            string value = "";
            if (Tmp.InputBox("Client Search", "Code :", ref value) == DialogResult.OK)
                this.Name = value;

            int idSel = Convert.ToInt32(this.Name);

            ShapeFile sf = new ShapeFile("C:\\Christian\\shapes\\melvin.shp");

            sf.FilterDelegate = delegate(FeatureDataRow row)
                return Convert.ToInt32(row["Id"]) == idSel;

            SharpMap.Data.FeatureDataSet ds = new SharpMap.Data.FeatureDataSet();

            SharpMap.Geometries.BoundingBox bbox = sf.GetExtents();
            sf.ExecuteIntersectionQuery(bbox, ds);


            SharpMap.Data.FeatureDataTable tbl = ds.Tables[0] as SharpMap.Data.FeatureDataTable;
            SharpMap.Layers.VectorLayer testLayer = new SharpMap.Layers.VectorLayer("Results");
            testLayer.DataSource = new SharpMap.Data.Providers.GeometryFeatureProvider(tbl);

            testLayer.Style.Fill = new SolidBrush(Color.White);
