Hi Yatendra,
To change the colour of a layer, you can create a
temporary layer, assign the attributes (like color,outline color etc) and
then add the shape to your existing layer and redraw the map image..
The following code might help,
//*************Code for creating a temporary layer to be added onto the
existing map******
layerObj oTempLayer = new layerObj(map);
oTempLayer.type = MS_LAYER_TYPE.MS_LAYER_POLYGON;
oTempLayer.status = 1;
classObj oTempClass = new classObj(oTempLayer);
labelObj oLabel = oTempClass.label;
oLabel.color.setRGB(0,0,0);
styleObj oStyle = new styleObj(oTempClass);
oStyle.outlinecolor.setRGB(100, 12, 12);
oStyle.color.setRGB(221, 160, 221);
oTempLayer.addFeature(shape);
layer.close();
oImg = map.draw();
int i= oTempLayer.draw(map, oImg);
