k <= arrCoordinatesX.Count - 1; k++)</div>
<div> {</div>
<div> DotSpatial.Topology.Coordinate c = new DotSpatial.Topology.Coordinate(Convert.ToDouble(arrCoordinatesX[k]), Convert.ToDouble(arrCoordinatesY[k]));</div>
<div><br>
</div>
<div> DotSpatial.Topology.Point p = new DotSpatial.Topology.Point(c);</div>
<div> DotSpatial.Data.IFeature currentFeature = fs.AddFeature(p);</div>
<div> //PointCheck(ds);</div>
<div> }</div>
<div> uxMap.Layers.Add(fs);</div>
<div> //uxMap.Layers.OrderByDescending(fs, 1);</div>
<div><br>
</div>
<div> }</div>
<div> }</div>
<div><br>
</div>
<div> else if (layerType == "MULTIPOINT")</div>
<div> {</div>
<div> FeatureSet fs = new FeatureSet(dt, 1, true, DotSpatial.Topology.FeatureType.Point);</div>
<div> fs.DataTable = dt.Clone();</div>
<div> foreach (DataRow row in dt.Rows)</div>
<div> {</div>
<div> DotSpatial.Topology.Point p = new DotSpatial.Topology.Point();</div>
<div> for (int k = 0; k <= arrCoordinatesX.Count - 1; k++)</div>
<div> {</div>
<div> DotSpatial.Topology.Coordinate c = new DotSpatial.Topology.Coordinate(Convert.ToDouble(arrCoordinatesX[k]), Convert.ToDouble(arrCoordinatesY[k]));</div>
<div> p = new DotSpatial.Topology.Point(c);</div>
<div> DotSpatial.Data.IFeature currentFeature = fs.AddFeature(p);</div>
<div> }</div>
<div> DotSpatial.Topology.MultiPoint mp = new DotSpatial.Topology.MultiPoint(p);</div>
<div> uxMap.Layers.Add(fs); </div>
<div> }</div>
<div> }</div>
<div> }</div>
<div> dt.Rows.Clear();</div>
<div> }</div>
<div> }</div>
<div><br>
</div>
<div><br>
</div>
<div>So how to control this layer order so that i can see all the layers in a single map window</div>
<div><br>
